Tech fortune laser engraver technology

Improving the productivity and profitability of short and medium display material print runs has led bma to add an inca digital spyder 320+ flatbed large format printer to its screen printing presses.
the spyder 320+ has cmyk, plus light cyan and light magenta french firm bma specializes in universal display material, such as point of sale advertising, building wraps, awnings, banners, billboards or cards and, according to inca, bma is committed to finding the materials and substrates that perfectly suit its customers' projects
the company offers printing services, together with consulting and design services.
nicolas coquet, production director at bma, said: "our company focuses on large format screen printing and digital printing.
we are receiving an increasing number of requests for short and medium runs, which were no longer profitable on our rotary screen presses." the spyder 320+, supplied by exclusive distributor fujifilm sericol, is part of inca's most popular printer range to date and prints up to a maximum speed of 80 square metres per hour, claimed the company.
its inkjet technology uses what is described as the smallest binary drop size on a commercial flatbed printer currently available, reducing graininess and creating smoother images.
in coquet's opinion, one of the advantages of the inca spyder 320+ is that it isn't a combination press and he explained: "as we already have rotary screen presses, we were looking for a machine to complement them." he feels that combination presses are ideal for operators that are starting from scratch in digital printing.
however, if a combination press breaks down, both types of production come to a halt, whereas if separate rotary and flatbed printers are available, one production method can continue, which minimizes the loss of productivity.
bma prints on all types of rigid material, from pet through plywood to polycarbonate.
coquet commented: "bma specializes in the printing of high quality four-colour images.
it is vital that quality is completely consistent and that's what we get from colour printing on the spider 320+.
we want to be able to say to the customer that we can deliver his printed product on the substrate of his choosing, whatever the thickness and type of material." he added that the arrival of the inca spyder 320+ digital flatbed large format printer allows the company to work in parallel markets and will open doors to new business for the company.

Laser wood engraving is extremely detailed and intricate art burned into wood using lasers. Laser wood engraving is a specialized type of woodburning that results in beautiful pictures with a great deal of definition and depth. While most people simply order their laser wood engravings because the creative process can be difficult, you can learn to engrave with lasers as long as you understand the technology.

    Function

  1. Laser wood engraving is almost always a creative and recreational art form. A computer program uses an image that has been scanned into the computer to guide the laser software and create the image on the piece of wood. The laser vaporizes part of the wood as it burns it to create greater depth in the picture.

    Features

  2. This laser wood engraving looks like it could jump right off the page toward you.
    This laser wood engraving looks like it could jump right off the page toward you.
    Laser wood engravings can be very large or small, depending on your mechanical capabilities. Most laser wood engravings are limited only by the size of the piece of wood that can be fed through the engraving machine. The wood that is being engraved also needs to be pretreated to prevent it from being damaged by residue from the engraving process.

    Types

  3. There are several types of laser engraving available to most people. You can send in an image and a piece of wood to an engraving company. The company will handle the process for you and return your image, along with the wood piece that now bears the image. You can also order laser wood engravings with preset images on them, such as cats, birds or outdoor scenes. Finally, you can purchase laser engraving equipment of your own so that you can scan and create the engravings. However, it is still not a very "hands-on" hobby, such as woodburning would be, because the process is handled by computer software.

    Time Frame

  4. Laser wood engraving takes several days from start to finish. Once you have selected a piece of wood to engrave, it must be sanded smooth and then finished with wood sealant or clear lacquer. After the finish is dry, the wood is ready to be engraved. Depending on the complexity of the design, this can take one to several hours. After this, the entire piece must be cleaned to remove the smoky residue created by the laser engraving process. The turnaround time on ordered, custom items is usually three to four days.

    Benefits

  5. Laser wood engravings are special gifts. They are a great way to memorialize personal photos as timeless pieces of art. They also are not particularly expensive, and you can get custom laser wood engravings starting at about $10 for small, simple pieces.

