[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of printing, in particular to the technical field of a cooling roller device for digital color waterless offset printing for clothing labels.

[ background of the invention ]

Waterless offset printing uses an ink repellent silicone rubber layer as a blank part of a printing plate on a lithographic plate, does not need dampening, and is a lithographic printing mode of printing by special ink. Waterless offset printing uses a silicon coating on the printing plate as the non-printing area, removes the ink balance control, and also eliminates the use of water as the medium. From the viewpoint of print quality, printing without using water makes printing dots of waterless offset printing sharper and better perform. Waterless offset printing has the ability to achieve higher line counts and contrast.

Traditional printing machine needs moisture and printing ink cooperation to realize the print job, and waterless offset press then only need add specific printing ink can realize the print job, do not need additionally to add moisture again, this kind of printing machine receives favour day by day because it has better environmental protection performance, this kind of printing machine is because printing speed is fast, do not have the participation of water again in the printing process, so the surface temperature of ink distributing roller and plate cylinder can be very high, and after the temperature rises, the viscosity of printing ink can descend, and then take place dirty version trouble easily, and current chill roll cooling performance is relatively poor, the cooling efficiency is low, roller cooling reaction rate is slow, can not satisfy current waterless offset printing production demand.
