With the popularity of acrylic display stand, acrylic display rack becomes ubiquitous, more and more electronic markets, shopping malls, jewellery shops appeared. But there is no attention, a lot of acrylic display rack above also printed many beautiful patterns, these patterns are used up, then you know these beautiful silk screen design should pay attention to what the problem?

Is the silk screen printing, it is the principle of printing (version of the base paper or other version of the film version of the ink can be made through holes) at the time of printing, through a certain pressure so that the ink to the substrate through the hole hole Edition (transfer paper, ceramics etc.) on the formation of images or text. Although the screen printing equipment is simple, easy to operate, but there are still some problems need to pay attention to.

1, for four-color printing, aluminum mesh should use the same size and stable frame (aluminum frame, solid) with screen frame are stretched the same type and size of the screen. The use of dyeing screen helps eliminate moire, screen of tension to uniform everywhere, and four-color printing the same mesh tension 4 block screen.

2, positive film (the film) on display materials in acrylic (here must be flat glass plate), then the exposure (the so-called exposure is put in the light of very strong local sun), stretched good screen in a positive film, and parallel to the axis of the image. If the moire, left or right rotating screen, until the moire disappeared, usually 7 deg. Easy to form moire intersection area is located in the direction of the screen mesh and screen. The main color and dark color caused by Moire problems.

3, to achieve the perfect image of a copy of the most basic requirement is the quality of transparent Yang figure of film must be better, namely dot edge should be neat, no scratches and opaque. The same color printing ink color separations and use;

4, with high viscosity ink printing halftone image, the fine screen needs more strong color printing ink. With high viscosity ink printing halftone image, the fine screen needs more strong color printing ink.

5, grinding good scraping knife is essential for high quality printing, blade of shore hardness of about 70 scraping knife should be set at an angle of 75 degrees, if the angle of scraping knife too flat, the printing image may be blurred, if the angle adjustment too steep, the risk of screen printing the large deformation image. Return ink knife should not be installed too low, if so, the film version will be full of excess ink, printing is easy to blur and rub dirty.

In 6, before the first batch of screen printing, screen printing ink into the fixed print test, check layout copy level, ink, ink layer thickness, specifications, precision etc.. If the registration accuracy is poor, can be adjusted according to the fine tuning knob in front of the frame; if the color of the ink is wrong, check with the wrong ink, and immediately replaced; if the inking bad, available solvent wiping plate graphic part, so that the ink permeation properties and wettability of the substrate can be improved; if the Scripture of order harmonic levels are different, the screen should be replaced immediately.

So, only pay attention to the details in the screen printing process, can be printed out the exquisite acrylic display pattern. At the same time, because the price is cheap, convenient printing plate making and printing technology is easy to grasp, flexible manner, is not affected by the size and shape of the substrate the advantages and restrictions, more and more acrylic display rack manufacturers recognized widely.
