Thank you all, the more I read the more confused I get! It seems that if I want cibachrome lookalike prints, as well as good quality luster/matts, on top of great B&W's then I really need two different printers (one K3, one with gloss optimiser) or a large can of spray for the colour/B&W K3 (anyone know of the equivelent in the UK? they won't ship) to solve the gloss diffrential unless I want to mess with some of the rather complicated options shown here...
I'm trying to go for an inkjet solution for both a studio's output and fine art printing, two sides of my business, it is rather complicated trying to find a machine that will print both cibachrome like colour and B&W, as well as a good (and fast)matt 6X4/12X8/18X12". I really liked the look of the Kodak papers, I'm used to the base and it would be an excellent continuity for my machine prints, however the pro paper is only in A4 and bigger. The ilford premier luster which would be another option widely supported by icc profiles and with a chemical like base, is unavailable in the UK.
Questions Questions, I have so many more than damn answers as far as inkjet is concerned!
