Abstract
A method and system for enabling a patterned liquid, can involve creating a heat image on an imaging blanket by selectively heating the imaging blanket with a digitally controlled energy source, and subjecting the heat image to a selective deposition of a fountain solution material to enable vapor condensation on unheated areas and vapor rejection from heated areas to generate a fountain material image.
Claims17
A method for enabling a patterned liquid, comprising:
- creating a heat image on an imaging blanket by selectively laser heating the imaging blanket with a digitally controlled energy source;
- subjecting the heat image to a selective deposition of a fountain solution material from a vapor phase to enable vapor condensation on unheated areas and vapor rejection from heated areas to generate a fountain material image;
- wherein the digitally controlled energy source comprises a light source that heats a surface region of the imaging blanket;
- and
- wherein the light source comprises at least one of:
- a vertical cavity surface emitting (VCSEL) array, a light emitting diode (LED) array, a laser light source that emits a pixilated light beam as a pixelated line laser beam, or a modulated laser line source.

A system for enabling a patterned liquid, comprising:
- an imaging blanket;
- and
- a digitally controlled energy source, wherein a heat image is created on the imaging blanket by selectively laser heating the imaging blanket with the digitally controlled energy source, and wherein the heat image is subject to a selective deposition of a fountain solution material from a vapor phase to enable vapor condensation on unheated areas and vapor rejection from heated areas to generate a fountain material image;
- wherein the digitally controlled energy source comprises a light source comprising at least one of:
- a vertical cavity surface emitting (VCSEL) array, a light emitting diode (LED) array, and a laser light source that emits a pixilated light beam as a pixelated line laser beam.
2 more elements
A system for enabling a patterned liquid, comprising:
- at least one processor and a memory, the memory storing instructions to cause the at least one processor to perform:
- creating a heat image on an imaging blanket by selectively laser heating the imaging blanket with a digitally controlled energy source;
- and
- subjecting the heat image to a selective deposition of a fountain solution material from a vapor phase to enable vapor condensation on unheated areas and vapor rejection from heated areas to generate a fountain material image;
- wherein the digitally controlled energy source comprises a light source comprising at least one of:
- a vertical cavity surface emitting (VCSEL) array, a light emitting diode (LED) array, and a modulated laser line source.
