In the process of how to control the color printing aluminum foil packaging printing color copy
Many aluminum foil bag manufacturer know, during the process of production color printing aluminum foil bag printing, many variables influencing color printing aluminum foil bag printing image quality.
So, how to control in the process of color printing aluminum foil bag printing color copy?
Printing aluminum bag]
In order to better control in the process of color printing aluminum foil bag printing color copy, make up for the adverse effects of some variables, printing machine needs to adjust the three parameters: temperature, amount of ink and ink device and water supply.
Control in the process of color printing aluminum foil bag printing color copying, printing machine need adjustment lose some printing machine equipped with ink device temperature or optional ink device temperature control device.
In the process of the assumption, darting ink roller rotation and motion, thus raise the temperature of it the most, the temperature control, the general is in the channeling of ink roller core into the cooling water to reduce the temperature, make the ink roller surface temperature stable, thus ensuring the stability of the ink.
Some printing machine in addition to the channeling ink roller ink fountain roller zhongtong into the cooling water cooling.
Control in the process of color printing aluminum foil bag printing color copying, printing machine need to adjust the image surface printing ink quantity field size directly affect the quality copy color ink density, field size by the amount of ink (ink density
Printing images on the surface of the ink layer thickness)
As the ink layer thickness increase field density is increasing.
Arrived at some point after the field density will not increase with the increase of ink film thickness.
The quality of the article can be controlled according to the surface of printing image information to adjust the volume of ink (
Ink layer thickness)
The size of the.
Control in the process of color printing aluminum foil bag printing color copy, offset printing plate printing machine need to adjust the water supply of water size must be controlled.
Water size should be with printing machine printing speed varies, ink quantity, etc, to ensure that the ink balance, make the printing image hair flower, good color saturation, paste version.
Adjust water size is implemented by changing the water roller speed.
