I've successfully made printer profiles using the Spyder systems for quite a while now, but this week I've been frustrated while trying to do a profile for a matte paper, using the Epson 2880 printer. The initial white point comes out 95, which seems okay, but the black point comes out at 19 - way too high - and (of course) the resulting measurement file just can't be used to create a good profile. The soft proofed images look like I'm viewing them through fogged or frosted glass.

Can someone point out to me what is going wrong here, and how to correct it?

I should note that the "canned" Epson profile for this paper and printer is almost what it should be - color balance is spot on, but the profile needs slightly more contrast and perhaps a touch more saturation. I mention this because I think it shows that the printer itself is working as it should.