    Misconceptions

  6. Many people think that laser wood engraving is just another form of woodburning, a craft that many people learn as children and then go on to enjoy for many years. However, laser wood engraving is very unlike woodburning and cannot be done in a similar manner because the lasers must be guided by computer software. If you are interested in learning laser wood engraving, you will need to learn as much about technology as about wood and drawing.

Engraving serves many purposes. Companies rely on it to complete logos, signs and announcements. Individuals turn to engravers to personalize an item. Those wanting to be sure their item will be properly engraved should know how to compare laser engraving. Some prefer reading reviews or reading rating charts. Others prefer starting at the source, which is the focus of this article.

    How to compare laser engraving

  1. Step 1

    Study the equipment's work space. Is it small, medium or large? The work space can speak to the potential quality or lack of quality to be expected. For instance, an engraver with a small work space may not be able to handle a larger project.

  2. Step 2

    Determine the quality of the equipment. Do this by asking the engraver to tell you the make and model of his equipment. If the engraver skimped on buying a good machine to save money, then you'll likely not want to hire him for the job.

  3. Step 3

    Ask the engraver at what speed he'll be engraving your item. Certain machines call for a particular speed. Since you know what machine the engraver uses, you can determine whether the speed is a good match for that machine. Most machines have adjustable speeds.

  4. Step 4

    Ask the engraver to give you the machine's maximum cutting power. This will prove valuable if you have a tough project. There's no sense in bringing your item to them if their machine can't engrave it.

  5. Step 5

    Ask what lens the engraver will be using. According to worldlasers.com, a thin material would require the total depth of focus to be less than 0.04 inches.

1.Put lubricating oil GUIDE RAIL .

 As we know that while we are using the laser engravermachines ,there must some smoke and dust which will harm the guide rail after a period of usage.so we have to do the daily maintenance by the following: The steps:

1)Turn off the laser machine and cut the power.

2)Clean the guide rail throughtly,drop the lubricating oil there;

3)Try to move the slide rod and make sure thathe oil comes into it.

4) Do not fix the guide slide firstly.Installa the screws in the right positions and keep the slide ray on the even level. And then adjust the X light.

2.Clean the Reflector and focusing mirror

The laser machines need Cleaning and we should clean the relector and focusing mirror with the PURE alcohol weekly.

3.Oil-filling for the bearing.

In order to keep the good engraving result for the laser engraving machine,we should clean the or lubricnt all the bearings. Take a piece of soft cloth and move the dust on the bearing firstly(except the oily bearings); Take a piece of injector and suck some oil inside it,then fill the bearings with the needle and move the bearing at the same time.

4.Adjustment of synchronous belt.

There are some of synchronous belts on one laser engraving machines.If all the belts are not in the same speed during working,the engraving result will be not that acurate ie.there would be fold-over on the engraved materials. There is one standard for adjusting them well: The less nosie the engraver makes,the better situation the machine is in.

5. The maintenance of the CO2 tube.

All the CO2 laser engravers machines are using WATER as cooling system. And as the time goes on,there will be some furrings inside the laser machine’s tube. In order to make the machine works well,we can put some vinegar into the water.The vinegar will melt the furring.After that,we shall use some clean water to clean the tube.By this way,we can make the tube on the laser engraver longer.

The laser engravers are not being used only for industrial or marking field but also in customized artwork like lighter, watch, pens, etc.

