Hi I have purchased a bottle of MIS UTFS-4-Y for use in the yellow slot of my 2100. Am I right in thinking that the existing EEM LC-in-Y curve is the best starting point for integrating this ink in to a 4-ink warm tone curve? What adjustments do I need to make to that curve so that this ink takes over from the LC ink in the best place? Thanks for any guidance Howard

Where did you find that curve? I dont see it anywhere. Best regards, John Moody

The EEM LC-in-Y curve is called UT7-2200-EEM-LC-in-Y-Carbon-6.acv and can be found on Paul Roark's page here: http://home1.gte.net/res09aij/UT7-2200-curves.html I couldn't get a satisfactory result by tweaking that curve & am now using Paul's 7k curves as a starting point but it's difficult without a densitometer. If anyone can help or has a matte paper curve designed for this combination I would be most grateful. regards Howard John Moody wrote:

I don't have Photoshop curves posted for the option of having UT-FS-Y in the yellow spot, but in general, I have the Blue curve (controlling the yellow ink spot -- FS-Y) carry the image entirely until about 229 on the horizontal axis, where I start the other inks (Red and Green curves). As an example, for Kirkland, a neutral curves set I use has the following points from 0% (255) to 25% (191): (255, 254), (251, 187), (247, 168), (242, 147), (229, 99), (216, 88), (204, 83), and (192, 82). For glossy Kirkland, I taper it off to (127, 146), (25, 0). For a matte paper the blue curve has to be full on at (0, 0) to help turn on the black ink. So, for a matte paper it'd be either raised and then lowered again or go about level, perhaps at a bit higher point so that the other inks were not limited too much. The Red and Green curves, as noted, start at 229, and are raised about 5 at 191 and about 15 at 127 relative to the starting curves that did not use FS-Y. I don't have a good comparison here, because I used the Ilford curves for Kirkland, which were not right on to start with. Print a 21-step with the current, starting curves and just eyeball the 50% and 25% patch densities to see how much the Red and Green curves need to be raised to offset the addition of the FS-Y. Hope this helps. Paul www.PaulRoark.com

Thanks Paul, that was helpful. I also found & read Dirk Hobman's article which also clarified what you said. In the end I started with a standard warm carbon curve, brought in the blue curve along the lines you suggested & then raised the red curve from the 165 mark ending at 229 to compensate for the extra light ink. There's alway the danger of losing separation between patches & the tweaking required made me appreciate the time & effort you have spent developing these curves. Howard Paul Roark wrote:

Thanks. I was thinking QTR curves, that explains it. Best regards, John Moody
