Offset printing ink's features

Time: 2018-08-09

The main features of offset printing are as follows:

1. ink layer thickness is very thin, general offset ink monochrome thickness is about 2 m.

2. Because the ink roll and water roll contact with the plate alternately, so the ink printing ability requirements are very high, and at the same time to prevent ink emulsification.

3. Offset printing speed is fast, usually in 100~400m/min.

4. Offset printing ink has high viscosity, high pigment concentration and also high coloring power.

5. Offset printing is indirect printing, it is transferred from elastic rubber roll to print, so the printing pressure is small and uniform, the precision of the printing is high, the reproduction of the graphic is good, the dot is clear and the level is plump.