Since 2005, the engraving machine core layer gradually changes to the access layer, the global market and gradually carved out of the doldrums, especially the engraving machine technology more and more popular, so that the global market demand engraving machine improved steadily year by year.
       Although in 2008 the global financial turmoil led to multi-national decline in economic indicators engraving machine, but according to the authority of the relevant international statistical analysis: the global market engraving machine of national attention to the construction of information, resulting in full year sales of about 159 million kilometers total in 2007 than 130,810,000 kilometers , an increase of 22%, and its development potential map significantly increased the demand for popular engraving machine.
        Engraving Machine related industries in China have been widely used, but also a great development and improvement. However, in technical, manufacturing, materials and processing technology before there is further room.
        Just the past year, despite the carving machine industries affected by the economic turmoil, but the engraving machine energy-saving technology is still losing its brilliant glory. To bring "green" energy, it seems overwhelming concentration of information technology news. The IC technology itself, it has been at the forefront of energy conservation. However, after upgrading and improvement, its efficiency has been to continue to raise the level of a very limited and thus continue to drive energy-saving potential of sculpture have been far less than traditional industries. In addition, the engraving machine industry itself holds the power of the proportion of total energy consumption is also very small, while the traditional industries in the energy area itself has occupied a dominant position. Given China's current energy efficiency of traditional industries is generally low, if the IC technology combined with traditional industries, energy-saving potential is considerable, so how to "carving machine" began to realize the energy conservation of traditional industries will be a hot topic in the future. From several areas cited in this article, it is not difficult to see "green" energy-saving are the traditional industries to accelerate the penetration of the trends in the field.
      Hope that the entrepreneurs interested in a higher level can play a vanguard in this field, the role of guide, so that our country's electric basket in terms of quality, technology can reach the world advanced level.

When used in laser engraving, once leaked when it would be unsafe on the human body, laser engravers manufacturers in accordance with international safety standards must design their products. In addition, users have to abide by certain rules, preferably familiar with OSHA, ANSI (American National Standards Institute) and CDRH (Center for Radiation Medicine, and equipment), the enactment of a point of order. All countries have laws and regulations accordingly.

In addition, you need to install the appropriate exhaust to exclude the process of carving the gas evaporation, equipment suppliers and technical sales staff will help you choose the right filter and exhaust devices, safety is the key to proficiency.

In carving a new material before processing, need to look at, if all of a sudden a lot of plexiglass cutting, exhaust device must be installed. Some material in the process will produce toxic by-product, it is necessary to guarantee not to let you and your employees hurt by it, but it should not affect your decision to invest in laser engravers,??????do some work.

Ease of use

Laser engraving for the operator to find the computer professionals and technical personnel than the laser more suitable. Today's laser engraving equipment is basically up and running with a high-end laser printer goes
And install as an ordinary printer driver, installed on your computer drivers laser engravers. Application of the general ordinary graphics package, CorelDRAW and the most common AutoCAD, but there are also other similar software. In addition to laser engravers and driver software, most users have to purchase a scanner, enter the existing graphics, matching the minimum standard computer configuration is: more than 300 MHz Pentium II or Celeron CPU, at least 32MB of memory, more than 500MB of hard disk, a floppy disk drive, VGA Color, mouse, Windows operating system, Windows-compatible graphics processing software. At least the scanner's optical resolution of 300DPI. Bearing in mind that like other applications, the higher CPU speed and memory configuration to increase speed.

Maintenance

Laser engravers imported brands are very durable, normal routine maintenance to ensure the normal operation of the machine and extend the service life. Maintenance, including maintaining the lens, lens and surface cleaning, use 1-20000 hours after the laser tube will need to inflate or replaced.

Affordability

Laser engraving equipment for the main complaint in its price, yes, with other images to compare the performance of methods, laser technology is more expensive, the current offer 25W of laser engravers mostly in 15 million yuan. But the other side, laser engravers made in terms of prices are also relatively high, so their owners to purchase a laser engravers processing means that he can sell high-end products to customers. In addition, as a result of laser engravers can process all types of materials, for many industries, he is undoubtedly a multi-purpose processing tool. It can be foreseen that the next few years, laser engravers ads will be produced, gifts and other industries investment.

engraving that uses acid on a metal surface is known as etching.   

etching is also used in the printmaking industry to carve an image into a metal plate with acid. once the acid is applied to the metal it bores into the surface, leaving behind lines and rough areas. 

the process of etching is believed to have begun with daniel hopfer of augsburg, germany in his profession as an armor maker. it took a while for the process to be applied to print making.

both copper and zinc have a thin coating resin layer that is resistant to acid, which makes them ideal metals to use for etching. a coating can be made of a waxy material for use with metals that do not naturally have a coating. to make the engravings and lines clearly visible through the resin the metal plates are usually smoked. the metal is then scratched with a sharp tool which exposes the metal surface without penetrating it.

