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

    Författare :Erik Hallberg Hofstrand; Magnus Lestelius; Peter Rättö; Astrid Odeberg Glasenapp; D. Steven Keller; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Flexography; Corrugated board; Post-printing; Contact mechanics; Print quality; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    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.

  2. 2. Continuum Mechanics Modelling of Corrugated Board

    Författare :Ulf Nyman; Institutionen för byggvetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; assumed natural strain shell; failure criterion; lifetime; reliability; moisture transport; sorption hysteresis; corrugated board; hygro-elasticity; Materiallära; materialteknik;

    Sammanfattning : The storage of compressive loaded boxes in an environment with naturally varying humidity is a practical issue in corrugated board employment. Time dependent variables such as moisture content, strain fields, stress fields and material strength play important roles for the time to failure. LÄS MER

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

    Författare :Marcus Rehberger; Nils Enlund; Gunnar Engström; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    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

  5. 5. Print Quality of Post-Printed Corrugated Board

    Författare :Erik Hallberg Hofstrand; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Chemical Engineering; Kemiteknik;

    Sammanfattning : The use of printed corrugated board as a packaging material has evolved from a brown box with This Side Up stamped on it to an advertiser efficient in the customerÕs critical moment of purchase. The demand for quality printing of post-printed corrugated board is growing. LÄS MER
