  • Wet offset printing form
    Patent number: 7051652
    Abstract: A wet offset printing form has atop layer containing a photocatalytically and thermally modifiable material. The material can be brought photocatalytically into a hydrophilic state by irradiation with light and into a lipophilic state by heating. The hydrophilic state forms a surface that can be illustrated and the lipophilic state forms an illustrated surface. The top layer of the wet offset printing form may contain absorption centers for irradiation, especially for laser radiation in the NIR range, with which heating of the top layer in the pattern of an image is brought about.
    Type: Grant
    Filed: March 28, 2002
    Date of Patent: May 30, 2006
    Assignee: Maschinenfabrik WIFAG
