OK guys, if you are going to have a serious go at this, I can offer the following from my prior usage:
a) buy, beg or borrow a spectrophotometer of some sort. It is only the device that matters as you won't be using its supplied software or charts. b) install and run Argyle and use that to print an Argyle test chart. Don't bother with the test chart or (probably windows) software that comes with your device. You are going to be using Argyle profiling software and Argyle format test charts, and it will do a much more comprehensive job than any entry/mid level commercial software. It will drive the ColorMunki well beyond its normal capabilities (probably) but is complex to understand. c) Print the Argyle generated test chart image using Gutenprint with whatever paper/ink/resolution combination you want the profile for. You MUST choose the 'Uncorrected' mode within Gutenprint for printing the test image. d) Now use the Argyle tools to drive the ColorMunki and measure the printed test image. This will generate your .icc profile. e) Now try printing a real image using gutenprint in uncorrected mode and with your new shiny profile selected. I must confess I hit a brick wall and couldn't get step (d) working properly. Graeme Gill (author of Argyle) was good enough to provide a patch which helped somewhat but we concluded that the firmware in my, otherwise excellent, spectrophotometer needed upgrading and with a borrowed device I couldn't do that. Good luck, Rob. -----Original Message----- From: Pascal Obry [mailto:[email protected]] Sent: 03 April 2013 17:06 To: Pascal de Bruijn Cc: Darktable-users Subject: Re: [Darktable-users] Screen profile and image histogram...

Printing using gutenprint for the charts? Does that mean that we can print without gutenprint? ... I may be confused :) I have installed the gutenprint debian package, so I do print with gutenprint right? Do I have an option to not use gutenprint? > I haven't been able to invest as much time into this as I'd wanted, > but if you're patient I _might_ be able to give some more sensible > tips in a month or so (I hope). Great! Let's work in parallel. I'll send a set of charts to some Web service in France to get profiles. I'll report my finding. I'm all with you to create a simple and understandable procedure for printing on GNU/Linux. I did not thought it was so difficult to get right!
