Recently, the ink has aroused great concern in the industry. In order to better use of ink, enterprises should understand that the different requirements for the roll of water-based and solvent based inks. 

1, the ink roll precision, smoothness, plating has higher requirements 

Most of the time due to the ink dry slowly, transfer good, shallow and net hole depth of the version, this version of the accuracy requirement is not high, ink layer could not conceal the defects in the version of the body, such as common some cars pattern "and" washboard "problems are caused. 

Version of the surface finish is not high, ink is not easy to clean - shaven, due to the ink transfer is excellent, the scraper scratch after attachment in drum gravure surface ink easily transferred to the printing substrate, will lead to prints hang dirty. So often have to increase the blade pressure, if the chrome roll surface layer hardness is not enough, the service life will be shortened. 

2, height, depth and gradient and solvent ink printing darkened parts are of great difference 

Water-based ink transfer, good reproduction of shallow network is particularly prominent. Net point in gravure ink from scratch after scraper to viscosity change is not obvious transfer between outlets can easily complete reproduction. At this point, if the version and carving parameters still according to the traditional solvent printing ink set, then it is easy to cause high, darkened hiberarchy contrast polarity greatly weakened and often attend. This requires seihan will steepen gradients some, the darkened parts of these slightly darker, intermediate to high-profile positions, light some, only take into account this, high-profile, darkened gradient to perfect reproduction. 

3, the degree of expansion of the dot is larger than solvent ink 

Generally speaking, ink printing viscosity is low, dry slowly, in addition to the ink with all kinds of additives and alcohol to help solvent, resulting in the printing pattern of lines, writing extended serious. In printing pattern lines becomes rough, sharp blunt, Yang words change, anti word yin becomes small, illegible, barcode scanning through however, resulting in waste. So we should take full account of this in the plate making, the line will be properly reduced some.
