  2. 2. Flexographic Post-Printing of Corrugated Board : Contact Mechanics and Print Quality

    Detta är en avhandling från Fakulteten för teknik- och naturvetenskap

    Författare :Erik Hallberg Hofstrand; Karlstads universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Chemical Engineering; Kemiteknik; Flexography; Corrugated board; Post-printing; Contact mechanics; Print quality;

    Sammanfattning : As the corrugated board industry strives to produce products with a higher print quality in the converting stage, there is a need for a greater understanding of the factors influencing the final print quality and how we perceive the print. In this work, a method for quantifying the print quality of printed corrugated board is presented as well as methods that quantitatively characterize the mechanical interaction between the printing form and the corrugated board in the printing nip.

  3. 3. Topographical micro-changes in corrugated board production effects on flexographic post-print quality

    Detta är en avhandling från Stockholm : KTH

    Författare :Marcus Rehberger; KTH.; [2007]
    Nyckelord :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; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Sammanfattning : 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. LÄS MER

  4. 4. Interfacial Adhesion Failure Impact on print-coating surface defects

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Hajer Kamal Alm; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER

  5. 5. Benchmarking e-learning in higher education:Lessons learned from international projects

    Detta är en avhandling från Juvenes Print
