Are you interested in printing onto canvas or other porous materials? Do you need to print something that will last, and can withstand the sun and weather? If so, then you might be interested in solvent printing. Solvent printing is based on the use of high-grade solvent inks, which require special printing machines and equipment. It is very expensive compared to the simpler inkjet printing that most people use for home or office printing. It also requires media that is more high quality than general use copy paper.
