Distinctness of Image (DOI) is receiving increasing attention as an important appearance attribute that correlates with the customer's perception of “photo-like” quality in digital photography. In this paper, a new measurement technique for DOI introduced recently is applied to the evaluation of inkjet photo papers. The principle of the technique is first reviewed; and the test results for about 40 commercial inkjet photo papers are then reported. The papers are mostly of the microporous, “instant-dry” type, with 60° gloss in the range of 30-90. The printers used are an Epson R800 and an HP 5500, both with pigmented inks. The DOI results are discussed in terms of correlation with perceptual (subjective) ranking, objective quality measures such as specular gloss, and physical properties such as surface roughness. The effect of printing on DOI is also investigated in terms of the printer type, color and tint level.
