  1. 1. Gravure vs. Web-offset! : a changing world in publication printing 1986-2006

    Författare :Anders Bjurstedt; Nils Enlund; Robert Chung; KTH; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Mass communication; Masskommunikation;

    Sammanfattning : The European publication printing industry and its markets have undergone profound structural changes between 1986 and 2006. This thesis is an investigation of these changes and of how the publication industry has been affected, as well as of the balance between publication gravure and commercial heat-set web-offset.

  2. 2. Delamination of paperboard related to offset printing

    Författare :Orlando Girlanda; Christer Fellers; Fredrik Thuvander; Jeffrey Suhling; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Mechanical properties; Delamination; Finite Element Method; Paperboard; Z direction strength; Test equipment; Paperboard; Sheet Offset Printing; Web Offset printing; Shear stress; Modelling; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Sammanfattning : The relationship between the behavior of paper during converting operations and the mechanical properties of paper are a fundamental issue for both paper producers and converters. In the attempt to establish these relationships and thus be able to judge the performance of paper, several testing methods have been developed. LÄS MER

  4. 4. Mechanics of paper webs in printing press applications

    Författare :Artem Kulachenko; Sören Östlund; Thomas Abrahamsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travelling webs; skew tension profiles; mixed dynamic formulation; fluting; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. LÄS MER

  5. 5. Analysis of the time and humidity-dependent mechanical behaviour of paper webs at offset printing preess conditions

    Författare :Jan Lif; KTH; []
    Nyckelord :creep; deformation; dynamic test; ;

    Sammanfattning : This thesis deals with the time, frequency andhumidity-dependent mechanical behaviour of paper webs at offsetprinting press conditions. How the paper web, the set-up andrunning conditions alter press performance is not fullyunderstood, and are difficult to isolate and investigateexperimentally. LÄS MER
