Graeme, All I need to is to read a patch and make sure it prints out at that value. What would be the difference between doing this with a grey scale patch versus a color patch? Is the issue with making the profile versus just doing the reading? Would 'colprof' reject the readings? I know that the QTR set up by Roy Harrington can prepare monochrome profiles via this same approach. I was hoping that I could do the same thing with Argyll rather than purchasing another software package. thanks, Alan -----Original Message----- From: argyllcms-bounce@xxxxxxxxxxxxx [mailto:argyllcms-bounce@xxxxxxxxxxxxx] On Behalf Of Graeme Gill Sent: Tuesday, July 05, 2011 7:57 PM To: argyllcms@xxxxxxxxxxxxx Subject: [argyllcms] Re: FW: Profiling Epson ABW Print Driver Alan Goldhammer wrote: > darker black than the normal RGB driver and an almost linear response.

There's not a whole lot to doing so, but there's not been much demand to complete the fiddly details. Graeme Gill.
