Claims
- 1. A method for making a printing plate precursor by applying a coating solution onto a substrate by means of a valve-jet print head, thereby obtaining a heat- or light-sensitive image-recording layer.
- 2. A method according to claim 1 wherein pressurized gas is used for driving the coating solution out of the valve-jet print head.
- 3. A method according to claim 1 wherein the valve-jet print head is mounted on a shuttle that is movable over the substrate.
- 4. A method according to claim 1 wherein the image-recording layer is applied onto the substrate by means of a plurality of valve-jet print heads.
- 5. A direct-to-plate lithographic printing method comprising the steps of:
making a printing plate precursor by a method as defined in any of claims 1 to 4; image-wise exposing the image-recording layer to heat or light and optionally processing the image-recording layer, thereby obtaining a printing master; applying ink and/or fountain solution to the printing master; removing ink accepting areas from the lithographic substrate by supplying a cleaning liquid thereto.
- 6. A method according to claim 5 wherein all the steps are carried out while the lithographic substrate is mounted in a printing press.
- 7. A method according to claim 6 wherein the substrate is a plate cylinder of a printing press or a plate or a sleeve mounted on a plate cylinder of a printing press.
- 8. A method according to any of claims 5 wherein the image-recording layer is removable with the ink and/or fountain or is rendered removable with the ink and/or fountain upon exposure to heat or light.
- 9. A method according to claim 8 wherein the ink is single-fluid ink.
- 10.A method according to claim 1 wherein the image-recording layer comprises hydrophobic thermoplastic polymer particles and a radiation-to-heat converting compound.
