Flat Screen Printing Machine (Brief Introduction)


Screen printing was originally hand-spun, and a blanket was placed over a length of platform to cover the waterproof tape to make it easy to wash away. The longitudinal edges of the platen are each provided with a guide rail and an adjustable flower positioning device. When printing, the frame is laid down according to the positioning distance, and the color printing is formed by multiple frames according to the flower shape and the process characteristics, and the printing is repeated in a certain order (see color picture). A steam fin is installed under the platen or an infrared drying device is installed above the platen to make the fabric dry after being printed.

When a plurality of color pastes are overprinted, the contour of the pattern can be kept clean and prevented from permeating. The printing blade is made of rubber, and the angle, pressure and number of times of the blade during the squeegee are determined according to the process requirements. This printing method is characterized by less flower shape, color and fabric type restrictions, rich printing color, fine patterns, and is often used in high-grade textiles.

Manual scratching is labor intensive and requires skilled handling techniques, resulting in fully automatic mechanical squeegeeing. The automatic Flat Screen Printer machine usually has two types, one is the net motion type, the fabric is pasted on the surface of the long platen, and the screen printing machine with the screen runs on the track, automatically completing the positioning of the screen frame on the cloth surface and the lifting action controls the number of times the blade is scratched to ensure the accuracy of the printing.

The other is a cloth-type type, which is attached to a seamless annular rubber blanket, intermittently moved at equal distances according to the size of the printed frame, and the screen frame which is arranged in parallel on the cloth surface is simultaneously lowered or raised for scratching. This machine has a high production efficiency and a small footprint. The cloth Flat Screen Printing Machine can generally print 8 to 20 colors, and the size of the pattern can be adjusted, and the flexibility is large. However, since the color paste is wet after scratching, it has a certain influence on the printing effect of overprinting or overprinting.
