  2. 1. Projective methods and longitudinal developmental research : considerations of data's nature and reliability

    Author : Harald Janson; Bertil Mårdberg; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Longitudinal studies; projective methods; reliability; temporal stability; interrater agreement; epistemology; measurement; psykologi; Psychology;

    Abstract : A projective method is viewed in the present work as a psychological test, by which is understood a standardized task that is set before a person, the solution of which is used for making inferences about psychological quantities. The present research was designed to shed light on several aspects of the usefulness of projective methods in longitudinal research, particularly with regard to reliability and to the distinction between measurement and theory-free empirical-comparison data.

  5. 3. New methods for evaluation of tissue creping and the importance of coating, paper and adhesion

    Author : Jonna Boudreau; Christophe Barbier; Ulf Germgård; Sverker Albertsson; Robert Pelton; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue; creping; paper adhesion; Tissue paper; creping; paper adhesion; coating layer; adhesives; Yankee cylinder; crepe structure; wavelength measurements; Chemical Engineering; Kemiteknik;

    Abstract : The creping process and the conditions on the Yankee cylinder dryer are key factors in a tissue paper mill, and they therefore need to be kept under good control in order to maintain a high and uniform quality. To this end it would be valuable to be able to make on-line measurements of Yankee coating thickness as well as the crepe structure of the tissue paper. READ MORE

  6. 4. Influence of Substrate Topography on Ink Distribution in Flexography

    Author : Gustavo Gil Barros; Per-Åke Johansson; Gunnar Engström; Magnus Lestelius; Patrice J. Mangin; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paperboard; topography; optical measurement; OptiTopo; flexography; flexo; print quality; printability; uncovered area; UCA; image analysis; frequency analysis; surface properties; paper properties; test equipment; measuring instrument; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : The printability of paper in flexography is largely dependent on the topographical characteristics of the substrate. Topography imaging instruments make it possible to obtain three-dimensional scans of paper surfaces that can be further used to calculate valuable quality parameters. READ MORE

  7. 5. Aspects of Flexographic Print Quality and Relationship to some Printing Parameters

    Author : Johanna Johnson; Lars Järnström; Magnus Lestelius; Peter Rättö; Erik Blohm; Jouko Peltonen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Print Quality; Liner; Board; Newsprint; Water-borne ink; Dynamic Pressure; Plate Properties; Wetting; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : Flexographic printing is a common printing method in the packaging field. The printing method is characterized primarily by the flexible printing plate and the low viscosity inks which make it suitable for use on almost any substrate. READ MORE
