Methods for ink-based digital printing using imaging member surface conditioning fluid
View Patent ↗An ink-based digital printing method includes applying conditioning fluid to an imaging member surface wherein the fluid is absorbed by imaging member surface, which includes VITON. Dampening fluid is subsequently applied to the imaging member surface for development by a laser imaging system to form a latent image. Ink is applied to the developed latent image on the imaging member surface to form an ink image that is transferred to paper to form a print that is free of tiger stripe image quality defects.
1. A method for ink-based digital printing system, comprising:
applying a conditioning fluid to an imaging member surface whereby the imaging member surface absorbs the conditioning fluid, the conditioning fluid comprising a hydrofluoroether liquid, the imaging member surface comprising a fluoropolymer elastomer;
applying a uniform layer of dampening fluid to the imaging member surface, the surface being impregnated with the conditioning fluid; and
inking the imaging member surface after applying the conditioning fluid.
2. The method claim 1 , the imaging member surface comprising hydrofluoroelastomers, and hybrids and blends of silicone and hydrofluoroelastomers.
3. The method of claim 1 , comprising:
developing the uniform layer of dampening fluid to form a latent image by exposing the layer to laser radiation from a laser imaging system.
4. The method of claim 1 , comprising:
transferring the ink image to a printable substrate.
5. The method of claim 4 , the printable substrate comprising paper.
6. The method claim 1 , further comprising applying the uniform layer of dampening fluid to the imaging member surface after the conditioning fluid applied to the imaging member surface is absorbed by the imaging member surface.
7. A method for ink-based digital printing system, comprising:
applying a conditioning fluid to an imaging member surface whereby the imaging member surface absorbs the conditioning fluid, the conditioning fluid comprising a hydrofluoroether liquid: and
applying a uniform layer of dampening fluid to the imagining member surface, the surface being impregnated with the conditioning fluid; and
inking the imaging member surface after applying the conditioning fluid.
8. The method of claim 7 , the imaging member surface comprising a fluoropolymer elastomer.
9. The method claim 7 , the imaging member surface comprising hydrofluoroelastomers, and hybrids and blends of silicone and hydrofluoroelastomers.
10. The method of claim 7 , comprising:
developing the uniform layer of dampening fluid to form a latent image by exposing the layer to laser radiation from a laser imaging system.
11. The method of claim 7 , comprising:
transferring the ink image to a printable substrate.
12. The method of claim 11 , the printable substrate comprising paper.
13. The method of claim 7 , the imaging member surface comprising a synthetic rubber.
14. The method claim 7 , further comprising applying the uniform layer of dampening fluid to the imaging member surface after the conditioning fluid applied to the imaging member surface is absorbed by the imaging member surface.
