The amount of colours any monitor displays is not necessarily determined by its brand or size. Monitor colours are determined by the bit depth which ranges from 1 bit depth (Bitmap) to 24-32 (true colour). The 24 bit depth represents about 16.7 million colours and this is the highest you can obtain from the very best of the cinema display ranges. The PowerBook like the Cinema display are both LCD monitors and they function in exactly in the same principle providing exactly the same amount of colours. They only differ in terms of screen resolution which has nothing to do with the quantum of colour. The higher screen resolution offered by the cinema display is only necessary in view of the size of the screen. In the context of the cinema display ranges, there is a direct relationship between the size of the monitor and screen resolution. The larger the screen, the higher the resolution it needs for images to appear the same size and in the same detail (M Freeman, 2003: Digital Photography). I will reserve my comments regarding CRT monitors when compared to LCDs for another occasion, but it will suffice to say that the rules about the quantity of colour display applies to both equally. > > In some areas of the spectrum, the capabilities of your 2100 will far exceed > the gamut of your PB monitor.

The colour calibrations kits that are marketed all over (by all means, it is a good idea to have one) but it is not inevitable in other to calibrated your PowerBook monitor. As I emphasised earlier, with the PowerBook and the OSX software in addition to Photoshop CS, any additional colour calibration kit is simply luxury. > > Most manufacturers produce generic profiles but each and every 2100 is different from another. I certainly disagree. Did Epson tell you that? The profiles provided by Epson works in "my" 2100 when setup correctly. While we are here, the issue of which colour profile to work with is entirely dependent on the environment which the image is destined. For an example, Alamy want their image output in RGB 1998 so you certainly have to work in that colour space which finds an equivalent in Europe Prepress Default setting in your Photoshop. It is perfectly legitimate to alter the colour settings if your work is localised as when printing to your own desktop printer such as the Epson 2100. I experimented by changing the RGB setting to LCD colour, and as I have said I obtained a perfect match. You have developed custom profiles for your printers and this is also OK. > ...I like to wear the very finest > tailor-made suits from Savile Row. > Incognito will be better, in my opinion! However, I will dread wearing a blue pin-stripe Servile Row jacket with a blue pin-stripe Incognito trouser, if you see what I mean.
