ABSTRACT:
The invention relates to a method of preparing a printing plate includes ink-jet printing an oleophilic image on a surface of a support by applying to the support an aqueous solution or aqueous colloidal dispersion of a polymer having water-solubilising groups wherein the water-solubilising groups interact with the surface of the support thereby binding the polymer to the support and rendering the polymer insoluble, wherein the aqueous solution or aqueous colloidal dispersion of polymer comprises pigment particles dispersed therein.The invention further relates to a composition suitable for the preparation of a printing plate by inkjet printing including an aqueous solution or aqueous colloidal dispersion of a polymer having water-solubilising groups characterised in that said aqueous solution or aqueous colloidal dispersion further includes pigment particles dispersed therein.
