In a press release issued yesterday, Printroom.com and EZ Prints have announced a partnership to provide professional photographers with e-commerce "storefronts" for selling prints, with the added benefit that the prints are produced through an ICC color-managed workflow.
The storefronts are hosted by Printroom.com and print fulfillment is performed by EZ Prints, whose service is capable of reading embedded ICC profiles in uploaded images and making the appropriate color space conversions for the company's various printers. This would appear to make Printroom.com/EZ Prints one of the few online printing services to observe embedded profiles (a capability they've offered since at least mid-2003).
