PROBLEM TO BE SOLVED: To enable stable and successful gradation duplication in an image formation device. SOLUTION: There are set a head control means 2 for controlling an ink delivery amount on the basis of nuance intelligence per unit pixel of a subject copy datagram, an inkjet head 4 which ejects ink in accordance with a driving waveform of the head control means 2 and performs image scan, a pattern generator 12 for generating a test pattern datagram by a predetermined starting timing, and an acceptor 5 to which ink drops ejected from the inkjet head 4 are adhered. The inkjet head 4 performs image scan on the acceptor 5 according to the test pattern datagram. COPYRIGHT: (C)2004,JPO |
