I decided to order the sample pack after doing some prints with QTR on Ilford Smooth Pearl. Nice print with gradations, no gloss diferential but the bronzing on shadow areas is bad.
We'll see if I have better luck with FBAL.
No, but I have printed color on my 4000 and it worked very well.
Of course, with the Ultrachrome inks gloss differential is really quite noticable and I suspect that this will be especially the case with the QTR monochrome prints.
However I suspect that you will probably get about the best mono prints you will see from a 7600 on a gloss paper with this combination.
