Basics of Curl Problem Solving, 2001 Papermakers Conference Proceedings

Charles Green, James Atkins--Xerographic (laser) printing curl problems can be used as an example of how furnish, sheet formation, drying and the printing process all interact. By examining the reasons for curl we can take steps to improve it. By the use of good test methods we can minimize furnish coefficient of moisture expansion (CME) and adjust wire versus felt structure to be more alike. For laminates and board we need to make the structure of individual layers to be alike. We can adjust top to bottom drying to produce a flatter product. There needs to be a balance of wire and felt side coating or surface sizing. We also need to be careful of interactive effects between these inputs. Useful test methods are reviewed.
