Final answer:
A function of a prepress workflow solution includes optimizing digital files for printing through proofing and color management but does not include the physical printing of the materials.
Step-by-step explanation:
A prepress workflow solution is designed to optimize the process of preparing digital files for printing. Some of the common functions of a prepress workflow include proofing, color management, preflight checking, and layout adjustment. However, it is not a function of a prepress workflow solution to perform the physical printing of materials. Instead, prepress workflows prepare the files for the best possible output during the actual printing process which is performed by printing presses.
