Even if your customer is not currently complaining, poor roll edges may look like poor workmanship to your customer. No matter whether you have nearly laser-cut-looking roll edges or they are as ragged as a hedge, everyone can benefit from better-looking wound rolls. 

Roll edges are very much like the rings of a tree. Nearly everything you do on or upstream of the winder or everything in the tree’s environment leaves its mark.  However, while you might see a narrow tree ring as testament to a poor growing season, you don’t necessarily know whether it was caused by a season that was too hot, too cold, too wet, too dry, had bugs, had fungus or a dozen other factors.

​Roll edges are no less challenging to troubleshoot, but not impossible, but only if you are disciplined.
