| p.1 #8 · imac monitor calibration |
its quite easy to see the gamut of any Mac monitor in 3D vs editing and printer color spaces using the Colorsync utility. Here are plots from my 24" DuoCore iMac:
Select the profile you want in gray first. Then using the drop down menu under the triangle in the upper left corner select "hold for comparison" and then pick a second one. The images above are screen shots, but in the utility you can rotate the wireframes.
Seeing color spaces in 3D really makes it easy to understand how they relate to each other. The monitor is roughly the size of sRGB and much smaller than AdobeRGB. The gamut of my HP 8/C printer is much more saturated in some colors and much less saturated in others. Here's how the printer gamut fits into the AdobeRGB editing space...
Almost fits, but not quite, because AdobeRGB was defined back in 1998 for offset printing not today's inkjets...
SWOP (Standard for Web Offset Printing) is a near perfect fit:
sRGB also fits inside of AdobeRGB:
The fact 8/C inkjets, even cheap $120 ones, are larger than AdobeRGB is why the larger ProPhotoRGB space is better for editing files for ink jet printing, but only if editing in 16 bit mode.
