- The furrows and recesses of papers are called scars.
- The scarredness as cause for problems in painting, coating, printing, clogging and laminating has scarcely been investigated and noticed yet as well as its influence on the surface quality.
- Scars occur at the production process in the paper machine inter alia as a print of the covers made by wires and felts. Possibly they are shaped decisively by the press of the felts in the press section.
- Bigger pores and recesses in the felt result in material accumulation on pressing. Those protrude as pinnacles from the plane of the sheet after the separation from felt and paper surface. By contact with rollers, drying cylinders, calenders etc. under compulsion they are leveled and compacted.
- Extreme scars are causes for missing dots and missing dye transfer in the offset.
- Scarredness reduces the color transmission. On the decor print the relationship between scarredness and print quality has been proven doubtless.
