Abstract: When a job does not exactly match the purpose of a printing profile but would benefit from some of the characteristics of a different printing profile, dynamically making the tradeoffs between the printing profiles is desirable. For example, a high-ink, large gamut profile might not be needed for a particular job, but an ink-saving profile would be excessively grainy. An intermediate profile would be recommended. Alternatively, the ink-saving profile can be adequate for everything except the skin tones in the print. Presented here are systems and methods to create a blended representation that could adopt the high-ink rules for a portion of the image, but ink-saving rules elsewhere. For example, the high-ink rules can be applied to the skin colors, but ink-saving rules can be applied in other parts of the image.
