  3. 2. Automated CtP Calibration for Offset Printing : Dot gain compensation, register variation and trapping evaluation

    Författare :Shahram Hauck; Sasan Gooran; Björn Kruse; Peter Nussbaum; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Although offset printing has been and still is the most common printing technology for color print productions, its print productions are subject to variations due to environmental and process parameters. Therefore, it is very important to frequently control the print production quality criteria in order to make the process predictable, reproducible and stable. LÄS MER

  4. 3. Compression uniformity measurements on coated anduncoated paper surfaces

    Författare :Isabel Endres; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Paper is exposed to compressive stresses at several occasions in its production process and in subsequent printing operations. In the press section of a paper machine, the fibre web is mechanically dewatered by compression. LÄS MER

  5. 4. Printability and Ink-Coating Interactions in Inkjet Printing

    Författare :Erik Svanholm; Göran Ström; Gunnar Engström; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER

  7. 5. 2D and 3D Halftoning for Appearance Reproduction

    Författare :Fereshteh Abedini; Sasan Gooran; Daniel Nyström; Jan Morovic; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The appearance of an object is determined by its chromatic and geometric qualities in its surrounding environment using four optical parameters: color, gloss, translucency, and surface texture. Reconstructing the appearance of objects is of great importance in many applications, including creative industries, packaging, fine-art reproduction, medical simulation, and prosthesis-making.
