Abstract: In a multi-valued printer that uses discontinuous index patterns, if a tone correction table is generated using sampled density patches, a table which is different from a table to be obtained and has no inflection point is obtained, and the print density characteristics after tone correction suffer discontinuity. To solve this problem, an output gamma table used to output measurement patches is set to linearly correct the printer print characteristics. Patches are output and their densities are measured. A reverse table of a “signal value—density” table is generated, and is smoothed using a recursive curve. The smoothed reverse table is finely adjusted to generate an intermediate output gamma table. The generated table undergoes index component correction, thus generating a tone correction table.

Abstract: The present invention provides an image-forming device that can record an image onto a rewritable image recording medium. Prior to recording a predetermined image, the medium is set and a test image for measuring the density is recorded thereon. When the density is determined to be within an allowable range, the predetermined image is recorded under certain image recording conditions and then discharged to a discharging tray. However, should the density be outside the allowable range, the conditions are changed and another test image is recorded to the medium. If after repeated density measurements the density is not within an allowable range, the device determines that the medium is defective and discharges it to an error tray.

Abstract: A printer prints a black mark BM having a left mark edge BMa and a right mark edge BMb on a paper P. An encoder offset SH_L_EDG for the left mark edge BMa is set based on the difference between the carriage position (encoder value PR_ENC_L) that is detected when the print head 10 prints the left mark edge BMa and the carriage position (encoder value SEN_ENC_L) that is detected when the media sensor 68 detects the left mark edge BMa. Similarly, an encoder offset SH_R_EDG for the right mark edge BMb is set based on the difference between the carriage position (encoder value PR_ENC_R) that is detected when the print head 10 prints the right mark edge BMb and the carriage position (encoder value SEN_ENC_R) that is detected when the media sensor 68 detects the right mark edge BMb. In this way, the printer can suppress the effects of mounting error and can prevent a decline in accuracy when detecting edges of the paper P.

Abstract: A medium-edge setting device detects edges of a paper (S110) and acquires data for left and right edge candidate positions (S120). The medium-edge setting device determines whether the difference between left and right center-edge distances is less than or equal to a predetermined value (S150). If so (S150: YES), the right edge position is set to the right edge candidate position and the left edge position is set to the left edge candidate position (S160). If not (S150: NO), the paper is conveyed a predetermined amount (S190) and the paper edge detection is repeated. If the repetitions of the paper-edge detecting process exceed a predetermined number (S180: NO), then the larger of the left and right center-edge distances is set as the distance from the center of the paper to each edge position, and the left and right edge positions are set according to this distance (S200, S210, S220).
