Commonly used sublimation offset ink additives are: reducing viscosity solvent, antioxidant, desiccant, thinner and diluent. This paper introduces five kinds of ink additives that the function and usage for you.
How to correctly use offset printing ink additives ? FLYING FO-SA
Ink additives is a kind of auxiliary materials that used to adjust the sublimation 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. SUBLIMATION OFFSET INKS
1.Reducing viscosity solvent
Reducing viscosity solvent has very little viscosity, commonly used for offset lithography in order to reduce its viscosity. In offset printing process, due to the change of the performance of paper and printing conditions, such as high oil-absorbing, poor surface strength, peeling coating of the front and back side of a phenomenon and when the desiccant excess or printing workshop at room temperature is too low, that all will cause failure which the paper napping, heap printing plate, paste plate, that affect the quality of the printing product. Therefore, when appear above phenomenon, can add right amount from reducing viscosity solvent, which can have the effect of abate and eliminate the above failure.
2.Antioxidant
Antioxidant is a printing ink additives as opposed to desiccant. In the printing process, due to various reasons will make the machine unusable, when stop for a long time, ink will dry and scab at the machine. In order to solve the problems, commonly add right amount from antioxidant in the ink and run machine several times, make it not dry too fast.
Hope these informations are useful for you and your customer.
