  1. 1. 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.

    Sammanfattning : Popular Abstract in Swedish Wellpapp är ett populärt material i förpackningar för transport och lagring av konsumentvaror. Den viktigaste anledningen till dess popularitet är materialets höga styvhet och styrka, i förhållande till vikt och kostnad. Ingenjörsmässig användning av wellpapp kompliceras av många faktorer.

    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. Print Quality of Post-Printed Corrugated Board

    Detta är en avhandling från Karlstad : Karlstad University Studies

    Författare :Erik Hallberg Hofstrand; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

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

    Detta är en avhandling från Sundsvall : Mittuniversitetet

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