after the design has been etched onto the metal plate it is placed into an acidic solution which will only attack those parts of the plate which are exposed. the process of immersing the plate into the acid is called a bath. the plate is taken out of the bath several times, and then place back in until it has been etched to the desire depth.

to prevent the acid from penetrating the metal any further a coating of varnish is applied to the metal. you will get darker prints from the lines that are exposed to the acid the longest. there are some etchers who manually apply the acid to the plates surface rather than using a bath.

when making a print the varnish is removed and then ink is heated and placed onto the plate. after the ink is applied the excess is removed so that ink only remains in the depressions created by the etching process. the plate will then be covered with a soft, moist paper and placed in the etching press.

etchers will sometimes need to use modifying techniques in order to get the right image. removing any unwanted lines is one way that etchers will modify their products. they first make a trail print, and then burnish or modify the plate to correct it.

each plate can only make a few prints, as prints will look different in various stages of the printing process. after the desired number of prints are created the plates are usually destroyed by the etcher.

different methods of etching will produce different effects. items tend to have the look of a pencil drawing when they are created using soft-ground etching, while items created using aquatint with look more like a wash drawing. hard-ground etching is usually used in combination with aquatint.

the delicate art of pictorial etching is said to have evolved in germany as well. this method has its origins in burin engraving, where artists would etch on iron and gives us the earliest evidence of artistic etching.

wet and dry etchings are the most popular methods of etching these days. a container or bin filled with a solution that dissolves the metal is used for the easy process of wet etching. a mask is required so that the solution will only etch the desired parts of the metal plate. this means you will need to find a masking material that will not be destroyed by the etching solution. this method works great for etching thin films.

there are three main categories of dry etching: reactive ion etching (rie), sputter etching, and vapor phase etching. in rie gases are mixed with plasma in order to break gas molecules into ions. these ions will then react to the metal surface as the ions are accelerated.

gases are also used with sputter etching, but the ions are not. the simplest dry etching technique is vapor phase etching. in this technique the metal plate is placed into a chamber where gases are then introduced. a chemical reaction occurs at the metals surface interacts with the gas molecules, causing the design to be dissolved into the plate.

silicon dioxide etching, which uses hydrogen fluoride, and silicon etching, which uses xenon diflouride, are the two most popular types of vapor phase etching.

 

precautions against laser engraver operation

1. no earth connection permitted during machine working. the earth wire of laser power should be connected to the earth, doors windows or water tube facilities are not allowed to be connected. the earth wire should be connected to the outside ground.

2. please check if the water pump run water or not and if the laser tube is full of water. water run out from the water pump or not enough water in the laser tube is not allowed when machine is working.

3. the water container should be larger to promise the circulating water is around 20kg. the water temperature should be below 25 degree centigrade, the circulating water should be replaced when the water temperature is very high. it is better to use purified water as circulating water, which should be promised clean and replaced every four days.

4. the reflector and focus lamp should be wiped by special camera lens paper or medical cotton buds dipped alcohol and anther. (mixing ratio is 1:1), please keep clean once a week.

5. the blower should be opened when engraving, in case pollute the lens and focus lamp.

6. the laser water tube should be running out in winter, in case the laser tube frost crack.

7. this laser light is invisible light, flammable materials and explosive goods are prohibited to be put nearby the machine, in case the laser deviation result in fire breaking out.

8. the operator leaving is not allowed during machine working, in case unnecessary losses happen.

9. open the machine by laypeople is prohibited, because there are laser and high pressure inside the machine.

10. any irrelevant total reflection or diffuse reflection goods put in the machine are not allowed, in case the laser light is reflected to people or flammable materials.

11. opening machine is prohibited under unstable pressure, or else, voltage regulator should be used.

12. operator not be trained is prohibited to operating the machine.

daily maintenance
the horizontal type machine light path is complicated, in order to make sure the light can pass through each lens and keep the max laser light power, light adjusting can improve the engraving efficiency.  there are following methods to adjust the light path.

