Method of making an optically transparent inkjet printing medium
First Claim
1. A method of making an inkjet printing medium, comprising steps of:
- (a) selecting a microembossing pattern for forming a microembossed surface topography on the inkjet printing medium; and
(b) molding a polymeric material against a molding surface of a mold having the selected microembossing pattern thereon to form the inkjet printing medium, wherein the medium is a polymeric sheet having an optically transparent microembossed surface topography comprising square cavities as one major surface thereof, the microembossed polymeric sheet is nonporous and the cavities each have a volume of from about 1100pL to about 5000pL and the calculated percent non-planar area of the surface topography is 10 percent or less.

Abstract
A receptor medium with a sheet having an optically transmissive microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire'"'"' effects but also provides sufficient optical transmissivity to be useful as overhead transparency media, backlit signage, and the like. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire'"'"' effects. Methods of making and using the inkjet receptor medium are also disclosed.
