Abstract:
A printing method for block copy film, comprising the steps of: when performing monochrome printing based on printing data by selectively causing exothermic elements lined up and formed on a recording head to generate heat while a carriage is being moved along a platen for transferring black ink mounted on the carriage onto transparent resin film, and thereafter by repeatedly conveying the transparent resin film in a sub-scanning direction of the carriage,setting a predetermined mount of conveyance of the transparent resin film to 1/N, N is an integer of 2 or more of a printing width, which is a line-up width of the exothermic elements, at the commencement of printing, printing at a width obtained by substituting M=1 in M/N, M is an integer of 1 or more, Mconcerning print lines to follow, repeatedly printing at a predetermined printing width after the transparent resin film is conveyed in the predetermined amount of conveyance, and at the completion of printing, printing at a printing width obtained by setting M=N in the printing width from the lower end of the predetermined printing width and thereafter, repeatedly printing at a printing width obtained by deducting 1 from the M of the immediately preceding printing width from the lower end until M=1 is reached.
