  1. 1. Using Multicoloured Halftone Screens for Offset Print Quality Monitoring

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Lars Bergman; Högskolan i Halmstad.; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multicolour printing; Printing process; Colour images; Colour impression; CCD-camera; TECHNOLOGY Information technology Computer engineering; TEKNIKVETENSKAP Informationsteknik Datorteknik; multicolour printing; printing process; colour images; colour impression;

    Abstract : In the newspaper printing industry, offset is the dominating printing method and the use of multicolour printing has increased rapidly in newspapers during the last decade. The offset printing process relies on the assumption that an uniform film of ink of right thickness is transferred onto the printing areas. READ MORE

  2. 2. Where did the ink go? The effect of liquid absorption on ink distribution in flexography

    University dissertation from Karlstad : Karlstads universitet

    Author : Sofia Thorman; Karlstads universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexographic printing; print mottle; ink trapping; absorbency; absorption non-uniformity; water-interference mottle; Chemical Engineering; Kemiteknik;

    Abstract : The appearance of a print is affected by the individual ink layers. If the ink is unevenly distributed on the substrate it lowers the quality. This thesis puts focus on how the liquid absorbency of a coated substrate impacts on the ink distribution in flexographic printing. READ MORE

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

    University dissertation from Karlstad : Karlstad University

    Author : Johanna Johnson; Karlstads universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Chemical Engineering; Kemiteknik; Flexography; Print Quality; Liner; Board; Newsprint; Water-borne ink; Dynamic Pressure; Plate Properties; Wetting;

    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

  4. 4. Dimensional Stability of Paper Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

    University dissertation from Stockholm : KTH

    Author : Per A. Larsson; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. READ MORE

  5. 5. Hygro- and hydroexpansion of paper Influence of fibre-joint formation and fibre sorptivity

    University dissertation from Stockholm : KTH

    Author : Per A. Larsson; KTH.; [2010]
    Keywords : ;

    Abstract : Paper is a versatile, cheap and environment-friendly material. Nevertheless, there are several factors limiting its usefulness, and one of the major issues is that cellulosic and ligno-cellulosic fibres spontaneously sorb water. At the same time, the water uptake changes the dimensions of the paper. READ MORE
