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

    Författare :Lars Bergman; Björn Kruse; Antanas Verikas; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datorteknik; multicolour printing; printing process; colour images; colour impression; CCD-camera; Datorteknik; Computer engineering; Datorteknik; Multicolour printing; Printing process; Colour images; Colour impression;

    Sammanfattning : 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. LÄS MER

  2. 2. The importance of paper properties in digital colour printing

    Sammanfattning : The fast development of digital printing technology has created new possibilities to produce printed material. With office and desktop devices, printing has become a routine in offices as well as at home. LÄS MER

  3. 3. Situation Awareness in Colour Printing and Beyond

    Författare :Jens Lundström; Antanas Verikas; Juan A. Botía Blaya; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Data mining; Colour printing; Smart homes;

    Sammanfattning : Machine learning methods are increasingly being used to solve real-world problems in the society. Often, the complexity of the methods are well hidden for users. However, integrating machine learning methods in real-world applications is not a straightforward process and requires knowledge both about the methods and domain knowledge of the problem. LÄS MER

  4. 4. Appearance of textured and pigmented polymeric surfaces

    Författare :Sofie Ignell; Chalmers University of Technology; []
    Nyckelord :surface texture; polymer; gloss; colour; perception; appearance;

    Sammanfattning : The appearance is of increasing importance in the production of premium products since it is strongly connected to the quality impression. The surface appearance of any object may be described in terms of colour and surface characteristics such as gloss and texture. LÄS MER

  5. 5. Dot Gain in Colour Halftones

    Författare :Stefan Gustavson; Jonathan Amey; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The incomparably most common way of reproducing images in print is by halftoning, whereby varying levels of grey or colour are simulated by small dots with maximum colour density but with a varying local fractional area coverage, printed on a white substrate. Whenever such a reproduction is used, a ubiquitous effect called dot gain comes into play and makes the actual image appear darker than what would have been expected from a perfect reproduction.
