How to correctly use sublimation offset printing ink additives ?   FLYING FO-GA


Ink additives is a kind of auxiliary materials that used to adjust the ink to make it adapt to different printing condition. There are many kinds of printing ink additives, the following simple introduce common role of ink additives and their usage.     


3.Desiccant


Desiccant is one of very important printing ink additives. According to the printing conditions and printing paper are different, the amount of desiccant types and use methods are also different. Commonly desiccant have red dryness oil and white dryness oil. Red dryness oil is made from outer to inner in dry, white dryness oil is inner and outer in dry at the same time. When printing, in accordance with printing product that the require of dryness and ink color to choose which type of dryness oil. General dryness oil dosage is 2%-3%, too much will lead to just the opposite,bring down the drying speed.


4.Thinner


Thinner is heavy usage of ink additives in offset printing process. There are two common thinner: one kind of transparent oil for the high gloss offset printing ink, the other kind of resin type for resin ink. When ink color is too deep to restore the original in the printing process, that can add right amount from thinner to achieve the ideal effect.


5.Diluent


In printing process, ink viscosity is too large or paper quality is poor which can produce printing failure such as paper napping or filling up, to affect the printing on the rails. At this time, in addition to add the right amount of reducing viscosity solvent to reduce ink viscosity, also can add a small amount of diluent to reduce the viscosity of ink, to make the printing run smoothly. Many different kinds of diluent, usually for low viscosity of 6# varnish.


In addition to the above several ink additives, and also have retarder, overprinting varnish, antifoamer, gold tone oil and so on, so I won't go into much detail here, when used that can be operated according to use instruction strictly.
