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

Amadou,
Thanks for the information. I will contact Ergosoft about their RIP. I was hoping to use a cheaper gateway but perhaps I won’t be able to. Roy mentioned I might be able to use the 9600 driver. Then he said I should contact you.
Thanks again and I will contact Ergosoft…again, if you have any ideas about this project, please pass them on.

Paul,
If QTR does not support the 10600, you’ll have to use a different inkset than K6, unless the current version of StudioPrint still supports 3rd party inks on that printer. Contact ErgoSoft to find out.

Amadou,
I have been referred to you by John Dean who said you might be able to advise me in this project I am doing. I am taking an Epson 10600 and converting it to use Cone K6 inks. I am using John’s method for refilling the carts as there are no refillable ones on the market that I know about.
I am going to use the Quadtone RIP but Roy has told me that there are no ink controls built for this machine. I hope you can sort of point me in the right direction as far as making this work.
I have been printing a lot with Imageprint and a 7880 and Epson inks. This 10600 printer was given to me for this project. Any help will be most gratefully accepted.
