1. One of the basic requirements for perfect image reproduction is that the quality of the transparent positive film is good, that is, the edges of the points should be neat and opaque. In addition, the color analyzer and the ink should use the same color code.

2. Place the positive film of the led acrylic display box on the glass plate, and then expose. Place the stretched screen on the positive film and parallel to the image axis.If the Moire fringe appears, rotate the screen left or right until the Moire fringe disappears. The areas that are prone to ripple are located in the screen and where the screen intersects. The dominant and darker colors cause  lot of Moire problems.

3. Four-color printing, using the same size and stability of the aluminum frame, and the frame used are the same kind and model of screen stretching. The use of dyeing screen helps to eliminate tortoiseshells, with even tension of screen parts, and consistent four-color printing screen tension.

4. Polished scrapers are important for high quality printing, and the Shore hardness of the blade bar should be about 70. In addition, the scraper should be set at a 75 degree angle. Because if the scraper angle is too flat, the printed image may be blurred. And id the angle is too steep, there is a great risk of distortion in the screen printing image.

In order to control the stain of UV ink when color overprinting, it is recommended to print in the order of blue, magenta, yellow and black. When using UV ink, the screen thickness should not exceed 5um.
