I have already introduced Selvedge webbing Select several methods of screen. However, it is not a simple problem to choose the screen for ribbon printing and printing processing. In addition to considering the screen, but also to consider ink, substrate costs and other constraints related to it. Enjoy the selected method and pay attention to the relevant problems, and select the appropriate screen to be handy. The following aspects should be paid attention to when selecting the screen.
First of all, consider the difficulty of ink passing through the screen, which is generally considered when selecting. The ink for intermediate tone uses the ink with high transparency. The chatter particles are relatively fine, which is more than the ratio of the chatter carrier. The ink has good trafficability. This ink can also pass through well when using a high mesh screen. Generally, the plastic ink has good trafficability, the oil ink for special purposes, and the ink with high chatter concentration, although it is a fine drawing, its trafficability is relatively poor.
If the surface of the substrate for binding ribbon printing, ribbon printing and grid belt pattern printing is rough, the lower mesh screen is generally used. Such as leather, canvas, foam sheet, wood and other materials printing. Due to the rough surface of the substrate and strong ink absorption, it is necessary to use a lower mesh screen to ensure adequate ink flow.
Select the screen according to the fineness of the original image and text lines. Contrary to the above situation, in general, high mesh screen should be selected for fine lines.
The cost shall also be considered when selecting the screen. On the premise of meeting the printing requirements, the screen with lower price shall be selected as far as possible.
