"Adobe RGB is a bigger colour space than sRGB + can produce more accurate colours."

This is a common misconception, as it really depends on what you consider accurate. Here are some facts:

* sRGB and AdobeRGB both have the same number of colors
* AdobeRGB describes some colors that you can not display on a monitor and is intended to better cover the gammut of CMYK printing
* sRGB describes a 'normalized' color set that can be displayed by monitors

Both AdobeRGB and sRGB can work to fulfill your workflow needs, but sRGB, to me, is more reliable on screen AND for my printing needs. In fact, the manufacturers of the laser-light printers I prefer (they use photographic digital process where photographic paper is exposed using lasers and then run through chemical process) generally suggest using sRGB for the best results.

AdobeRGB has unspoken pitfalls. If you fail to properly tag your AdobeRGB image, you will likely get washout in print (as your printer will likely assume sRGB, not AdobeRGB), but the same goes for uploading images where not all uploading applications or web browsers are savvy handlers of AdobeRGB.

I explore this and more in courses I teach on editing with photoshop and color management.

As far as printing...I don't bother with a home printer. I send everything to a local shop via FTP, and pick it up when I am out. The printer they use costs somewhere in the range of $60-$80,000, and I won't be buying one for home really soon. They remain responsible for calibration and supplies, AND mistakes. And my cost per print is less than it would be owning my own printer (when arguing that, don't forget the cost of the printer itself, upgrades, maintenance, and the time you put in learning to use it, calibrating, cleaning, and taking up space in your home/office).

I hope that helps!
