Problem: Coating dries too slowly

 

Solutions:

Pressroom Heat/Humidity Too High

• Adjust environmental controls in pressroom.
• We recommend 72F and 40% relative humidity.

Equipment Not Functioning At Optimum Settings For Job

• Check performance of drying equipment: hot air knives, exhaust, and IR lamps.

Stock Has A High Moisture Content

• Use stock with a moisture content of 5-6 percent.

Applied Coating Film Is Too Thick Or Heavy

• Apply less coating. Adjust application ratre and/or reduce the viscosity.
• Check stripe between metering and applicating rollers.
• Check coating weight and mileage for proper applied coating thickness.

Heavy Ink Coverage

• Use faster setting ink.
• Use a strong ink, so you need to carry less.
• Remember, a heavy 4-process job dries more slowly than light screen work.
• Check with supplies for faster drying or specialized inks and coatings.

Stock Is Nonporous (high holdout)

• Use fast drying inks and coatings.
• Use ink designed for substrate.
• Check with supplies for more compatible inks and coatings for stock.

Ink Picks Up Water (emulsifies)

• Ensure that ink is not contaminated.
• Use a high solid ink.
• Ensure that coatings and inks are compatible.

Incorrect Coating Used

• If all other causes have been addressed, consult Nicoat.
