Screen printing ink is an essential colorant in the printing process, without ink to add color to the product, printing will lose its significance. So, do you know what are the ingredients in screen printing ink?
Colorful colors give the world a lot of beauty, and these colors can also be used in printing technology to draw a series of beautiful patterns. What are the ingredients in the screen printing ink that can make the pigment stick to the substrate?
1. Binder: it is a kind of liquid glue, which can stick the pigment on the substrate, playing a very obvious decorative role. Through the binder, we can also see the viscosity, drying speed and flow performance of the ink. The binder must be of high quality. The main component of the binder is vegetable oil or mineral oil, and the resin is also indispensable.

2. Pigment: pigment is actually a kind of colored solid substance, which is difficult to dissolve in water and insoluble with binder.

3. Auxiliaries: from the literal meaning to understand, in fact, is to help ink better play a role. Screen printing ink can make the performance of ink better. For example, plasticizers increase the plasticity of the ink, enhance the softness of the ink; Diluent makes ink thinner, so that ink has better liquidity; Remove adhesive can make the viscosity of the ink smaller; Drier is also called desiccant, ink can accelerate drying.
The quality of screen printing ink is directly related to the quality of the printed matter itself. Therefore, we have to pay attention to this point. Choosing the right ink is the key to the success of printing.
