  2. 1. Influence of Substrate Topography on Ink Distribution in Flexography

    Author : Gustavo Gil Barros; Per-Åke Johansson; Gunnar Engström; Magnus Lestelius; Patrice J. Mangin; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paperboard; topography; optical measurement; OptiTopo; flexography; flexo; print quality; printability; uncovered area; UCA; image analysis; frequency analysis; surface properties; paper properties; test equipment; measuring instrument; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : The printability of paper in flexography is largely dependent on the topographical characteristics of the substrate. Topography imaging instruments make it possible to obtain three-dimensional scans of paper surfaces that can be further used to calculate valuable quality parameters. READ MORE

  4. 2. Topographical micro-changes in corrugated board production : effects on flexographic post-print quality

    Author : Marcus Rehberger; Nils Enlund; Gunnar Engström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrugated board; liner; double-facer; double-backer; gloss; surface roughness; micro structure; wear; paper metal friction; flexo; ink-jet; print quality; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The appearance and design of a package are key properties to attract and to focus the attention of a customer. Print quality contributes to a great degree to achieve these requirements. Most critical perceived in terms of quality are print defects like mottling, gloss and stripiness, which all appear in the printing of corrugated board. READ MORE

  5. 3. Striping on flexo post-printed corrugated board

    Author : Martin Holmvall; Tetsu Uesaka; Joseph S Aspler; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : Striping is the most common print non-uniformity on corrugated board. It is defined as periodic print density and/or print gloss variations parallel to the flutes. Corrugated boards are mainly printed with flexography, making striping a major concern for the flexographic post-printing industry. READ MORE
