Profiling black and white ink sets
« on: December 19, 2007, 01:55:21 am »

I need to build a profile for a printer using a Lyson B&W inkset and printing via Photoshop.
I've got Profile maker Pro 5 and an iOne Pro available, but what target and reference file should I be using and where would I get them from ?

Thanks for any help

I think the cheapest and most direct approach would be to use Roy Harrington's QuadTone RIP, which includes a utility for making black & white profiles with targets you can measure with your set-up. Haven't done it myself, but I have read about it.

This is one approach I'd considered.
Has anyone else tried this with any success ?
Does it deliver absolutely standard ICC profiles anything can use ?

Thanks

No, in the past I have checked density numbers on greystep wedges and as it was designed and checked by Roy on Photoshop output it behaved correctly there with Perceptual rendering + BPC etc. That's one point to start from, you could do a P2P conversion to the QTR B&W printer profile and use that file without CM on in the application you print from if that isn't Photoshop. Photoshop's softproof works as well. You can use the greyscale version and the RGB version of QTR's profiles.

PWP, CorelDraw Photopaint 9, were not working properly with the profiles then but that could have changed meanwhile. PWP behaved very odd, both with the LCMS and the M$ color engine, however the ICC profile versions that it handles have been extended but I do not have that upgrade. Qimage could work but use the RGB QTR version profiles and BPC off. I find it too unreliable yet but have to do more testing. I use Qimage with CM off and drop greyscale files on it that have been converted in Photoshop.

There's a QTR list and subjects like this are discussed there too.
