(how printer ink may appear)
Yes, they may appear slightly different. Keep in mind our high-quality commercial canvas printing process utilizes CMYK colors. Unlike commercial printers, household printers and monitors use RGB.
(See image above) We will reproduce color from your submitted photograph file as closely as possible but cannot exactly match color and density because of limitations in the printing process, monitor calibration, and image resolution requirements. You most likely won't notice this kind of color shift in a color photograph. It is more likely to happen if you pick a very rich, vibrant color for a background or some other element of your layout.
Sometimes photos are over-saturated or underexposed with colors. Also, since canvas is such a porous material it accepts colors and inks differently than flat photo paper.
