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

    University dissertation from Fakulteten för teknik- och naturvetenskap

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

    Abstract : 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

    University dissertation from Ulf Nyman, Structural Mechanics, Box 118, SE-221 00 Lund, Sweden

    Author : Ulf Nyman; Lund University.; Lunds universitet.; [2004]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : KTH

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

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

    University dissertation from Karlstad : Karlstad University Studies

    Author : Erik Hallberg Hofstrand; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : 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. READ MORE

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

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Martin Holmvall; Mittuniversitetet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP 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
