These marks are usually seen in isolated areas and mainly caused by high curing temperature or substrate tensions. Here are some suggested ways to correct the problem: 1. Check that the substrate you are using is the same type as the one you have selected in the Internal Print Server. 2. Check that you are using the generic substrate preset for the substrate category. The use of incorrect values could cause incorrect substrate behavior. 3. Reload the substrate and try to minimize skew while loading. Check that you are loading the substrate using the correct procedure. 4. Try to reduce curing temperature and ink quantity if possible, and raise the curing airflow to help in reducing the substrate deformation. 270 Chapter 13 Troubleshoot substrate issues
