Re: Low Dmax on Epson 2200 with K7 inks response

Milt,

I've been away from the PC for Thanksgiving.  Not sure if you have found a solution yet.  
John, is on the right track.  I am also using K7 on a 2200.  You need to make sure that the 
files are being sent to QTR as GrayGamma 2.2.  You can do a direct conversion to that 
working space, or you can use print preview, "Let Photoshop determine colors", and select 
GG2.2 for the profile.  I will add one caveat that when I was using the Cone curves printed 
from GG2.2, I occasionally had the same problem that you are experiencing on SOME 
images printed on HPR 308, and I can't figure out for the life of me what caused it.  I have 
since then purchased an i1, and am now using QTR create icc to profile the output, and I 
am now THRILLED with the output on Innova Photo Smooth Cotton.  

I got this idea from Walt and Steve - since they are using ABW to provide linearization, and 
QTR create ICC to profile the results.  It has worked well for me on the Innova products.

I can tell you that I have not been able to profile HPR very well yet.  When I use a 51 patch 
target, QTR create ICC tells me that the data is out of order, and in fact it is.  The 21 patch 
target does allow me to create a profile, and I have achieved satisfactory prints with this 
profile.  This whole thing is an issue that I need to address to Cone, but have not had time 
to figure out how to present it in a logical way.  Since I have quite successfully profiled 
both Innova Photo Smooth Cotton, and Soft Texture, I suspect there is something funny 
with HPR, or with the Cone curve for HPR.  I haven't bothered to figured it out yet, because 
I have been so pleased with the Innova papers.  

I noticed that someone posted to the piezo forum that it isn't 100% that's the problem, but 
75%-95% - I can relate to that problem, and I'm not sure of the solution.  I'd be happy to 
send you a copy of my HPR icc profile if you want to give it a try - contact me off list.

Someone also suggested that you might be printing on the wrong side of the paper - try 
the lip test.  Lick your lips (get 'em wet but not too wet) and then squeeze them on a piece 
of HPR.  The side that sticks to one of your lips is the coated side.  Make note of which 
side was up in the box, so you don't have to lick every sheet!  :) 

In summary, I have found the best results when using K7, QTR, the Cone Curves for k7/
QTR, AND QTR create ICC to profile each paper.

Good Luck.

Josh
