As an environmentally friendly ink, high-temperature water-based inks contain very little organic solvents except for a very small amount of additives, and there is no problem of VOC emissions
How to eliminate the burrs of printed pictures?
The flash phenomenon in high-temperature water-based ink printing is because the ink itself is too dry and the printing speed is too slow.
Sometimes "double eyelids" can be mistaken for burrs, and "double eyelids" are formed by excessive printing pressure.
How to prevent ghost images during printing?
The ghosting phenomenon in the printing process is related to the printing color sequence, the viscosity and adhesion of the ink, and the printing pressure and printing speed.
How to prevent pinholes from appearing on the printed product?
The pinhole phenomenon is manifested as the uniform distribution of white dots on the entire printed picture
What effect does the fast or slow drying of the ink have on the print quality?
Take out the product that has just been printed and touch the surface of the printing ink layer lightly.
The high-temperature water-based ink dries too fast, the screen printing pictures quickly show a paste phenomenon, and the margins of the solid-printed pictures will appear burr-like.
If the drying speed of high-temperature water-based inks is too slow, the overprinting effect is not real, and smearing is easy to occur
How to keep the ink color of the printed pictures stable?
During the printing process, the ink color of the printed product should be kept unchanged.
How to ensure the best overprinting effect?
To ensure the best overprinting effect during the printing process, a reasonable printing color sequence must be set and the principle of decreasing ink viscosity must be followed.
At the same time, the printing pressure must be moderate, not too large or too small
.
How to deal with the problem of poor ink leveling during printing?
If the ink leveling is not good during printing, in addition to adjusting the ink viscosity and increasing the leveling agent, the following solutions can also be tested
.
(1) Check whether the coating on the surface of the glass is not conducive to ink spreading;
(2) Replace the anilox roller with larger ink capacity;
(3) Check whether recycled ink is used, and test using brand new ink;
(4) Require ink suppliers to supply inks with better leveling properties
