摘要:
A printing process using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the printing process, the ink is subjected to a pH change to be provided with an adhesiveness to a desired depth, and the resultant adhesive ink is supplied to a printing plate having a pattern of ink receptibility to form thereon an ink pattern corresponding to the ink receptibility pattern. The ink pattern is then transferred to a transfer-receiving medium such as plain paper to form thereon a recorded image. In the above-mentioned printing process, a uniform thin ink layer can be supplied to the printing plate by chemically regulating the amount of the ink to be supplied.
