Supported Format of Document Data in Color Sample Matching

Color Sample Matching supports document data that fulfills the following conditions simultaneously:
  • Data in a format that is supported on the printer used to output "Original Data"
  • CMYK (Data containing special colors, RGB, grayscale, or DeviceN is not supported)
  • A PDF file of any of the following versions:
    • PDF1.3 (Acrobat 4.x) to PDF1.6 (Acrobat 7.x)
    • PDF1.7 Adobe Extension Level 3 (Acrobat 9.x)
    • PDF1.7 Adobe Extension Level 8 (Acrobat X)
    • PDF/X-1a
    • PDF/X-3
    • PDF/X-4
  • A PDF file with embedded fonts

Color matching might fail on the following images even if the above conditions are fulfilled:

  • An image that is entirely filled in a solid color and comprises no gradation or edge.Image filled in a solid color
  • An image comprising a design of line symmetry or rotation symmetry.Image comprising a design of line symmetry or rotation symmetry
  • When the same image is imposed repeatedly
  • Page comprises a lot of characters and line drawings
  • Page comprises an extreme color scheme, such as mainly containing colors of a specific color family
  • Page is covered entirely by a fine pattern
  • When the screen size is small
  • When using a color chart for color sample matching, the area outside the color patches that comprises the color chart is also subject to the effect of color matching.
  • Color matching may fail in the following cases even when you are using original data that can be used for color sample matching.
    • The color gamut of the printer to print the original data is too small.
    • The number of inks used in the original data and that of the printer used for printing differ, for example, when the color sample is printed using a printer with 4-color ink and the original data is printed on a printer with 7-color ink.
    • When the color of the paper in the color sample differs from the color of the paper loaded in the printer that prints the document data.
