PaperMap®

NON CONTACT PAPER SURFACE CHARACTERIZATION

The PaperMap® system offers non-contact high resolution measurement of paper, printed surfaces and fibrous materials. With a spot size less than a micron in diameter and a vertical resolution of only 3 nanometres, PaperMap®

accuracy is well beyond standard roughness analyzers in use so far. At the heart of the PaperMap®

system, the AltiSurfPaperMap workstation is composed of an optical sensor, a motion controller, translation stages and the PaperMap®

software. Ergonomically designed and user-friendly, the workstation can be used as well for laboratory investigation as for automated quality control. The workstation provides new tools, macros, parameters and work protocols

derived from existing projects and industrial implementations. PaperMap®

is optimized for the characterization and study of the microroughness of papers, boards, coatings, inks, varnishes and glues. It can be used to pinpoint problems linked to their support: coating blades, blankets, cylinders, offset plates and photogravure films. It is useful to characterize end-user properties: Texture, printability, coating potential, varnishing, transfer, porosity, weaving... These capabilities are also available on the side of production line and on-line. The PaperMap® solution is the perfect tool for the characterization of enduser quality needs in the paper, fibre and coating industries.
