Curves for IGFS on 3880
2014-11-05 by jeff.grant@...
I've hunted in the files but can't find anything for IGFS and a 3880. IGFS is mentioned in a number of posts. Is there somewhere else that I should be looking to find them?
Cheers,

I'll take that as a 'no'.

I don't have a 3880 so no direct experience with that exact issue, but I looked in the 3880 profile install folder and do not see a IGFS curve set to install. QTR does not have curve sets available for every paper, not being Roy, or others making curves for distribution, my impression is that they try to cover papers most used, or most representative of a segment of the paper market.
Without specific provided curves to install, the general approach to my knowledge is to use curves for a paper that behaves very similarly. In your case, you have 3 PK paper curve sets there to try i ncluding an Ilford smooth, one or more will be very very close if not identical. These coatings linearize very similarly. To fine tune an unsupported paper, you simply relinearize a curve set that is working well, or easier- make a qtr profile with an exisitng paper curve set to use when printing. That's what I've done for others who regularly use QTR.

Thanks Tyler. That's just like Colorburst was. I was just hoping someone had one that I could use as a starting point. I guess that I should be linearising for my printer anyway.
It would appear that I have upset Jeff Schewe on LuLa for not wanting to use ABW.

then you are in good company...
Hope your QTR work goes well.

Eposn ABW — there are a lot of words that start with A, but "advanced" is not one I would use. As for Shewe and lulu: I tend to judge the quality of people's answers based on the quality of their work, and, if you are asking about black and white, it can be slim pickins there.
I can understand the drive to get printing asap, but don't get too upset that people don't respond here as fast as places like lulu. Sometimes posts I have made wont show up here for 6-12 hours (and sometimes not at all).
I'd rather make prints than constantly messing with QTR profiles too, but learning the process can teach you a lot about how ink is laid onto paper and can lead to sending more refined image data to the printer.
The best way to use QTR is to build your own profiles and not rely on others people have already created. The supplied profiles might not actually be all that good, and you won't know why your print isn't meeting your expectations and blame the software or paper. There is a lot that can vary from paper to paper, and minor tweaks to some settings can often lead to huge jumps in print quality. Learning what the densities look like at each of the crv creation steps can influence how you build the profile for different papers.
My best advice is to get a used photospectrometer if you don't have one already. Then learn to set your ink limits, cross-over points and linearize your curves for each paper. Starting from scratch isn't very hard for K3 printers, or editing the supplied starter profiles like "UCpk-raw-neut.txt". The Diallo QTR workflow is a good place to start—it doesn't go into all the details, but it is enough to get you off the ground.

Many thanks, Richard. I always build colour profiles for the papers that I use. Now I understand that it is just the same with QTR. Having used ColorBurst RIP in the past, I've done linearisation etc so it's a matter of coming to grips with a variation of what I already know. It just took me a while to realise that.
I have both an i1Pro, i1Pro2 and a converted io so hardware isn't an issue.
Once I get it sorted, I will be very happy to go quiet and print.
Cheers,
Jeff

On the 3800, I have obtained good results using the Silver Rag curves for IGFS and a custom profile made with a Spyder Print, which I recommend as an affordable spectro.

Due to illness, I've lacked the time and energy to go all the way and make custom curves as well, but I intend to do so for IGFS and other papers, when circumstances allow me to spend the time doing so.
I got Amadou Diallo's book out of the library and it was worth reading. It's cheap second hand on Amazon (except for the excessive postage on second hand books there, which often means there is little price saving over new copies in my experience). I must buy a copy.
Good luck,
Richard

Thanks Richard. I've just ordered a copy of the book. I need all the help that I can get at the moment. I will build a profile for IGFS and use it as a learning exercise. I really like it as a colour paper and have heard good reports on it as a B&W paper.