1. wipe the lens
the reflector and the focus lamp are consumables. if the maintenance is not in time, the dust from engraving will erosion the coating of lens, if the coating of lens broke, the lens cannot reflect the light fully and will be absorbed the heat by engraving, which will impact the engraving effect and lens, broke. the following is the lens maintenance.

a) please look into the reflector surface golden film, which should be average color, if have any spots, please wipe softly by the absolute ethyl alcohol cotton buds to clean, if any broke in the golden film, please replace it.

b) screwing out the focus lens cap and take out the lens, if any spot on it, please wipe it by absolute ethyl alcohol cotton buds.

2.adjust the light path

(1) put the focus lamp on the top left corner, make the forth reflector aperture face to the third reflector, as follows figture1.
(2) look into the forth reflector incidence point, the deviation of the incidence point is adjusted through up and down ,left and right screws on the back of the first reflector.
(3) put the focus lamp to the top right corner and bottom left corner like figure 2 and 3, the second reflector deviation is adjusted through its own screws on the back of the reflector, the third reflector deviation is adjusted through the screws on the back of the reflector.
(4) put the lens to the position 4, bottom right corner, after checking no deviation, the adjustment is done, or else, adjust again by 1,2,3 positions.

Acrylic is second only to the most commonly used wood carving material, it can easily be cut and carved, there are a variety of shape and size, relatively low costs. There are two plexiglass production process: casting and rolling, laser engraving mainly produced by casting perspex, as it generated in the laser engraving of the effect of the cream is very white, transparent texture with the original have a sharp contrast, production of rolling PMMA after the laser engraving is transparent, does not have a sufficient contrast effect. Work in the face when purchasing goods dealer you would like to emphasize to the kind of high-purity, or to buy the material back to carving or cutting the possibility of the phenomenon of melting.

laser engraver laser processing is the way to burn media. Therefore, the application of laser engraving machine organic materials, CNC engraving machine is a machining method is cut grinding media, contact-type processing, the application of rigid material. Laser Cutting Engraving with flexible, cutting Every small, non-contact processing, the workpiece deformation process of small features such as no follow-up, compared to traditional processing is of great advantage, it is widely used in laser processing businesses, mainly applies to the procurement of materials glass, Standard cloth fabric, to products, leather, paper, resin, plastic, crystal glass, marble, metal and other materials that simple precision laser engraving is very high and not suitable for all but the last point as far as I know what the limit is 9 mm laser engraving materials do not need to be fixed on the top can be engraved on the three millimeters of the word it is unable to do CNC engraving.

1, the environment must comply with the requirements of the computer.


2, operating voltage must be between 210V-230V, if the voltage sub-requirements power supply must be used. Because the market regulator more power quality problems, the power supply must be used with the consent of the mid-Tang Corporation or its authorized agents approved (in power for more than 2000W, the general weight of 15 kilograms should be above).


3, the power must have good ground (must have a ground wire), otherwise, it will be well received chassis grounding conductor (such as: water pipes, heating pipes, metal doors, and so on their own ground wire installed.)


4, operation we must pay attention to safety; engraving machine of mechanical processing equipment, machine tools should be operating requirements to operate and can not wear gloves, engraving machine can not contact the equipment belongs to a more professional, if the failure of all timely contact with the dealer, only with the consent of the permit in the case of dealers, please be professional maintenance.


5, the attention of maintenance: in the use of the process must strengthen the maintenance of engraving machine, engraving machine so as to extend life. End of each engraving machine after use, we must pay attention to the engraving machine cleaned in the rail together with the oil, the machine in order to avoid corrosion by the environment, because the use of force engraved engraving machine screw a self-lubricating wear-resistant, so use only one quarter of Canada lubricants.


6, the use of spindle motor: electric carving machine carving three-month warranty, we used for the frequency of water-cooled electric carving motor, the higher the value, they must pay attention to the use of the correct motor. Motor speed and is in inverse proportion to their life. Motor operation must ensure that the water cycle, and increase appropriate preservatives, when used to the attention of the electrical reference manual to provide a choice of parameters.


