  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

  7. 5. Hybrid printing on fibre-based packaging : Performance, Quality and Market

    Author : Marcus Rehberger; Nils Enlund; Gunter Hübner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packaging; corrugated board; surface topography; print quality; variable data printing; hybrid printing; flexography; inkjet; print quality; market survey; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Variable data will play a decisive role in the future of packaging and product promotion. Variable data printing (VDP) is a technique whereby certain information can be altered in an otherwise static layout with the help of a digital printing system, and in the packaging industry a wide range of applications is possible.
