Adhesive printing process precautions

The printing staff first obtains the corresponding screen, ink, and adhesive materials according to the production subpena and process card requirements, and performs the mutual inspection work. Specifically, the printing personnel include: 1) The received screen printing plate, whether the ink meets production subpena or process card requirements. 2 screen quality meets the quality requirements for printing; 3 check the surface quality of the edges of adhesive materials. After the inspection is correct, fix the screen and adjust the net distance, and then use the positioning material for positioning. In this case, the position of the printing pattern must be determined according to the positioning frame. The three positioning pieces are located at 1/3 of each positioning edge. The size of the positioning piece is specified as 1cm × 2cm, and the position of the positioning piece at the edge of the adhesive material is marked when the original positioning is performed.

When transparent adhesive materials are printed, the body color test must be carried out. Only after passing the test can it be printed.

After the printing is completed, the self-adhesive printed on the ink such as Seiko Ink Co., Ltd. should be pushed into the drying room, the temperature is set to 45 to 50 °C, baked for 20 to 30 minutes, and then dried in the drying room; other types of ink After the printing is completed, the interior of the room can be naturally dried for 24 h before being stacked. Otherwise, it must be placed vertically. For two-color overprinting, the color registration interval should be controlled at 30 min or more. When collecting prints from the air baffle, it is necessary to ensure consistent positioning and no scratches or wrinkles; for non-conforming products, use the “×” mark on the bottom side of the paper to mark the corresponding part; Goods and non-conforming products, specify their respective quantities, and fill in the production.
