The non-woven bag screen printing is more suitable for single color manuscripts with crisp text and lines, and it is also suitable for color manuscripts with large contrast and clear gradation. Through the special effects of screen printing, the reproduction is rich in expressiveness. Through the rich and thick ink layer and the contrast of light and dark tones, the texture and three-dimensional effect of the original content are fully expressed.

There are two types of screen printing photoengraving manuscripts: reflective manuscripts and transmissive manuscripts, and reflective manuscripts are usually used. Most color photography uses transmissive originals. Screen printing mainly uses positive pictures to make screens. Different plate making methods have different requirements for manuscripts.

　 Like other printing, silk-screen printing needs to accurately reproduce the image, text and tone of the original manuscript. In principle, the manuscripts used in screen printing are not very different from those used in other printing methods, but in specific plate making and printing practices, their requirements are different, which is mainly determined by the characteristics of screen printing. Especially due to the thick ink layer and bright color of screen printing, the special effects of screen printing should be fully considered when selecting manuscripts and plate making.

　　 In addition, the graphic lines and dot accuracy requirements of the manuscripts used in screen printing are also different from those of the manuscripts used in ordinary printing methods. If the lines and dots of the original manuscript are very fine, it is very difficult to use screen printing to make a plate. Therefore, the screen printing technology is not suitable for reproducing the original manuscripts with fine lines and dots. When choosing a printing method, it is necessary to fully consider the characteristics of various printing. Even in the screen printing plate making, the same attention should be paid to selecting the appropriate screen line in order to achieve the purpose of fully reproducing the original manuscript.
