Apparatus and method for printing using a coating solid
View Patent ↗An apparatus for ink-jet printing including an ink-jet print head to jet ink, a coating solid, and a coating holder to support the coating solid, wherein the coating holder transfers a portion of the coating solid onto a medium to form a coating solid layer. The coating holder and coating solid may be combined in a removable cartridge. In addition, the medium may be an intermediate transfer medium, a media support medium, a transfer medium, or media, such as paper. A method for inkjet printing also includes applying a coating solid to a medium to form a layer of the coating solid, in a solid form, having predetermined thickness, and applying ink to the medium. The layer of coating solid may interact with the applied ink to destabilize colorant in the ink.
1. An ink-jet printer, comprising:
an ink-jet print head to jet ink;
a coating solid to interact with ink to destabilize colorant in the ink; said coating solid being a gel with a lamellar crystal stricture, and
a coating holder to support the coating solid,
wherein the coating holder transfers a portion of the coating solid onto a medium having a roughness of 0.05 microns to 1.5 microns Ra to form a coating solid layer.
2. The ink-jet printer of claim 1 , wherein the medium is an intermediate transfer drum or belt and the ink is jetted onto the intermediate transfer drum or belt.
3. A method of printing within a printer, comprising:
applying a coating solid to a medium having a roughness of 0.05 microns to 1.5 microns Ra to form a layer of the coating solid, in a solid form, having predetermined thickness; said coating solid being a gel with a lamellar crystal structure, and
applying ink toward the medium,
wherein the layer of coating solid interacts with the applied ink to destabilize colorant in the ink.
4. The method of claim 3 , wherein the medium is an intermediate transfer medium.
5. The method of claim 3 , wherein the coating solid and ink are both applied to the medium, which is an intermediate transfer medium, and another medium is made to come into contact with the intermediate transfer medium to transfer the coating solid and ink to the other medium.
