Pre-Printed Printing Ink

The pre-printed printing ink produced by us can still maintain the gloss of the ink at high temperature, and can withstand temperature up to 180 ℃. At the same time, our pre-printed printing ink also has high wear resistance and wear resistance for more than 400 times. The organic solvent used is absolute ethanol, most of which is pure water, with low toxicity, little harm to human body and equipment and little pollution to the environment. Printing with pre-printing ink can realize complete machine printing and continuous production, and the obtained products have bright color and good saturation.

Our pre-printed printing ink products are made of high-grade imported environmental friendly acrylic resin, appropriate functional additives and various high-grade organic (or non organic) pigments through strict dispersion and grinding process. This series of inks are suitable for paper towel, coated paper, label flexographic printing and pre-printing high-precision printing with high temperature resistance, skid resistance and wear resistance requirements. After processing, they are mainly used for the outer packaging of FMCG food, medicine, electronics and other paper products.

Why is pre-printed Printing Ink environmentally friendly ink?

In people's eyes, pre-printed Printing Ink is environmentally friendly ink. But where is environmental protection?

Pre printed ink: pre printed ink consists of waterborne polymer emulsion, surfactant, pigment, water and other additives.

1. Waterborne polymer emulsion consists of acrylic acid and ethylbenzene. It is used as the carrier of pigment transmission, providing brightness, drying speed, adhesion, hardness, wear resistance and water resistance. Film forming emulsion is applied to the printing of non absorbent film on the surface of non absorbent substrates.

2. Surfactants reduce the surface tension, spread the ink on the substrate and improve the stability of ink.

3. Pigments: Organic phthalocyanine blue, lisol red; Inorganic carbon black, titanium dioxide.

4. Water solvent can change the viscosity of ink, which affects the thickness and drying speed of coated ink layer. pre-printed Printing Ink is different from solvent-based ink. The solvent-based ink is dissolved in organic solvents, such as toluene, ethyl acetate, ethanol, etc., while the pre-printed Printing Ink is dissolved in water and a small amount of alcohol (about 3% ~ 5%). Because water is used as the dissolving carrier, the pigment is.

Pre-printed Printing Ink is usually used for printing materials with holes and uncoated, such as paper and paperboard. It is also often used for direct mail products. It can be divided into pigment type and dye type. Pigments will precipitate because they cannot be dissolved in water. Therefore, the pigment should be ground very finely, which will have a better spray printing effect.

The pigment itself has good weather resistance, water fastness, light resistance and wear resistance; Dyes have good solubility, many kinds of colors and good brightness.

Advantages: harmless, safe, close to no volatile organic gas. It is mainly reflected in the following four aspects:

1. pre-printed Printing Ink has no pollution to the atmospheric environment;

2. Improve the safety of working environment and ensure the health of operators;

3. It can reduce the residue on the printing surface.
