The influence of resin on ink properties

Resin used as the carrier of pigments in ink is the core material of ink, and its quality is good or bad This will directly affect the performance of the ink, as a good connection largely determines the viscosity of the ink To obtain high-quality ink, it is necessary to use properties such as viscosity, dryness, and fluidity High quality ink resin.

1. Adhesion fastness of ink

Resin connectors not only serve as a dispersing and wetting medium in ink, but also provide ink and base The most fundamental and important adhesion strength between materials is one of the most basic indicators of ink.

2. Coloring power of ink

The transparency of resin and the size of the color code directly affect the expression of color by different pigments The sufficient wetting and dispersion of pigments by resin directly affects the uniform coating of pigments by resin Sex can also affect the color of the ink itself.

3. Anti anti adhesive properties

Anti anti sticking is an important physical property indicator of printing ink. The resistance of ink to anti sticking is not only due to the complete evaporation of solvents during the printing process, but also to its dryness, It is also directly related to the film-forming and molecular properties of the resin connecting material used, and resins with good film-forming properties are connected The material can give the ink good dryness, and after the solvent evaporates and dries completely, the film is formed thoroughly and rolled up Excellent anti back adhesion.

4. Solubility

In gravure printing, ink solubility is also a key indicator for detecting the performance of ink, Especially in color ink printing, moderate solubility not only allows for full color display, but also makes it very effective Good solution to the problem of light mesh blocking and color mixing on the printing plate. Ink with poor solubility is not easily dissolved again by the ink in the ink tank, which can easily cause plate blocking accidents Ink with good properties is prone to being dissolved by oil and ink solvents in the printing plate, resulting in ink color mixing Problem.

5. Storage stability

Resin stability with balanced acid amine values, stored in a dry, ventilated, and cool warehouse to prevent damage and leakage Water ingress.
