How to dilute ink?

If it is offset printing ink, then add ink oil on the line, the amount is less than 5%, used to dilute offset printing ink;

In caseScreen printing inkThen add diluent on the line, the increase refers to the actual ink viscosity and the viscosity requirements that need to be printed, as appropriate.

Surface printing ink manufacturers explain how much ink and ink thinner (formula) ratio is appropriate
First of all, different performance of the ink to set a different solvent mix, followed by the need to print the operation of the ambient temperature, humidity, printing equipment, printing speed, printing roller, formulate the proportion of solvent preparation.

The following printing room temperature is about 20 ° C, the printing speed is 50 ~ 100 m/min, plastic gravure four kinds of ink printing diluent formula and proportion to provide gravure operators reference:

1, the ratio of diluent used in plastic gravure ink:

Quick drying solvent: ethyl acetate 20%, toluene 80%

Medium dry solvent: ethyl acetate 20%, toluene 80% or 100%

Slow drying solvent: ethyl acetate 20%, xylene 80%

(Note: alcohol solvent cannot be added, 5-20% butyl ketone is added when the climate humidity is high)

2, the ratio of diluent used in surface printing plastic gravure ink:

Quick drying solvent: ethyl acetate 20%, toluene 40%, isopropyl alcohol 40%

Medium dry solvent: ethyl acetate 5%, toluene 55%, isopropyl alcohol 40%

Slow drying solvent: xylene 50%, isopropyl alcohol 50%

Super slow drying solvent: xylene 50%, isopropyl alcohol 50%, n-butanol 1-3%

3, the proportion of diluent used in alcohol-soluble plastic gravure ink:

Fast drying solvent: ethyl acetate 50%, anhydrous ethanol 50%

Medium dry solvent: ethyl acetate 20%, isopropyl alcohol 80%

Slow drying solvent: anhydrous ethanol 50%, propyl acetate 50%

4, the proportion of diluent used in cooking plastic gravure ink:

Fast drying solvent: ethyl acetate 30%, isopropyl alcohol 20%, butyl ketone 50%

Medium dry solvent: isopropyl alcohol 10%, toluene 40%, butyl ketone 50%

Slow drying solvent: toluene 60%, butanone 35%, propylene glycol methyl ether 5%

Screen screen with what ink and thinner?
Screen printing ink generally requires a little viscosity, the ink is not easy to draw.

The components of ink are pigments, resins, fillers, additives. There are many solvents for diluting ink, and you can choose the speed of volatilization, but you must consider environmental protection. The solvent evaporates quickly, the ink dries quickly, and the solvent uses alcohol.
