I am using a brand of paper called InkPress with the luster finish. This paper is heavy on the OB and I specifically see see more of a tint under artificial light or light that has a very erratic spectral response. I am guessing this is the metamerism of the ink paper combination since I don't see the same intensity of the colour cast (but it is still there) under daylight. However, I am showing these prints under artificial light and would like to minimize this shift in colour. Do you think a profile that takes into account the ambient light would solve my problem if metamerism is the issue? Would switching papers that are more neutral to begin with be a good idea or are the OB taken into account when the profile is created and therefore this factor is eliminated.
Many thanks to all who are joining in on the conversation,
Cliff
Print the grayramp on another paper like Epson's using its appropriate profile and print settings and view under the same artificial light and daylight to check for green there. This will definitely point to a print driver problem or a print head cleaning issue which you might give a try as well.
As for having the profiling software correct for OB's you'll have to refer to Andrew's expertise on this. I've never made a custom printer profile or even had concerns with OB and their affect on mixing with the ink and paper color cast. I've always stuck with Epson printer paper, inks and canned profiles on a Photo EX, 1270 and now the NX400. I haven't printed in quite some time as well, but I do know what various lights do to the appearance of inkjet paper color casts but never changing color of inks.
With prints made with Epson inks and paper the only color shift under various lights is the color cast provided by the light itself with the 5000K GE Sunshine giving a slight reddish yellow tint to B&W, 50 watt Solux 4700K giving spot on neutrals, 100 watt Ottlight HD CFL slight bluegreen cast and the 100 watt Alzo Digital CFL a slightly blue cast.
