摘要： PROBLEM TO BE SOLVED: To provide a technology for highly precise print quality management by improving the accuracy of estimating strike-through density in a print quality control device. SOLUTION: In the reference image generating section 10 of the print quality management device, an estimated strike-through information storage section 12 stores estimated strike-through information, which is information on the estimated effect of strike-through, created by a sampling functioning section 11 in advance. If strike-through density information which is not affected by the density on the surface of paper and information on a correction coefficient used for correcting strike-through density due to the density on the surface are stored as estimated strike-through information, a simulation functional section 13 determines the strike-through density by using the density of an image on the back of the paper when forming a reference image from the data of an image on the surface of the print paper, obtained from an upper system. Its reference value is corrected using a correction coefficient obtained at the density of an image formed on the surface of the paper. Thereby, the effect of strike-through from the back to the surface is estimated. COPYRIGHT: (C)2010,JPO&INPIT
