In our daily life, how can we control the printing of space bags, also known as bulk bags and tons of bags?

The colour of ton bags should be true, natural and colorful. The index should include two aspects: one is the field density tolerance of different sheets of the same batch of products, the green (C) magenta (M) is less than or equal to 0.15 black (BK) is less than 0.20, and the Yellow (Y) is less than 0.10;

Appearance is the first thing, layout must be clean, no obvious dirt; secondly, the color should be basically the same; that is, text, it should be complete, clear, accurate; finally, size requirements. The allowable error of fine product size is less than 0.5 mm, and the allowable error of general product size is less than 1.0 mm.

Of course, the printing quality of packaged bags depends on the following factors

First, personnel issues: personnel issues mainly reflect the sense of responsibility and technical proficiency of employees.

Secondly, equipment technology: aging of container bag equipment, drying and bagging technology will lead to various adhesion problems in the production process of container bags.

Third, the quality of raw materials: including ink quality, mixing uniformity, bag quality or offset printing problems will lead to printing problems.
