Tom, Could you please just clarify part of your first paragraph below - "converting your image colour space using the ICC profile for your curve..."? I appreciate the help that you and others have given me, but to be honest - and without wishing to sound at all ungrateful - all this is starting to give me brain fade. So, to try to clarify at least something and establish a starting point for myself, put in simple terms: If I make a print using QTR and that my monitor accurately enough shows how that print will look, yet I don't happen to think that the blacks are 'right' - then should I simply forget using the curves that ship with QTR and make some of my own? Since we can agree that neutral curves don't use any black ink, does that mean that I need to accept that printing with a neutral curve set limits the blacks? Does it make sense to you for me to create a new curve set - call it whatever - and add the black ink and then go about linearising etc? Otherwise, I am starting to feel a bit bewildered by all these seemingly continually conflicting methods and workarounds. Is there anothere post, or some documentation on a website or within the software that I may have not yet read that will explain in clear steps how to go about the matte paper procedure you say you have described? -- Alan Ansell aansell@... ----- Original message ----- From: "Tom Moore" <rtmlists8888@...> To: QuadtoneRIP@yahoogroups.com Date: Fri, 20 Apr 2007 17:09:38 -0000 Subject: [QuadtoneRIP] Re: Soft Proofing QTR in Photoshop Alan I had described the procedure for matte papers, but the photo paper is analagous. It seems that, buried deep in your lengthy reply, you are doing what I would do when printing with QTR, i.e. converting your image colour space using the ICC profile for your curve (in your case the generic profile QTR-Gray-Photo) before saving the TIFF for printing. The process works for me. I do see a small change on the screen sometimes when I do the conversion. I think that's natural when you consider that ink/paper would not have the dynamic range of a monitor. However, you should be able to get as good blacks with QTR as you have with Paul's curves and the Epson driver. If you're not (with the same ink/paper/printer), then something is wrong. Possibly the QTR curve you are using is the culprit. On another note, although I haven't used UT2, I have used UT7, which is a similar inkset design. I don't think the K is used when printing on photo paper. I can see that's true (by looking at the qidf) for QTR. I am almost certain that it's true for Paul's curves as well.
