Publication number: 20030235776Abstract: A lithographic printing precursor for lithographic offset printing comprises a layer of imageable medium on a hydrophilic base. The imageable medium comprises hydrophobic polymer particles in an aqueous medium, a substance for converting light into heat, and a coalescence inhibitor. The coalescence inhibitor can comprise an inorganic salt, an organic base, an organic acid and a metal complex. The lithographic printing precursor may be used to make lithographic printing surfaces that obtain long run lengths on lower quality paper and in the presence of press-room chemicals. The lithographic printing precursor can be imaged and developed on-press and the imageable medium can also be sprayed onto a hydrophilic surface to create a printing surface that may be processed wholly on-press. It can also be processed in the more conventional fully off-press fashion.Type: ApplicationFiled: June 24, 2002Publication date: December 25, 2003Inventors: Jonathan W. Goodin, John Emans, Keith Christall, Yisong Yu, Katja Rademacher

Publication number: 20030207210Abstract: The invention provides a method for making a lithographic printing surface using media with coalescence inhibitor. The lithographic printing surface is made on a hydrophilic surface using a radiation sensitive medium that comprises hydrophobic polymer particles in an aqueous medium, a substance for converting light into heat, and a coalescence inhibitor. The lithographic printing surface made by the method of this invention may be used for printing long run lengths on lower quality paper and in the presence of press-room chemicals. The method allows for on-press imaging and development of the lithographic printing surface. The radiation sensitive medium can also be sprayed onto a hydrophilic surface to create a lithographic printing surface that may be processed wholly on-press. It can also be processed in the more conventional fully off-press fashion.Type: ApplicationFiled: June 24, 2002Publication date: November 6, 2003Inventors: Jonathan W.

Publication number: 20030180658Abstract: A lithographic printing precursor for lithographic offset printing comprises, a layer of imageable medium on a hydrophilic base. The imageable medium comprises hydrophobic polymer particles in an aqueous medium, a substance for converting light into heat, and a non-crosslinkable aqueous-soluble composition. The lithographic printing precursor may be used to make lithographic printing surfaces that obtain long run lengths on lower quality paper and in the presence of press-room chemicals. The lithographic printing precursor can be imaged and developed on-press and the imageable medium can also be sprayed onto a hydrophilic surface to create a printing surface that may be processed wholly on-press. It can also be processed in the more conventional fully off-press fashion. The hydrophilic surface can be a printing plate substrate or the printing cylinder of a printing press or a sleeve around the printing cylinder of a printing press. The cylinder can be conventional or seamless.Type: ApplicationFiled: January 22, 2003Publication date: September 25, 2003Inventors: Jonathan W. Goodin, John Emans, Keith Christall, Yisong Yu, Katja Rademacher
