Causes of Bad Phenomenon Improvement Poor hue 1, Low ink viscosity
2, ink separation precipitation
3, the ink twisted too much to join the original ink ink tank shaking evenly relaxed twisting degree viscosity is too low 1, the foam generated
2, excessive dilution of water added to the defoamer added tackifier drying too slowly 1, the ink viscosity is too high
2, poor ink drying
3, paper, high humidity, poor absorption Dilution ink adjust the ink dry degree Replace the paper with good absorption Stacking ink 1, plate bad accuracy
2, the plate and roller contact pressure is too strong
3, the viscosity of the ink is too high to correct the layout height difference adjust the contact angle to adjust the viscosity to produce flash 1, the viscosity of the ink is too high
2, the ink drying speed is too fast
3. The contact pressure between the plate and the roller is too strong. Reduce the viscosity. Add slow-drying agent and adjust the degree of drying. High-speed contact angle.
2, the contact pressure is too strong
3, the viscosity of the ink is too high to adjust the height of the layout adjustment of the contact angle to adjust the viscosity of the paper transfer bad 1, insufficient printing pressure
2, the paper temperature is too high
3, drum wear, aging to increase the pressure of the dry paper to check the roller to produce foam 1, ink foam suppression and defoaming capacity is insufficient
2, the ink circulation is too large
3. The viscosity of the ink is too low. Additional defoamer reduces the amount of ink circulation. Appropriately increases the viscosity of the ink. Printing surface water 1. Low viscosity printing, coating volume is too thick
2, ink over-dilution plus the original ink added tackifier or replace the ink too dry 1. The ink is too dry
2, the plant temperature is too high to add slow-drying agent adjustment to strengthen the plant air conditioning appear spots 1, defoamer overdose
2, ink printing ink film is too thin
3, the viscosity of the ink is low, and the amount of the additive is added, and the amount of the additive is added to the original ink.
2, mixed with other ink
3, the preservation of the inappropriate use of special solvents should be confirmed prior to mixing closed secret version is not easy to clean 1, the ink is drying too fast
2, the version placed too long to use a slower dry ink to quickly clean the bad ink 1, the ink is too thick to convey
2, too much ink foam
3, circulation pipe leak
4, ink residue blocking pipeline dilute the ink into the defoamer, stirring evenly to repair the pipeline to eliminate the ink inside the tube plug version 1, ink flow is poor
2, the ink is drying too fast
3, ink mixed with paper powder and dust
4, ink viscosity is too high to replace the new ink to join the slow drying agent with 100 mesh copper mesh filter ink to reduce the viscosity dent phenomenon 1, printing plate uneven
2, paper thin corrugated uneven
3, poor operation of the plate cylinder
4, printing pressure is too small
5. The viscosity of the ink is too low to correct the height of the plate in the pad printing mode. Use a heavier series of paper to adjust the pressure of the plate roller and the roller to increase the viscosity of the ink.
