Third, the paper causes dew: printing pattern deinking

The phenomenon of printing luster that occurs due to paper is mainly reflected in the deinking of the printed pattern. If the phenomenon of color lumps is mainly manifested in the middle part of the paper, the whiteness is serious. Because the paper is very poor in ink absorption, the ink cannot penetrate into the paper, and the ink floats on the surface of the paper. As long as the hand is used, the ink is detached.

Improvement methods: If you encounter this kind of printing and whitening, you should not add pressure and pressure to die. Be sure to work on the ink and increase the resin content and penetrant in the ink. This method is more effective than other methods.

Concluding Remark: The phenomenon of printing whitening and solving the problem of printing and dew-whiteness are far beyond these aspects. The above four types are just the most common phenomena of printing and whitening in the production process.
