Gravure printing ink viscosity control and use

Release time: 2015-2-3

Gravure printing ink viscosity control and use:

Ink viscosity directly affect printing quality hue consistency, if improper control, can cause a large number of printing production of waste and the loss of raw materials. Therefore, should be reasonable control in the process of gravure printing ink viscosity. Usually adopt automatic control device to control the ink viscosity, viscosity or take to ink solvents, ink, the ink barrels, adding solvent drums, solvent delivery methods of pipelining, to compensate for the solvent evaporation on the influence of ink viscosity.

On energy type of ink and color ink, expensive special inks, ink tank volume smaller, should be taken to reduce the amount of residual ink; Take waste film package ink tank, in order to reduce the changing ink in the ink disk workload and solvent cleaning loss; Use the ink barrels to clean clean, will ink residues to minimize as much as possible.

The deployment of color gravure printing ink:

Allocate the color ink, in addition to the ratio of good records of all kinds of printing ink, also should be to return a moderate amount of ink. Printing again, to be in proportion to allocate the gravure printing ink, first by scraping the ink stick again, and repeat with the ink sample to do comparison, until no more visual appearance of the both color rear can use the computer printing. It can solve the ink to print color hue consistency between different batches. Conditional gravure enterprises will also be able to use the computer color matching and mixing system, in order to improve the ink color matching accuracy, reduced the remaining old ink in the ink library to a minimum.
