  4. 22. Using Multicoloured Halftone Screens for Offset Print Quality Monitoring

    Author : Lars Bergman; Björn Kruse; Antanas Verikas; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datorteknik; multicolour printing; printing process; colour images; colour impression; CCD-camera; Datorteknik; Computer engineering; Datorteknik;

    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

  5. 23. Mathematical Modelling of Light Scattering in Paper and Print

    Author : Per Edström; Mårten Gulliksson; Inge Söderkvist; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; radiative transfer; solution method; numerical stability; speed; light scattering; light absorption; Kubelka-Munk; errors; reflectance calculations; MATHEMATICS; MATEMATIK;

    Abstract : A problem formulation and a solution method are outlined for the radiative transfer problem in vertically inhomogeneous scattering and absorbing media, using discrete ordinate model geometry. The treatment spans from the physical problem via a continuous formulation, a discretization and a numerical analysis, to an implementation with performance evaluation and application to real-world problems.

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

    Author : Sofia Thorman; Li Yang; Magnus Lestelius; Martti Toivakka; Karlstads universitet; []
    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
