Printer is used in a contact making printing plate exposure imaging equipment, we often used in screen printing to work when it is necessary, screen printing machinery, below we have a look the working principle and the function of it!
Working principle: the use of pressure (including the atmospheric pressure and the mechanical pressure), make the film and photographic version tightly, and exposure in the special light source, the photosensitive film and PS version of the chemical reaction, the original image on the photosensitive plate drying in accurately. The film and PS version tightly, and then the ultraviolet exposure.
There are two main ring print quality:
1 the vacuum tightness, film and PS version.
The 2 light source, the wavelength of ultraviolet light in a certain range, as far as possible "pure".
Characteristic.
1 the use of hard metal plate;
2 the use of high power light source operating in the bright room cool;
3 original and photosensitive materials of the original image.
Effect: printer in the printing process, the print is an important link connecting. Former process problems, partly through print, get up, and some special requirements for the printing process, can also be solved in print, process adjustment. Therefore, a direct impact on the quality of the final print quality of printing products.
The correct use of the printer, will greatly enhance our work efficiency of screen printing!
