Problem: Stock is curling

 

Solutions:

Lightweight Stock (60-80lb text weight)

• Use stock of a higher grade or higher basis weight.
• Use inks that absorb less water.
• Use coatings that dry more quickly.

Stock Absorbing Too Much Water

• Apply less coating by adjusting application rate and/or reducing viscosity.
• Use inks that absorb less water.
• Use coatings that dry more quickly.

Stock Has Low Moisture Content

• Use stock with a moisture content of 5-6 percent. Low moisture stocks absorb more water.

Incorrect Humidity Levels In Pressroom

• Wrap loads or seal with plastic to keep sheets stable.

Mechanical Distortion From The Printing Process