7, the spindle motor protection: if there is to stop the transfer of electric carving or uneven motor speed, please cut off the power immediately and contact with dealer maintenance. If the motor stops in case switch to electric power can not be, otherwise the motor will immediately be burned by the circle, please pay attention to users must.


8, the first card protection: motor between the chuck and tool by a fixed metal friction, so the installation of refueling tool, not a long time to prevent the demolition or coolant corrosion difficulties caused by the demolition.


9, cutting coolant should not be increased: a knife used for cutting-chu (referring to wood, plexiglass, snow floating panels, etc.), plus coolant spit will seriously affect the cutting result of debris from a broken tool.


10, power supply protection: repeat boot time interval of not less than 30 seconds.


11, fan maintenance: Regular cleaning dust fans.

engraving materials

raw wood
wood is the most common material for laser engraving and cutting. wood with light color, such as birch, cherry and maple, is easily vaporized by laser and suitable for engraving. each kind of wood has its own feature, some of them is compact, such as hard wood which should use big power laser for engraving or cutting. please make a study on material before engraving.  

plywood
there is no much difference between engraving plywood and wood, the only point is engraving depth shouldn t be too deep. edge of plywood after cutting is also black like common wood, the key point is what kind of material the plywood is made of.

wood engraving
generally speaking, depth for engraving on wood is deep, so laser power is big and color of engraved graphics on hard wood is deep. for light color, you can increase the engraving speed to work several times. sometimes there is soot produced during working process, if there is paint on wood, you can clean it by wet cloth, if not, wood surface may be defiled by soot which can t be fully cleaned.      

wood cutting
generally, laser engraver can t cut wood deeply, max. cutting depth depends on wooden material and laser power. for cutting thick wood, cutting speed should be low, but wood may be burnt. users can use big reflective and focus lens to make repeated cutting.  

pigmentation
wood is just like being burnt after engraving, matched with original color, it is more like art. color depth depends on laser power and engraving speed. color of some soft wood such as birch can t be changed no matter how long you engrave it. propylene can be applied for pigmentation of finished products. 

in raster engraving, the laser traces a slowly advancing pattern across the surface in a back-and-forth motion like an inkjet printer.

in vector engraving, the line and curve of the pattern to be engraved are followed much like a pen-based plotter draws lines from a pattern outline. early engraving, laser and traditional, of signs and plaques often used prestored font outlines to scale and reproduce letters, numbers, and even logos to size with precise strokes. unfortunately, due to a lack of precision in calculating spacing s, fill areas, as cross-hatching patterns and dot-fills, sometimes showed moir�� effects or uber-patterns. moreover, the font device was not capable of rotations or dynamic scaling. today the postscript software language allows much greater flexibility. just about anything that can be described in vectors by software using postscript, such as corel draw or adobe illustrator, can be outlined, filled in with appropriate patterns, and laser engraved.

in lenticular engraving, the laser traces a slowly advancing pattern across the surface in a back-and-forth motion like an inkjet printer. areas to either side of the pattern to be engraved are ignored, thus shortening the trace for better efficiency. the advance of each line normally takes less time than the actual dot-size of the laser; the engraved lines overlap slightly to create continuity.

in all lenticular engravings, curves and diagonals will suffer if the length or position of the raster lines vary even slightly in relation to the raster scan. therefore, exact positioning and repeatability are critical in the machines design. raster engraving produces a nearly effortless fill. most images to be engraved in raster mode consist of bold letters or have large engraved areas. these can be well rasterized. rasterized photos, as in printing, have dots larger than that of the laser s spot. these are also best engraved as a lenticular image.

almost any layout software can feed a raster driver for an x-y or drum laser engraver. traditional plaque and sign engraving had to use the solid strokes of vector mode engraving, but modern shops run their laser engravers mostly in raster mode. they reserve vector mode for achieving the traditional outline look or for quickly marking out lines or hatches where a plate is to be cut.

At last count there were 70-some responses with the following favorite from “mkechaz”:

Can’t seem to understand the words I type
perhaps it would be better via Skype
A moleskin with any moniker will do
for one who wants for further spew.

There are some other real gems in there but they were also just un-printable here (but definitely good for a laugh)!
