Three Important Printing Quality Indicators for Coated Paper

Coated paper is a kind of advanced printing paper. When buying coated paper, not only the mechanical parameters of the paper should be noticed, but also its printing quality parameters should be fully noted.

1. Ink Absorption: This is a more important indicator of coated paper. Mainly in the strength of ink absorption and the uniformity of ink absorption. The strong ink absorption of the paper will cause poor printing gloss and increase the amount of ink consumed for printing. The paper will suffer from poor ink absorption and make the printed items sticky. The paper ink will absorb unevenly, and prints will be apt to produce spots, stripes, etc.

2. Gloss: Gloss is divided into paper glossiness and printing glossiness, and it is also the main quality index of coated paper.

3. Chromatic aberration, although there is no paper color difference indicator in the technical index, the influence of color difference on the quality of printed matter is relatively large.
