As mentioned above your printers gamut is measurable with special software. I use X-Rite's i1Profiler to do that, in combination with an iSisXL in my lab. After measuring the target and building an ICC profile for your printer if your on a Mac simply double click the ICC profile and select the gamut view. If you want to compare gamuts just do the same to ...

As a matter of fact gamma is not necessary these days, especially when working in high bit representations of the image. However that means a complete software rewrite in far too many cases - or the transition is far from seamless (say, familiar curves change the shape completely, as Mr. Blankertz just mentioned).

Here's my first draft of an answer- I'll get into more detail as time allows, but I want to give the OP some sort of answers. Comments are more than welcome. The stuff about CRTs does not indeed apply anymore. But there is a very good practical reason to continue to use gamma encoded images. Using gamma encoding make edits like curves look "normal" because ...

Every monitor is different, you can't expect any two monitors to display colors the same way unless they are calibrated - and by calibrated I mean you used an hardware device that reads the color from the screen and created a color profile, you can't calibrate a monitor using the monitor's controls. Note that manufacturers tend to mis-calibrate the monitors ...

Firstly, you can't really say "less blue" - monitors and printed ink function under completely different viewing conditions. Monitors are backlit. Printers and their inks also differ wildly in quality. But in some sense, you are right. CMYK just a mixing model and top quality photo printers don't use it anymore anyways.

Exact blue is exact blue in all color spaces. If you have a specific color in one color space and convert it to a different color space, it's still exactly the same color (provided that the color is actually possible to represent in the new color space). The color code will be different, but it still represents the same color. If you create a very bright ...

Suppose one wishes to design something with two colors: the most saturated bluish-purple a printer can produce, and another shade of bluish-purple that is 5% less saturated. If one is using CMYK, one may express those colors as (100%/100%/0%/0%) and (95%/95%/0%/0%) and be assured of both getting the most saturated bluish purple the printer can produce, and ...

Ease of print color mixing. When you are using ink based printing, any application of ink darkens a white page, thus making it difficult to get a true sRGB color space in prints without many inks. If you use a dark blue ink, you can't easily produce light shades of blue. By using lighter shades and a black filler, you can mix the amount of darkness you ...

CMYK is based off of offset printing capabilities where you are using only specific shades of Cyan, Magenta, Yellow and Black ink being laid down from separate printing plates to print full color. It isn't mechanically capable of reproducing very saturated colors. But ... most photo inkjets don't expect you to send generic CMYK files to them. They have ...

CMYK CMYK is a subtractive colour model rather than an additive as in the case of sRGB. The subtractive colour models are used in printing since they allow dyes, ink or paint pigments to absorb certain wavelengths from an otherwise white surface. The dyes, ink and paint pigments can be a very limited discrete set that are mixed to get a wide range of ...

The covered range of colors (called gamut) is different between color spaces because these ranges are then discretized, "digitized", represented on a fixed amount of bits, and then reproduced on a monitor, in print, etc. One wants to store as much color information as possible in a certain amount of bytes. Now, if you have an equipment which can only emit ...

As Raymond Chen would put it, developers hate to pay taxes. Colour management is a very big tax on Windows. Developers are expected to ask Windows what colour profile to use and then do all the RGB conversions themselves. (And let's not even get started on the added challenges of multiple monitors!) Most developers don't know any better so they just draw ...
