CH paper gravure ink

CH gravure printing ink is a paper gravure ink with cellulose as the substrate and ester and alcohol as main solvents. It is suitable for general commercial gravure printing machine. For different printing speeds, the printing effect is very clear; The substrates have excellent printing effects.

First, performance:

a, good color, bright colors, clear and distinct.

b, not easy to stick, not easy to scratch, wear rub.

c, no odor, non-toxic, good solvent release, excellent high-speed printability.

d, chemical resistance, acid and alkali resistance, water resistance, strong frost resistance, good adhesion.

e. Excellent post-printing processability (bronzing, etc.).

f. Adherence to the company's paper gravure varnish products is excellent.

Second, the substrate:

CH gravure printing ink is suitable for all kinds of paper gravure printing, such as coated paper, white cardboard, white paper, purified metal film and metal laminating products.

Third, product specifications:

1. Viscosity: Zahn #3/25°C 30-50 seconds

2. Fineness: ≦5um

3. Initial dryness: 40-70mm

4. Frost resistance: ≦4°C

5. Adhesion: ≧98%

Fourth, deployment operations:

The main solvents for gravure inks are alcohols and esters. The following mixture is very suitable for CH gravure ink preparation and dilution at printing speeds from 100m/min to 200m/min.

A, ethyl acetate: ethanol (isopropanol): toluene

1 : 1 : 1

Or Ethyl Acetate: Ethanol (Isopropanol)

1 : 1

When used as a dilution, please mix a variety of solvents into the ink.

B. The amount of ink thinner varies depending on factors such as the printing speed, the amount of dilution is too large, the dried ink film is thin, and the abrasion strength and wear resistance are weakened. The general ratio of diluent and ink is 0.2. -0.5:1.

C. The color concentration of this series of products is high. If you want to reduce the ink color concentration when using, please use our company's CHM diluting agent.

V. Viscosity:

The printing viscosity varies according to factors such as printing speed and printing conditions, and is generally 18-25 seconds at an Indian speed of 80-150 m/min at Zahn cup No. 3 at 25°C.

Sixth, use instructions:

When the ink is used, an appropriate amount of thinner must be added, and the company's standard thinner can be used to obtain the best printing effect. The company has fast, slow, dry diluents to choose from, to adapt to different climates and printing speeds. The use of an inappropriate diluent can destroy the properties of the ink, such as gloss, color, and the like.
