Definitions

  • S305 follows and it is determined whether the data is for a scan job (job formed by reading the original by the scanner 104) or PDL data by referring to an attribution flag attached to the print job received in S302.
  • the color/monochrome conversion method can be selected from the RGB conversion method, NTSC conversion method, and uniform RGB conversion method.
  • the input job is the scan job, the color/monochrome conversion is executed by the sRGB conversion method and another color/monochrome conversion method cannot be selected.
  • the color/monochrome conversion of the sRGB conversion method is executed in S308.
  • the monochrome conversion of the sRGB conversion method density of the pixel of the isolated point becomes thin and becomes difficult to be visualized.
  • the color/monochrome conversion method selected by the user from the plurality of color/monochrome conversion methods is applied. For example, if the RGB equivalence method was selected with reference to the color/monochrome conversion method in S306, a portion 1008 of the ellipse is reproduced at large density as illustrated in Fig. 10C.
  • Fig. 11 is a flowchart constructed by adding a generation copy discrimination of S1101 to the flowchart of Fig. 3 of the first embodiment. This flowchart differs from the flowchart of Fig. 3 with respect to a point that the generation copy discrimination of S1101 is added in place of S305 in Fig. 3.
  • Fig. 11 is the flowchart illustrating a flow for processes in the third embodiment.
  • a program for realizing the flowchart of Fig. 11 has been stored in the HDD 108. The stored program is read out into the RAM 110 and the CPU executes the program, so that the flowchart of Fig. 11 is executed.
