Abstract:
1. A method of printing on a sandpaper surface, comprising: printing, with an inkjet plotter printer onto a sandpaper surface, a plurality of differently-colored aqueous ink compositions, each of the compositions having different polymer components whereby the ink compositions when printed onto a sandpaper surface using an inkjet printer are applied without bleeding between adjacent differently-colored aqueous ink compositions, said ink compositions including: 60% to 80% by weight of one or more polymer components selected from the group consisting of: polysaccharide and its derivatives; polyvinyl alcohol and its derivatives whose average molecular weight is around 10,000 to 200,000 daltons; polysucrose and its derivatives whose average molecular weight is around 40,000 to 400,000 daltons; and epoxy glycerol and propoxylated glycerol and their derivatives whose average molecular weight is 500 to 10,000 daltons; 2% to 10% by weight of a solvent dye or a pigment; 1% to 5% by weight percent of ethanol; 0.1% to 1.0% by weight percent of surfactants.
