2. 1. Laboratory method for the study of moisture-induced waviness in paper

   Author : Cecilia Land; Göran Ström; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; method; moisture; paper; paper web; wavelength; waviness; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Abstract : Paper that is subjected to moisture undergoes dimensional changes. It expands during moistening and shrinks during drying. When the paper is under tension between rollers, the effects are complex since shrinkage and expansion are restricted in the width direction. Waves can then appear on the paper web. READ MORE

4. 2. Ink film splitting acoustics and tack on paper in offset printing

   Author : Joakim Voltaire; KTH; []
   Keywords : Ink film splitting; tack; offset; printing; ink setting; coated paper;

   Abstract : This licentiate thesis comprises two complementary studiesdealing with the sheet-fed offset printing of paper. The firststudy addresses the further development of a practical methodto acoustically monitor and analyse the film splitting ofoffset inks. READ MORE

5. 3. Toward better image reproduction in offset

   Author : Emmi Enoksson; Nils Enlund; Ulf Lindqvist; KTH; []

6. 4. Delamination of paperboard related to offset printing

   Author : Orlando Girlanda; Christer Fellers; Fredrik Thuvander; Jeffrey Suhling; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

   Abstract : 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. READ MORE

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

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

   Abstract : 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.
