Hi David,

The iMac 21.5 has a monitor similar to my old (not very old) imac 24. To get a 
match to that 2400 printer. You'll probably end up with the brightness turned 
all the way down, particularly if you're working in dim light. There are 
expensive calibration devices that can help you determine that. But you can 
also go with a bargain calibration device, like the ColorVision Spyder2 Express 
that I use. You do need to calibrate at least for color accuracy. The Spyder2 
does a good job on that. I think it sells for about $70. I see B&H now has a 
Spyder3 Express. I assume that's somewhat of an upgrade. It sells for about 
$100.

Once your monitor is accurate in terms of color balance, saturation and  white 
point (Spyder2 can handle all that quite well), you'll just have to deal with 
brightness. A bit of trial and error works best here. Once you get a print that 
you consider perfect, simply tweak the monitor brightness adjustment to match. 
As I said, I think you'll find that you have to turn it all the way down, or 
almost all the way down. You can spend more money and try to dial the monitor 
in  more precisely before you ever make a print, but I think you'll find some 
manual tweaking will still be needed. The printer and monitor are two different 
animals, and coupled with the operator's subjective judgement, that means that 
it's all somewhat imprecise science. But a decent calibration tool will ensure 
that you're close on color balance and saturation. That's almost impossible to 
achieve manually.
