Abstract

The invention discloses a printing method for a plastic packaging bag. The printing method for the plastic packaging bag comprises the following steps of: mounting a plate cylinder; debugging a scraper; mixing a spot color; overprinting with a computer; checking a sample; printing; drying; winding into a roll; and curing, wherein a rolled plastic thin film is cured for 24 hours under a room temperature condition, so that ink is fully cured. By adopting the printing method for the plastic packaging bag disclosed by the technical scheme, the printing quality is high, a designed pattern can be truthfully reduced, printing preparation is quickened, carving production efficiency is increased, and the method is suitable for batch production.

Description

The printing process of plastic packaging bag

Technical field

The present invention relates to a kind of printing process of packaging bag, relate in particular to a kind of printing process of plastic packaging bag.

Background technology

Plastic packaging bag is seen everywhere in life, is indispensable articles for use in the life.Along with growth in the living standard, people are also more and more higher to the requirement of plastic packaging bag.The pattern of the packaging bag quality with printing quality whether attractive in appearance has influence on people to buying the product purpose in the packaging bag.

Summary of the invention

Goal of the invention: the objective of the invention is to the deficiency to prior art, provide a kind of printing quality good, can reduce the printing process of plastic packaging bag of designed patterns strictly according to the facts.

Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the present invention adopted is:

A kind of printing process of plastic packaging bag comprises the steps:

2), the debugging scraper, the debugging scraper makes scraper scrape printing ink, guarantees that the pattern of forme stores the China ink amount suitably;

3), transfer special look, reach the requirement of printing quality according to the color proportioning printing ink of printed patterns;

4), the computer chromatography, computer chromatography adjustment register control pattern guarantees printing quality;

5), check sample, pattern and the given pattern of sample that tentatively prints compared, guarantee that printed patterns is consistent with sample;

6), printing, carry out batch after check sample is qualified and print continuously;

7), oven dry, bake out temperature is 55 ℃～70 ℃, and the plastic sheeting after the printing through drying tunnel, and is carried out the air draft operation simultaneously, and printing ink is done rapidly;

8), twine rolling, carry out in rolling place of plastic sheeting, twine rolling;

9), solidify, the plastic sheeting of rolling was placed on room temperature condition under curing 24 hours, printing ink is solidified fully.

Beneficial effect: the present invention compared with prior art, its beneficial effect is:

1, order mounting cylinder has guaranteed printed patterns order partly, has accelerated printing and has prepared, and improves and carves production efficiency;

2, adopt this printing process, step is simple, and wherein has the step of check, and quality control is strict, has guaranteed that the packaging bag quality that prints is good;

3, be fit to large-scale production, improved production efficiency, reduced the printing cost of individual packaging bag.
