Four in the plastic gravure printing ink printing use diluent formula, large scale exposure!

Four in the plastic gravure printing ink printing use diluent formula, large scale exposure! Four in the plastic gravure printing ink printing use diluent formula, large scale exposure!

plastic film printing are smooth and print are excellent, the preparation of the ink diluent is also very important, especially the intaglio printing. Gravure ink concentration ( Thick thin) Size, viscosity, directly affect the color difference of printing and printing pattern is clear, cause the printing rejection rate rise, even decides the speed of printing, so it's very important to ink thinner, the proportion of setting.
the different performance of ink to set different solvent mixture, then need according to the printing operation environment temperature, humidity, printing equipment, printing speed, print roller is different, for the preparation of the solvent ratio.
will be printed below room temperature at 20 ℃ or so, printing speed, in the case of 50 ~ 100 m/min, the four plastic gravure printing ink with diluent formula proportion and provide reference for gravure operator:
1, the ratio of the thinner plastic gravure printing ink used in:
quick-drying solvents: ethyl acetate 20%, toluene solvent: job
80% of 20% acetic acid, toluene 80% or 100%
slow dry solvents: ethyl acetate 20%, 80%
xylene ( Note: can't add alcohol solvent, add 5 - humidity climate 20% of butanone)

2, tables, plastic gravure printing ink use thinner proportion:
quick-drying solvents: 20% acetic acid, toluene was 40%, 40% isopropyl alcohol
dry solvents: 5% acetic acid, toluene was 55%, 40% isopropyl alcohol
slow dry solvents: 50% xylene, isopropyl alcohol 50%
slow dry solvents: 50% xylene, isopropyl alcohol, 50% n-butyl alcohol - 1 3%

3, alcohol soluble plastic gravure printing ink use thinner proportion:
quick-drying solvents: ethyl acetate 50%, anhydrous ethanol 50%
dry solvents: 20% acetic acid, isopropyl alcohol 80%
slow dry solvents: anhydrous ethanol 50%, propyl acetate 50%

4, cooking plastic gravure printing ink use thinner proportion:
quick drying solvent, 30% ethyl acetate, isopropyl alcohol 20%, butanone
50% dry solvents: 10% isopropyl alcohol, toluene was 40%, 50% butanone
slow dry solvents: 60% toluene and butanone, 35% propylene glycol methyl ether 5% packing printing knowledge conversion table
