Hi,
I finally found a way to use ColorPort and redifine + import the mesure file into it. See article above :

Thanks.

Hi Vincent,
Unfortunately I don’t have an answer for you. I have kept one of my older machines running OS 10.6 precisely so I still have access to the PM5 demo.IF you haven’t already, I would suggest asking in the QTR yahoo forum at http://tech.groups.yahoo.com/group/QuadtoneRIP.

Hello,
I want to create custom QTR curves following your level 3 tutorial but I have got a problem with ProfileMaker 5 because this software is no longer supported and the last version cannot be installed on a Mac with OSX Lion. So the solution is to use ColoPort that is apparently the succesor of PM5, but with this software, the file QTR-21×4-random.txt used on step 8 doesn’t work. The import methode for custom test charts seems to use another type of file.
Please, can you help me to find a solution ?
Thanks a lot.

Like the previous poster above, I’ve been using Eric Chan’s custom ABW profiles, but would like to experiment with QTR. Since I’m a Windows user, I’m finding there’s not a lot available regarding workflows and/or tutorials to learn the very basics. I am wonder if you could provide some additional info.
Thank you in advanced.

do the trick you did, but use sRGB instead of ProPhoto.
Things keep changing with each OS update and PS version, sRGB just worked for me when AdobeRGB didn’t after an OS change.

I recently started using an Epson 3880 and was wanting to build profiles for Epson Luster… really more as an exercise to familiarize myself with the process. I’m trying to follow the Mac oriented process outlined in the tutorial, but am running into a stumbling block printing the inkseparation8.tif file.

With 10.6.5 & CS 5, it’s simply not possible to print with no color management. I’ve tried a work around suggested on the Luminous Landscape: assigning a color space and printing with the exact same color space (I used ProPhoto RGB), and I’ve also tried a recently released Adobe utility that is supposed to bypass the API calls that seem to make printing with no color management impossible.

In both cases the resulting printed sheet looks nothing at all like what is printed in the tutorial. When printing via CS 5, the background is white, but most of the ink positions print nothing, and those that do (the first 2) show significant pooling of ink (to the point that it runs down the page). When printing with the Adobe utility, the results are very different – the background is magenta and most ink positions print something – but not the color expected and (again) with significant pooling.

Not sure what I’m missing here… any suggestions on how to print the inkseparation8.tif file correctly under 10.6.5?

I posted a few more details on the QTR user group as well.

thanks!

Trying posting on the QTR user group. THe more specifics and details you put in your question, the better the response you will get.

Hi, I just tried Quadtone Rip with my Epson 7600 and the prints are coming out way too light. I’m on Windows system, printing from TIFF files. Any thoughts?

Yes, you can use a densitometer but you’ll have to enter everything manually and you won’t get the benefit of averaged measurements, unless you do that by hand also.

Hi Amadou,

I’m a long time IJC/OPM user, but I’m getting the feeling they aren’t going to be supporting future Epson printers (and I’d like to print directly from apps like InDesign). Is it reasonably easy to linearize an existing QTR profile with a densitometer? Or do I need to get a spectrophotometer?

Thanks!

Jon
