What are the common problems encountered in food bag printing?

(1) ink fluidity is not good
Causes: printing ink drying too fast; High viscosity of surface layer; It's bad to find fault.
Solution: apply slow drying solvents; Dilution with solvent for gravity; (3) in the ink.
 
(2) magnetic ink
Causes: printing ink viscosity is too low; Ink drying too fast; Slow printing speed; Ink quality problems. •
Solution: residues increase viscosity and reduce diluent. Gravity USES a slow drying solvent; Speed up printing; Replace ink.

(3) poor drying

Cause: less drying agent in the printing ink; Overdosage of gravity using slow drying solvent; Drying time and temperature deficiency; I have problems with ink quality.
Solution: increase the amount of drying agent; Reducing the amount of slow drying solvent in air. Increase drying time and temperature; Replace ink.

(4) stick
Causes: ink drying is too slow; Air drying temperature and time shortage; The materials of the printer brush are not properly kept; High temperature or compression.
Solution: use quick-drying ink. Air temperature is raised to increase drying time. Improve storage to prevent compression and reduce room temperature.

(5) through printed
Cause: poor ink itself; The solvent used in the solvent was wrong. Poor substrate.
Solutions. Gravity USES a specified solvent; Replace substrate.

(6) the stink
Causes: excessive drying; Solvent containing stench; The bad oil smells bad by itself.
