Abstract
Abstract An ink jet printing method for effecting printing on a print medium such as a sheet of cloth by applying a jet of an ink to the print medium. The print medium is formed by preparing a sheet of cloth containing a cationic substance, preparing a backing sheet having a layer of an adhesive agent, and bonding the sheet of cloth to the adhesive surface of the backing sheet. After the jet of ink is applied to the print medium, the sheet of cloth is peeled off from the backing sheet and the freed sheet of cloth is rinsed with rinsing water containing a cation blocking agent, followed by drying.
