The Dorset-based printer was awarded the title as a result of UKAS-accredited laboratory tests on prints produced on the company's Xerox iGen3.
ADP can now offer artists Guild-branded, digital reproductions of original paintings to artists across the country.
Charles Anderson, director of Advantage Digital Print, said: "We have found a way to provide the art community with a quick and affordable print service while maintaining the superior quality required in this market."
Work submitted by the printer had to meet a raft of standards that covered light fastness, media pH and media weight.
To produce the artwork, the company captures digital images of each piece, which are then colour-corrected and matched to the original piece before being printed on the iGen3.
Anderson added: "Xerox's iGen3 met the strict requirements set by the Fine Art Trade Guild print standards and is clearly the right technology for us to deliver fine art reproduction."
