As it is known, electrochromic printing is a wet process which involves either of the following: a) Printing on regular (untreated) paper by applying an aqueous sensitizing solution (containing electrolyte and dye) at print time. b) Printing on pretreated paper (with electrolyte and dye) but reactivating the paper with steam or water at print time. c) Printing on pretreated paper (dye mixture alone) and reactivating the paper with aqueous electrolyte at print time.
