Abstract
Disclosed is a printing process which comprises (a) providing a recording sheet which comprises a substrate, at least one monomeric salt, an optional binder, an optional antistatic agent, an optional biocide, and an optional filler; (b) applying an aqueous recording liquid to the recording sheet in an imagewise pattern; and (c) thereafter exposing the substrate to microwave radiation, thereby drying the recording liquid on the recording sheet.
Claims20
A printing process which comprises the steps of (a) providing a recording sheet which comprises a paper substrate and at least one monomeric salt;
- (b) applying an aqueous recording liquid to the recording sheet in an imagewise pattern;
- and (c) thereafter exposing the substrate to microwave radiation, thereby drying the recording liquid on the recording sheet.
A printing process which comprises the steps of (a) incorporating into an ink jet printing apparatus a recording sheet which comprises a substrate and at least one monomeric salt, wherein the ink jet printing apparatus also contains an aqueous ink;
- (b) causing droplets of the ink to be ejected in an imagewise pattern onto the recording sheet, thereby generating images on the recording sheet;
- and (c) thereafter exposing the substrate to microwave radiation, thereby drying the recording liquid on the recording sheet, wherein the printing apparatus employs a thermal ink jet process wherein the ink in the nozzles is selectively heated in an imagewise pattern, thereby causing droplets of the ink to be ejected in imagewise pattern.
A printing process which comprises the steps of (a) providing a recording sheet which comprises a substrate and at least one monomeric salt;
- (b) applying an aqueous recording liquid to the recording sheet in an imagewise pattern;
- and (c) thereafter exposing the substrate to microwave radiation, thereby drying the recording liquid on the recording sheet, wherein the recording sheet also contains betaine.
