In QTR GUI there is a Media panel with two drop-down selections: SOURCE and TYPE. SOURCE selects a paper path if a printer has more than one; it is disabled otherwise. But what (if any?) effect does the TYPE setting have? Richard

Stephen, I know "media type" means "kind of paper." What I'm trying to find out is what -- if anything -- this setting actually does. The Epson driver changes its ink curves based on the media type setting. But that shouldn't be happening here, since I select the curves I want in the Curves selection box. What -- if anything -- changes in how the QuadTone RIP prints if I select, say, Matte Paper instead of Luster in the Media Type selector in QTR GUI, but don't change curves?

Try it and see. In the Epson driver, a lot more is changed than curves: ink type in particular (matte or photo), ink load, feed suction, etc. and the curves don't change at all unless you are using printer color management (same as source in Print w/Previewe) Scott --- In DigitalBlackandWhiteThePrint@yahoogroups.com, "Richard Wolfson" <rw@r...> wrote:

The Epson driver certainly changes ink loading (what I meant by "curves") as a function of media type no matter what color management scheme is in use. Of course, certain media settings are synonyms for certain others in some printers. Richard

The answer will have to come from Roy. I don't know what the print driver does with the media type information. -Stephen www.sbillard.org/Stephen

The more important question is "for what media were the curves you are using written for?". When someone sits down and develops a set of QTR curves they choose then which "media type". Ink levels, partition points and linearisation are all done with a particular media type set. In general, it is not a setting that one would change without redoing the curves.

The Media Type is a hold-over from gimp-print. It potentially could be used for "physical" properties of the paper such as thickness, platen gap, and feeding issues. From what I've observed I don't think this is ever used. I think all the current printers are pretty automatic for these things in their default mode. Unfortunately this area of the Epson documentation is vague to non-existent. I'm sure it doesn't effect the QTR profiles -- ink limits and such. At the moment I just leave it always on Matte Paper.

Do you leave it on matte if you are printing a semigloss, for isntance?? Diane At the moment I just leave it always on Matte Paper. Roy [Non-text portions of this message have been removed]

Yes, sorry I was thinking of profiles in PS. and on matte vs photo ink, I think the media type does it for all the epson wide formats but that except for the 4000 you have to also "help it" by changing the cartridge.

That's what I see in practice and what I see described in some Epson docs (vague though for the last). I think something similar is happening on the 9600 models. Changing to watercolor in the menu made banding much less with HM 310 gr. papers on my 10000. The firmware allows alignment changes in paper feeding etc related to the paper choices, but I find that quite complicated and it works alright now. I don't think this all was available on the 9000. There were paper thickness categories but not more. Ernst

Thanks Roy! I think that's the authoritative answer I was hoping for. Richard ________________________________
