I would like to create an icc profile for my Epson 2400 using the QuadToneRIP 2.5 utility but I have a ColorVision PrintFix Pro Spectrometer rather than the Eye-One spectrometer. Can I create an icc profile with the ColorVision spectrometer and the GretagMacbeth MeasureTool program? If so, could someone please walk me through the steps I need to do. Thanks, Stan

Stan. Download version 2 of the PrintFix software from Colorvision. I haven't tried it myself, but v2 can now export measurements to QTR. Keith Cooper has added a review on his Northlight site if you want a run- through. http://www.northlight-images.co.uk/reviews/printfix_pro_v2.html Regards. graham --- In DigitalBlackandWhiteThePrint@yahoogroups.com, "stanraucher" <stanraucher@...> wrote:

Graham, Thanks for the link. It looks like I will have to read that article carefully. So far I've just been using the ABW mode with my Epson 2400 and getting good results, so I have two more questions: Will the results that I get using QTR and PrintFixPro 2 be noticeably better than what I can do with ABW? Is it possible to soft-proof prints using QTR? (I'm actually haven't done any soft-proofing in my current workflow, so I don't know how important that is to me).

Hello, I recently posted the following question on another group but did not get a response. This question may help with your question and maybe someone will be able to answer both of ours. Thanks, Gary W. I have an Epson 3800 and am using Print Fix Pro with Epson Velvet Fine Art paper. I did a test for Grayscale Linearization that I found on the Northlight Images website. I profiled the EVFA paper using the 729 patches plus the extended B&W. When I print it in B&W the center of the circle in the very dark areas has has defined tones and it is not smooth in tone. When I print it using the Advanced Blank & White Epson mode the the gray tones are very smooth. I can use the ABW on this paper but want to profile other papers. Is this an issue of the profiling and I should do it again or a weakness of the profiling process? How successful have other been using Print Fix Pro for B&W?

I'm sorry to have to confess that your problems may be the result of a weakness in my linearization targets, rather than anything else. There was quite a bit of helpful discussion about this when i first uploaded the targets to this group and i promised to re-do them, but with one thing and another i haven't got round to it. Your message has reminded me that i need to get this done, and i'll try to upload a revised version (both here and on NorthLight) within the next few days. Apologies if my delay has given you a headache. Regards. graham

Graham, The problem is with the circles at the 9 point there is a defined line that is present with my profile from Print Fix Pro but not with ABW. Does this sound like the same issue? Thanks, Gary W.

Try running media setting checks with other settings, and see if you can find one with better dark-end characteristics. Just because a setting works well with Epson's profiles or configurations doesn't mean it will necessarily be optimal for raw prints for custom profiling. C.

>I am not able to correctly read the greyscale target supplied >with QTR with the ColorVision spectro because of the targets small size. I made a new one that works well. See http://home1.gte.net/res09aij/21-Step_0-100_L16_Un-Tagged.jpg (This one has some markings relevant to matte paper with a 1.68 dmax.) I also put a little white mark on the outside of the PFP spectro at the reading 'eye' so that I could see how the unit was positioned on the dark patches. Paul www.PaulRoark.com

The part that you read will be the same with any method. Averaging four pixels of the same value gives the same result as cloning one of that value. C.
