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
- 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.
