Silk screen printing note points

In the daily work, some of the screen printing machines discussed above deal with the texture should be very noticeable

Secondly, in the case of making a large-scale imprinted film, the requirements for overprinting should be taken into consideration during printing. There should be a certain amount of idle space between each link.

First, the tension of the screen should meet the requirements.

Cloth pattern is a high priority application for silk screen printing machine used for screen printing. This article talks about the screen printing machine in the cloth pattern to pay attention to some of the main points.

On the contrary, the screen mesh can be properly reduced to improve the feel. Finally, for different screens with different number of screens, use a dedicated test strip to measure the accurate exposure time. After each print, make a detailed record to achieve data management, so that the future work is well documented. In addition, the thickness of the coating photoresist should be moderate, to avoid the occurrence of uneven thickness and air bubbles on a screen plate, so as to avoid a greater impact on the printing quality.

For cloth-patterned products mainly based on bitmaps, if the number of screen meshes is unfairly matched with the number of screens, due to the limitations of the structure of the screen itself and the limitations of the existing plate-making systems, moiré patterns that interfere with the images easily appear. In the use of film pre-shrinking, the use of the past "digging" method to improve the overprint will undermine the integrity of the graphic and thus can only improve the overprinting method using a single unitary move. Based on this, the number of screen lines increased, and the number of screen meshes selected must be increased accordingly to improve accuracy and reduce moire. The remaining idle space will leave room for the later die-cutting process. In general, for a mesh of 300 mesh/inch, the tension should be controlled between 20 and 23 N/cm. Through multiple proofing printing, the moire can be overcome by adjusting the angle of the printing pattern on a 300 mesh/inch screen to overcome the 60 line/inch dot. Because the texture film is different from the real fill pattern. If the tension of the screen is insufficient, a series of titles and title titles such as imprinting, overprinting, and hue instability will appear during printing. Moreover, the higher the number of screen lines, the finer the graphics and the higher the probability of moiré.
