To count the five indicators of quality of offset printing ink

1.Saturation: Concentration of color that color saturation.

2.Overprint: Demand of newspaper printing to offset printing ink color basically has two, one is color series, 2 it is ink viscosity of degeneration.

3.Aridity: Ink drying speed will usually affect the printing quality, at the same time also can cause a lot of printing failures, such as lead to print on the back of the sticky dirty, even can cause paper rolls Printing from otherwise normal operations.

4.Optimum printing

5.Stability: For printing ink stability but also to the quality of printing quality.

There is great difference in ink coloration, environmental protection, and drying speed between domestic printing ink and imported ink, and domestic ink liquidity is not good, sticky Degree is bigger also, sometimes have to cancel the adherend. Wants printing ink viscosity can be improved and gradually replace the imported high-grade printing ink, a high price. Newspaper printing from printing Require effect of high viscosity of low viscosity, good ink transfer performance, especially the high speed printing machine for printing ink dry demand higher.
