PURPOSE: To reproduce particularly a high density section in a good manner when printing is carried out by a back print film by the ink jet method. CONSTITUTION: When a high density section sensing circuit 31 judges that a feed amount data (x) obtained from a print data is judged to be larger than the value α determined based on a print image information by a threshold determining circuit 32, the feed amount x' of density improved ink is determined based on the feed amount data (x) by a density improved ink feed amount determining circuit 33. The density improved ink is jetted to the spots to which a dye ink of a back print film is jetted in compliance with the feed amount x' by a density improved ink head section 34. |
