Embodiment 1
[0024] A corrugated box flexible printing process, comprising the following steps:
[0025] Step 1. Prepare the pre-installed printing plate cylinder first, clean the ink and impurities on the surface of the printing plate cylinder with detergent, and wipe the detergent on the printing plate cylinder with a non-toxic cloth after cleaning;
[0026] Step 2, cleaning the oil stain and photopolymer residue on the base surface of the photosensitive resin plate with a detergent, and then drying the base surface of the photosensitive resin plate with a dryer;
[0027] Step 3. Select the double-sided adhesive tape of the hard board that is larger than the printing plate of the photosensitive resin plate. First remove part of the protective film on one side of the double-sided tape. After a part of the tape is fixed, then gradually open the protective film. Apply the tape to the plate cylinder;
[0028] Step 4. Paste the printing plate of the photosensitive resin plate on the tape of ...
Embodiment 2
[0035]The rest of the steps are the same as in Example 1, wherein the temperature of the dryer in step 2 is set at 55°C, when the base surface of the photosensitive resin plate is completely dried, and then the base surface of the photosensitive resin plate is completely wiped clean with a non-woven cloth, the steps In step 3, use a soft roller to roll the tape evenly and firmly. The rolling method is to compact it in a "herringbone" shape from the middle to both sides, so that the air in the middle of the tape can be squeezed out. Step 5 The middle anilox roller is specifically a ceramic metal anilox roller. The anilox roller is immersed in an ultrasonic cleaning tank filled with detergent. Work, make the solution vibrate to generate bubbles to cause inward explosion, continuous inward explosive force, expel the ink from the mesh, and flow away with the cleaning liquid, set the cleaning time to 19 minutes, and accurately position the scraper and sealing knife in step 6 , depe...
