What makes a print photographic quality? The answer is clearly more complicated than resolution or color reproduction. Even factors like paper weight are part of photographic quality. Another factor is gloss, which varies from the paper base to the image areas. Images with variable gloss do not appear to be photographic quality. Try this test with a digital print or photo book: Hold the print or book under relatively direct over lighting at various angles. If parts of the image appear glossy at certain angles but not at others then the print is not photographic quality.
Gloss is dependent on the paper, ink, and any lamination. Selecting the best materials will minimize gloss differences. At Creative Memories, we now have a gloss meter available to measure these differences. I expect that these measurements will lead to future improvements in photographic quality. After all, quality is important when it comes to preserving memories.
