1, the printing effect control
General four-color water-based ink is not bright, gray and the concentration is not high and other disadvantages. Used in the Indian can be achieved in the text clear, complete network, hair color strong, structured and other advantages.

2, appropriate shallow version
Four-color water-based ink has a Newtonian fluid rheological characteristics, more than 15% of solvent-based ink; four-color water-based ink solid content is high, the same area drying ink film thickness can be thinner. Compared to ordinary ink can achieve the purpose of ink.

3, the use of defoamers
As the four-color water-based ink is alkaline, in the printing process more prone to air bubbles, affecting the quality of printed materials, you can add about 0.1% of the defoamer to adjust.

4, dry temperature control
Four-color water-based ink printing process will appear, and with the reaction of dry, dry ink film complex solution than the solvent-based ink is poor, so the air temperature control is very important, the air temperature of the printing drying speed have a certain impact. The temperature is too low ink surface dry knot, but the internal dry impermeable, when the color appears anti-stick; temperature is too high ink drying too fast, dry kneading ink can not be dissolved in water, cleaning difficult.

5, can not mix
Four-color water-based ink can not be mixed with other solvent-based ink, or easy to affect the quality of printed materials.

6, PH value of the control
As the four-color ink in the printing of the volatile so that PH changes can be added in the printing process to adjust the corresponding additives.
