Research of the factor that influence the ink printing density of water-based gravure ink

摘要

Ink printing density decides the quality of the printing.The content of resin type and additives,ink fineness and the content of primary inks were changed to improve the quality of the water-based gravure ink.Then use the proof machine of gravure to make a proof and test the printing density of the proofs.The influence factors of water-based gravure ink printing density were studied and the research shows that the ink printing density increases first,then decreases with increasing the content of the primary ink; the ink printing density increases with the ink fineness improvements; different kinds of resin has difference influence on the ink printing density; the ink printing density increases with increasing the content of resin; addition of an effective anxiliary can improve the ink printing density.
