You should also check with the print shop, if they have experience with colour managed work-flow and what are their expectations of colour encoding. You would know that once you ask for the preferred profile for images in RGB space or for a particular CMYK profile of their printer. If they do not tell you much useful information, you'd better look somewhere else to have your images printed... regards, Milan Knizek knizek (dot) confy (at) volny (dot) cz http://www.milan-knizek.net - About linux and photography (Czech language only) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Branko, There's a wealth of information to process there - thank you so much. I really would rather do this work on Linux or not at all and you've given me everything I can imagine needing to know.

Branko, that was extremely informative. Thank you. >Yeah, I thought you meant laser printers. Some people >confuse 4-color laser printers with real CMYK-capable >machines. Actually, I didn't know the difference. Thanks again. >You can get Huey at a very low price, and you can >use Argyll CMS with dispcalGUI to get the maximum out of that device >(software that comes with it is not very good, though).

I've just installed seperate+ and when I get familiar with it, I'll try this out.

Thanks folks. I didn't understand the CMYK seperator filter so I didn't use it. I'm pretty sure the printing company are using CMYK printers and apple computers - so I might ask them what color profile I should use. I'm designing on a cheap laptop so I guess the lack of calibration isn't helping. I looked at the color modes too but the only choice is sRGB, which I'm already using.

You could convert to CMYK using the separate+ plugin if that's what you want. http://cue.yellowmagic.info/softwares/separate-plus/index.html -- Praveen On 1 April 2010 21:01, TenLeftFingers wrote: > I've noticed (and since learned) that when an RGB graphic is printed on a > CMYK > printer, the output can be much darker - perhaps more saturated? > > Anyway, I'm wondering if anyone can recommend modification I should make to > my images before sending them to the printer.

So, you can get the most accurate results using a calibrated monitor, Gimp's color management in "Color manged display" mode, and sRGB profile for your image. You can get better results by calibrating your printer, though. -- Branko Vukelić Check out my blog: http://www.brankovukelic.com/ Check out my portfolio: http://www.flickr.com/photos/foxbunny/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I've noticed (and since learned) that when an RGB graphic is printed on a CMYK printer, the output can be much darker - perhaps more saturated? Anyway, I'm wondering if anyone can recommend modification I should make to my images before sending them to the printer. I've considered simply brightening the image, but I'm thinking that there might be a smarter adjustment to make. Thanks!
