  1. 1. On the evaluation of print mottle

    Författare :Carl-Magnus Fahlcrantz; Jan-Olof Eklundh; Jon Hardeberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mottle; Print quality; Texture; Image analysis; Perception; Computer science; Datalogi;

    Sammanfattning : Print Mottle is perhaps one of the most disturbing factors influencing overall Print Quality. Mottle has traditionally been evaluated by estimating the reflectance variation in the print. LÄS MER

  3. 2. Interfacial Adhesion Failure : Impact on print-coating surface defects

    Författare :Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER

  7. 5. Variations Related to Print Mottle in Starch-Containing Paper Coatings

    Författare :Micael Ragnarsson; Lars Järnström; Gunnar Engström; Martti Toivakka; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pigment coating; porosity variations; coating structure; coat weight variations; starch; dextrin; CMC; latex; print mottle; calendering; pilot coating; offset printing; Chemical Engineering; Kemiteknik;

    Sammanfattning : Starch in paper coatings is known to increase the risk of print mottle in lithographic offset printing. The objective of this study was to increase the understanding of this behaviour. LÄS MER
