<p>There is described a method of rendering non-ink accepting a selected ink-accepting area of a printing member of a type comprising a support, a hydrophilic layer derived from a silicate liquid in which particulate material is dispersed and an image layer, the method comprising treating the area to be rendered non-ink accepting with a hydrophilising means, suitably selected from one or more of acids and/or alkalis and/or oxidising formulations or, alternatively, said area may be rendered non-ink accepting by covering it with a non-ink accepting formulation.</p> |
