I have been using the HP Premium ID Satin paper with a Z3100-generated profile, and having a hard time defeating the blue color cast, in color prints as well as black & white. When softproofing from CS4, using adjustment layers with variations of Hue/Saturation and/or Color Balance, I have been only partially successful.

I had always rejected the Photo Filter adjustment layer as too simplistic, but one time, just for the helluvit I tried it. Lo and behold!--using the Warming Filter (85) between 8% and 12% seems to re-neutralize the color balance for color as well as B&W. I'm not sure if the variation is because of the nature of individual images or just my visual inaccuracy, but this method seems quite satisfactory as well as the least fussy I have found yet.

I have not tried this on other papers yet, but for the first time in almost 2 years I am able to correct my softproofed images to print correctly on the Z3100 using HPPremium Satin!

Are you printing directly from Photoshop CS4 using the standard Z3100 RGB printer driver?
Do you get a blue cast even if you convert an image to b&w in Photoshop and then print using a QTR b&w profile?
