Step 3 Verify The Cylinder Plate Before Mass Production

After the plate making is completed, check and grind the plate before printing on the machine (to reduce the NG rate).

Step 4 Print

 In gravure printing, ink is applied to a cylinder plate, the excess is removed, and the remaining ink in recessed areas is transferred to the printing material under high pressure to imprint graphics and text

Step 5 Quality Inspection

The final printed product undergoes a quality check using a machine equipped with CCD to identify and remove any defective prints, ensuring high-quality output.

Step 6 Lamination

A high-speed dry laminating machine evenly applies adhesive across the non-heat sealable film.

Step 7 Slitting

Featuring advanced tension control and infrared edge alignment systems, the equipment can precisely cut materials to the customer's specified dimensions.
