1. A basic requirement for perfect image reproduction is that the transparent negative of the positive image should be of good quality, that is, the edges of the dots should be neat and opaque. The color separator uses the same color mark as the printing ink used.
2．阳图底片放在玻璃板上，然后曝光，把绷好的网版放在阳图底片上，并与图像轴平行。如果出现龟纹，向左或向右旋转网版，直到龟纹消失，一般转7°即可,郑州印刷。容易形成龟纹的区域位于丝网网丝的方向上和丝网的交叉点上。主色和较暗的颜色引起龟纹的问题较多。
2. Place the negative on the glass plate and expose it. Place the tensioned screen on the negative and parallel to the image axis. If there is a tortoise print, rotate the screen to the left or right until the tortoise print disappears, usually turning 7 degrees, Zhengzhou Printing.

The screen frames used are all stretched with the same type and type of screen. Zhengzhou color printing. The use of dyed silk screen helps to eliminate the tortoise pattern. The tension of the screen plate should be uniform everywhere, and the tension of the four screen plates printed in four colors is the same.

If the angle of the scraper is too flat, the printing image may be blurred. If the angle is too steep, the risk of screen printing image distortion will be greater.
