Applications of acrylic screen printing machine processed products is now more widespread, for acrylic screen printing machine processing requirements are also increasing, especially acrylic screen printing, acrylic processing firms, which is a challenge, but also an opportunity to master high quality acrylic screen printing technology is an important acrylic processing technology.
First, to achieve a basic requirement for good quality image reproduction is transparent better positive-negative, that print outlets to be especially neat edge, opaque. Color separations and printing inks used with the same color acrylic screen printing machine.
Second, the process to improve the film a positive image on the glass, then after exposure with an exposure machine, the screen on a good stretch Positive film, and parallel to the image axis. If a moire screen left or right until the moire disappear. Easy to form a region located moire silk screen mesh direction and intersections on the screen. Problems main color and darker color moire caused more acrylic screen printing machine.
Third, the process improvement for four-color printing, you should use the same size and stability of the aluminum screen frame, screen frame are used in the same type and model of stretched mesh. Use dyed mesh helps to eliminate moire, screen tension to be uniform throughout the same and four-color printing of four network version of the stretching tension.
Fourth, process improvement lapped squeegee for high-quality printing is critical (Note scraping grinding machine is also very important), knives Shore hardness of about 70. Squeegee should be set at a 75-degree angle, if squeegee angle adjustment too flat, printed image may be blurred, if the angle is too steep transfer, screen printing danger of image distortion is large acrylic screen printing machine .
Fifth, process improvement knife back to Mexico should not pretend to be too low, and if so, will the film version of the full excess ink, print and rub dirty easily blurred.
Sixth, process change into the net halftone images with a high viscosity ink, finer screen requires more concentrated color ink. Using UV ink, tonal range halftone positive image should preferably 5% to 80%, a Shore hardness of the squeegee should be 75. To control the UV ink does not rub dirty when color overprint, recommended by the cyan, magenta, yellow, black color sequence for screen printing.
