The process of making a qualified and successful resin plate is not simple. The purchase of plate making equipment is the key. The performance of the equipment is excellent and stable, and production is much easier.
Resin platemaking machines (also known as "trademark platemaking machines") currently have many brands that are fully capable of domestic production. Their main functions are: printing plates, plate washing and drying. The main production steps:
1, print version. Printing lights should use genuine high-quality and special UVA UV tube. The wavelength penetrating power and uniformity of the light directly affect the plate making effect, using more brands such as: PHILIPS. Lamps should also be replaced together when they are aging.
The printing time varies depending on the machine and the plate material. Too much time will cause the graphics and web sites to lose their edges or stencils; if they are too few, they will lose content or be impatient when they wash and print. Prior to use, obtain relevant reference data or technical guidance from the plate-making machine manufacturer and resin plate supplier.
2, vacuum. The plate-making machine should be equipped with a vacuum pressure gauge, generally need to be more than -0.08mpa in order to achieve -0.1mpa. Vacuum intensity is not large enough, uneven, and the gas is not clean, it will directly make the plate in the production scrapped, and can not be remedied. Sometimes enough strength, exhaust system is good, it does not mean you can sit back and relax. When making larger versions, you may find that the air between the vacuum film and the film is difficult to erase or go back. Then you should think of: A. Did you use the air strip? B. Is the vacuum film broken? C. Is the vacuum film too small or not pressed?
After closing the suction platform, you should continue to pay attention to the value on the vacuum pressure display. The cleanliness and transparency of the vacuum film is also very important. Normally no hair removal is used. Non-bleached rags (such as non-woven fabrics) are wiped with industrial alcohol (no medical alcohol will corrode the vacuum film) and try to avoid too much of the environment. dust. Vacuum membranes are usually replaced every 3-6 months.
3, wash version. General water temperature 30-40 Â°C, wash 50-90 seconds.
Its requirements: A. The brush should be soft and hard, flatness is high. General resin plate brush brush wire selection Î¦0.05-Î¦0.07mm, but also have a certain degree of toughness, too hard will be easy to wash bad version. B. Between the brush and the sticker platform should be flat and the pressure should be even. Otherwise, the washed version will have different shades or partial washing, and even bad version. C. Warm water. This feature can be used in warmer, hot seasons or regions. When the weather is cold, the water temperature is preferably 30-34Â°C. The water temperature is too low to wash the plate, too high is easy to wash the graphic, keep the temperature even, not too much difference. D. Wash plate self-stitching function. Standard platemakers have automatic suction devices that do not require double-sided plate cleaning and can be used permanently. Only need to lightly paste the plate, easy to paste and easy to tear. Because each time you wash a piece of paper, you stick it with double-sided tape. It wastes material, time, increases workload, and affects efficiency. It's even more difficult to tear when it's time to paste. Normally, a plate is normally produced in about 15 minutes, and the double-sided adhesive residue on the back of a clean version often takes twice as much or more time, or it may even be crushed or damaged. Graphic and text. Self-absorption (also known as self-adhesive) is currently mainly imported, its cost is very low, but the resulting benefits are very high, more commonly used such as: Germany DEP self-priming board.
4, drying. Generally 50-60Â°C, bake for 15 minutes. The baking plate should be pre-opened before the plate is washed. After the plate is washed, it must be dried as normal as soon as possible. The plated water can be evaporated as soon as possible. The temperature of the oven should be even, too high and the time will be too long to deform the graphic or media. Drying cabinet is best to use a grid-like mesh, so that the back of this version is not easy to remove water, easy to air dry and hot air circulation.
5, stereotypes. After the exposure, the time is generally the same as the printing time. This is used to reinforce the graphic and graphic text. The graphic and text are better connected to the substrate, which makes it more resistant to printing. Excessive time will make the plate prone to cracking and printing.
