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...

Abstract

The invention discloses a flexible printing process for corrugated cartons, relates to the technical field of flexible printing, and aims to solve the problems that performance of an existing flexibleprinting process for corrugated cartons is not perfect enough and the working efficiency is low. The process comprises the steps that S1, a plate cylinder is cleaned; S2, a base surface of a photosensitive resin plate is cleaned and dried by using a detergent; S3, a hard board double-sided adhesive tape is pasted to the plate cylinder; S4, a photosensitive resin plate printing plate is pasted onthe plate cylinder, and edge sealing is conducted by using a sealant; S5, an anilox roller is cleaned, and the plate cylinder and an anilox roller plate cylinder are installed separately; S6, a scraper blade is cleaned, and the scraper blade is mounted in a scraper chamber; S7, an ink box is cleaned, the ink box is installed, and then water-based ink is poured into the ink box; and S8, printing iscarried out on a corrugated board by a flexible printing machine.

Description

technical field [0001] The invention relates to the technical field of flexible printing, in particular to a flexible printing process for corrugated cartons. Background technique [0002] The flexographic printing process of corrugated boxes generally refers to a technology that uses flexographic printing for corrugated boxes. The printing method is flexographic printing. The printing plate generally adopts a photosensitive resin plate with a thickness of 1 to 5 mm. The ink is divided into three categories, namely water-based ink, alcohol-soluble ink, and UV ink. Since the ink used in flexographic printing is environmentally friendly, it has been It is widely used in food packaging printing and has a broad prospect. Flexographic printing belongs to the type of letterpress printing. Flexographic printing, offset printing, gravure printing and screen printing are the four most common printing methods in the world. They each have their own characteristics and advantages. In c...
