I would like to ask if anyone printing inkjets has noticed a dulling of sharpness and contrast in their inkjet prints with time. A friend of mine showed me two inkjet prints of an identical image. One was printed a day of so before, the other two one was printed two weeks before. The older image was noticably less sharp and contrasty. Colours were similar. Both images were printed on glossy paper. I have also noticed a similar effect with my own inkjet prints. Initially I'm very happy with the sharpness of the resulting print that comes out of the printer. A day or two later I'm still happy, but if I look at the the print a week or two later the print seems softer.
Digital prints I've had made at the lab on real photo paper from my 4x5 Velvia scans do not exhibit this problem, they still look sharp whenever I look at them. I'm fairly certain I'm not imagining this effect. Is it just me? or have others experienced this ?
