Abstract
A method for the preparation of a lithographic printing plate comprises forming an oleophilic image on the surface of a hydrophilic support by depositing, preferably by ink-jetting, the image on the surface using an aqueous dispersion of an oligomer having in the molecule both hydrophilic and hydrophobic groups. The number of repeating units in the oligomer may be from 2 to 10 and the number of hydrophilic groups in the oligomer may also be from 2 to 10. Preferably the molecular weight of the oligomer is from about 500 to about 5000.
