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.
An 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

Note:

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.
