  1. 11. The Influence of Moisture, Temperature, Pressure Pulse and Substrate on Print Quality in Flexographic Printing

    Författare :Johanna Johnson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Flexographic printing is a common printing method for package printing. It is primarily the flexible printing plate and the low viscosity inks that characterizes flexographic printing, and make it possible to print on a variety of substrates. One drawback of flexographic printing has been limited print quality. LÄS MER

  2. 12. Some aspects on flexographic ink-paper and paperboard coating interaction

    Författare :Robert Olsson; Magnus Lestelius; Li Yang; Jan van Stam; Timothy C. Claypole; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Ink; Coating; Paperboard; Printing; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Flexographic printing is a process that employs a flexible printing form and low viscous ink, often water-based. The flexible printing form is favourable for printing on rough surfaces, but the high surface tension of the ink may cause printability problems. LÄS MER

  3. 13. Absorption non-uniformity characterisation and its impact on flexographic ink distribution of coated packaging boards

    Författare :Sofia Thorman; Li Yang; Göran Ström; Magnus Lestelius; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid absorption; Absorption non-uniformity; Characterisation; Measurement technique; Print Mottle; Flexography; Coated packaging boards; Chemical Engineering; Kemiteknik;

    Sammanfattning : There are high demands on flexographic print quality to be sufficiently high and consistent in order to create a competitive packaging. At the same time the production efficiency need to be high. Printers thus need to achieve the same quality every time and quickly start-up new printing jobs. LÄS MER

  4. 14. Striping on flexo post-printed corrugated board

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

    Sammanfattning : 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. LÄS MER

  5. 15. Influence of Substrate Topography on Ink Distribution in Flexography

    Författare :Gustavo Gil Barros; Per-Åke Johansson; Gunnar Engström; Magnus Lestelius; Patrice J. Mangin; Karlstads universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
