Selection screen printing screen frame
The screen printing frame is divided into aluminum alloy profile and steel net frame, and the elasticity coefficient of steel is 2.9 times times of aluminum, the screen that requires very high tension wants to use steel net frame. For example, disc screen printing with the screen, the tension for the 22-26n/cm, and the requirements of the section is small, so it is to use about 3mm of steel plate making mesh box, so in the four-color screen production and printing process in the same position, overprint accuracy, hue good, not easy to produce moire and so on.
For the position and Screen Printing Aluminum Frame, you must do a few pieces of mesh frame material, size, tension and network of the strain and screen tailoring direction.
Screen Printing Frames size and the size of the printed graphics is not suitable, will affect the printing accuracy and screen tension stability. To this end, the general requirements of the screen frame is printed on the four edges of the screen frame at least 15CM, small and medium-sized size and network framed for 10CM, requiring higher precision, printed graphics long, wide size should be the frame of the screen frame long, wide size of 1/3.
