To calibrate a monitor properly, you need hardware such as a +Spyder, which can produce an ICC colour profile for the device. You can +find them on eBay. Some of these devices are said to work in Linux, +others are Mac and Windows only. Years ago they were pretty much all Mac +only, since that's what the graphics design profession all used. + +The cheaper LCD monitors have only 6-bit-per=channel colour in them, so +there are many colours that the computer can represent that the monitor +can't display. Unfortunately, there are also many colours they _can_ +display that can't be printed (and vice versa). The range of colours a +device can print or display is called its gamut. Monitors and printers +generally have overlapping gamuts, but not identical, and the cheaper +monitors tend to have much less of an overlap. + +To get anything like reasonable sRGB coverage (close to the 8-bit +default colour profile used by GIMP) you typically need to spend USD$600 +or more... look for an "IPS" display for example. But you'll still need +to do calibration if you're doing serius print work. + +If you don't want to spend the money, or don't have it, or would rather +buy shoes and socks :-), then search the Web (or check the CD that came +with the monitor and printer) for .ICC or .ICM files; in Gnome 2 you can +use [gnome]->system->preferences->color profiles to load them, and you +can also tell gimp (and I think cups) about them. + +If you have a scanner you can do the same with that, and then print +something and scan it and compare the files -- it's OK if they are a +little different, especially if you grabbed someone else's ICM files +rather than the ones for your individual device, because devices vary in +manufacturing and with age, and because the colour gamuts differ. + +In gimp, image->image properties can show if there's an embedded colour +profile in the image. If so, you can use exiftool on the command-line to +remove it and see if that helps with printing; see also +gimp'sview->display filters->colour management configuration, and +edit->preferences->colour management. + +Liam + + +-- +Liam Quin - XML Activity Lead, W3C, <A HREF="http://www.w3.org/People/Quin/">http://www.w3.org/People/Quin/</A> +Pictures from old books: <A HREF="http://fromoldbooks.org/">http://fromoldbooks.org/</A> + +</PRE> + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="005070.html">[Mageia-discuss] Gimp printing +</A></li> + + <LI> <B>Messages sorted by:</B> + <a href="date.html#5071">[ date ]</a> + <a href="thread.html#5071">[ thread ]</a> + <a href="subject.html#5071">[ subject ]</a> + <a href="author.html#5071">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-discuss">More information about the Mageia-discuss +mailing list</a><br> +</body></html> |
