Tips for using water-based ink:
1.Do not mix ink with solvent ink.In the use of appropriate water, really need to adjust the viscosity or drying speed, an appropriate amount of alcohol or esters and other additives.
2.Before use should stir evenly and then into the ink tank, water appropriate viscosity adjustment, can be used.Unused should cover the barrel, do not let the ink in nature volatile.
3.Before use should test the technical indicators, especially whether the hue is in line with their own requirements, if the hue deviation is large, please inform the water-based ink manufacturers for appropriate deployment, so as to avoid the hue error caused by disputes between the two sides.
4.During the printing process, the original viscosity and PH value of the ink will be affected due to the evaporation of water. The viscosity and PH value need to be tested frequently. When necessary, pure tap water or PH stabilizer should be added appropriately.
5.The ink left on the printing equipment after printing shall be rinsed with water.
The ink on the anilox roller of the printing machine is best cleaned with detergent for next printing.Out of the water-based ink using errors and not all gravure water-based paper ink users are aware of the principle of viscosity, a lot of people will have such a misunderstanding, that ink viscosity is good ink.Can add a lot of water, printing more cartons, reduce costs, improve efficiency.In fact, not according to the performance of production equipment, blindly buy high-grade ink, think that with high-grade ink can print good quality prints, this is very unrealistic, unscientific.The most simple test standard of high-grade ink is the existence of color, but that does not lose color ink is high-grade, or that high-grade ink is not lost color, is not particularly accurate.In the case of no impact on the printing speed, as far as possible in the printing process of ink drying speed diffuse printing tools.It can also be adjusted by adding desiccant.Different manufacturers of ink to join the amount of drying agent, generally not more than 5%.Ink will thicken and pH will reduce the printing tool.
