Solvent ink common faults and countermeasures

Solvent ink common faults and countermeasures First, ink printing ink:
Paste phenomenon: the ink on the printing plate is dry and the pattern of the print is not clear.
Reasons: Countermeasures:
1 Ink drying too fast 1 Slow drying solvent added 2 Ink viscosity too large 2 Decreased ink viscosity 3 Printing speed too slow 3 Increase printing speed

Dirty, sticky phenomenon: The pattern of the printed product is contaminated, or the cause of adhesion between the prints: Countermeasures:
1The ink is drying too slowly 1Improve the dryness of the ink 2The ink viscosity is too large 2Impress the viscosity of the ink 3The printing speed is too fast 3Impress the speed of the printing machine

Frizz phenomenon: Friction on the edges of printed products Causes:
1 Inadequacy of ink viscosity control 1Adjustment of ink viscosity 2 Printing pressure is too large 2Adjust printing roller barrel 3 ink blade uneven 3 Replace the ink blade

Second, water-based ink paste version:
Symptoms: The ink on the plate is dry and the pattern of the print is not clear.
Reasons: Countermeasures:
1 Ink drying too fast 1 Slow drying solvent added 2 Ink viscosity too large 2 Decreased ink viscosity 3 Printing speed too slow 3 Increase printing speed
4 adjust the printing pressure

Dirty, sticky phenomenon: The pattern of the printed product is contaminated, or the cause of adhesion between the prints: Countermeasures:
1The ink dries too slowly 1Improve the dryness of the ink 2The viscosity of the ink is too large 2Impress the viscosity of the ink 3The speed of the printing machine is too fast 3Impress the printing machine speed 4Impression printing excess 4Fast printing pressure

The phenomenon of frizzy hair and beard: The causes of frizzy hair and beard on the edge of the printed product: Countermeasures:
1 Inadequate ink viscosity control 1Adjust the viscosity of the ink 2The dryness of the ink is too fast 2The dryness of the ink is reduced 3The pressure is too high 3Adjust the printing pressure

Bubble phenomenon: There are more bubbles in the ink tray. Causes: Countermeasures:
1 Ink pump causes 1 Adjust the ink pump 2 into the air 2 Add antifoam 3 Poor ink quality 3 Replace the ink

Third, the composite packaging ink paste version phenomenon: printing ink dry, unclear prints.
Reasons: Countermeasures:
1Ink drying too fast 1Add 3%-8% of drying agent 2Printer speed is not appropriate 2Adjust printing speed 3Printing viscosity is too large 3Adjust dilution solvent ratio

Electrostatic phenomena: Bearded, splattered, misted, or rounded shapes on the print.
Reasons: Countermeasures:
1 The viscosity is too low and the speed is too fast. 1 Increase the viscosity. Reduce the speed. 2. The ink concentration is too high. 2. Reduce the concentration. 3. Electrostatic effects. 3. Increase the static electricity inhibitor and isopropanol or ethanol.

Non-graphic phenomena Phenomenon: Leaking scraper to print Cause: Countermeasures:
1 Printing speed is too fast 1 Decrease the printing speed 2 The ink viscosity is too large 2 Adjust the diluent ratio 3 The ink re-solubility is poor 3 Add a small amount of butanone, toluene
