In the pad printing ink is often considered as one of the key factors affecting the quality of printing.However, other factors are also important, often caused by other factors of the printer printing problems due to the ink, they sometimes can not solve the problem for hours, this is mainly because they ignore other variables, such as mechanical Settings, the influence of factors such as environmental conditions.So, printing to the pad printing process and the role of the ink completely clear, when problems occur, to consider that all factors affecting the quality of rather than looking for ink.
Specially for the pad printing ink is different from the general type of solvent ink, water-based ink and UV light curing screen printing ink.Although the pad printing inks and screen printing ink has some similar characteristics, but they still have very big difference.Different from screen printing ink, pad printing ink dry faster, this is also the most prominent feature of pad printing ink.At the same time, a lot of pad printing ink printed on the film, such use lead to pad printing ink is vulnerable to the effects of some factors such as temperature, humidity and electrostatic.
All pad printing ink contains connection material, paint, thinner, and some additives.Connection material is the main part of the ink, the typical connection material system with epoxy resin, vinyl resin and polyurethane resin type, etc.Pigment is powdered colorant, scattered in the connection of material, ink color and opaque.Thinner is mainly used to adjust the paint and connected to the material mixture viscosity, and the some of the ink to adjust the printing features.Assistant's role is to adjust the characteristics of the ink, such as liquidity and surface characteristics.
In order to ensure successful, pad printing ink must be good control, it must be able to in a short time fixation on the substrates.All in all, only the above list of all ink composition adjustment is good, the printing can achieve the best effect
