Abstract: Example embodiments relate to dynamic sharing of ICC profiles. A computing device may receive data representing a paper type, a customer precision requirement, and supporting parameters and perform a search of a paper catalog using the data for an existing ICC profile that satisfies the customer precision requirement.
