The advantages of waterless printing summary and difficulty 3

The advantages of waterless printing:

Reproducibility of dots Good consistency of ink reproducibility Reproducibility of dot gain Small overlay Accurate printing plate Printing fastness High gloss Good printing Fast printing High efficiency Operational convenience Material saving Reduce environmental pollution

Waterless printing technology difficulties:

1. Waterless offset printing requires a special plate "target="_blank"> Plate material This is the centerpiece of waterless offset printing technology. It is necessary to develop a special plate that can repel ink in non-graphic parts.

2. Need special ink to develop soft, neutral, hard and UV hardened waterless printing oil.
