We have characterized the effect of low and high humidity on dye-based and pigmented inkjet images stored in the dark. Prints in albums were evaluated unprotected as well as protected with polyproplyene sleeves or page protectors. In this work, we have examined the effect of humidity on gloss, dot-gain, sharpness, mottle, and color. Overall, humidity did not have as large an effect on image degredation as initially expected. The primary effect of high humidity was reduced image sharpness due to migration of one color into an adjacent area or into an unimaged area. Migration was greater with RC papers than with cast-coated papers. Pigmented systems showed essentially no migration. Mounting sleeves or page protectors reduced migration in systems where migration was observed. However, we recommend a proper storage environment as the best way to preserve inkjet images.
