It is very simple to use the profiles supplied, and they're generally  
quite good. Here's how.

Assuming you are using Photoshop CS2 on Mac OS X (CS' and Windows  
nomenclature is a little different but you should be able to  
translate without too much difficulty), are working with a calibrated  
monitor, and an Epson paper for which a profile is supplied:

- Caveat: a point of confusion for many is that the monitor  
calibration profile is NOT what you want to set Photoshop to use for  
the color space. You tell the operating system what monitor  
calibration profile you want to use, independent of Photoshop, and  
you tell it the one that your calibration procedure generated.

- If you're using a color-managed workflow, be sure to set up the  
Color Preferences. I use the "North American Pre-press" preset  
preferences mostly. This sets "Adobe RGB (1998)" as the working  
colorspace, a good choice as it provides a broad gamut for editing.  
(ProPhoto colorspace is even larger gamut but I find it's not  
entirely necessary for my work.)

- When you open an image for editing, if it does not have a profile,  
Photoshop will ask you whether or not to assign the default working  
colorspace; tell it to assign the working colorspace. If it has a  
profile that isn't the working colorspace, it will ask you whether to  
use the embedded colorspace, whether to convert it to the working  
colorspace, or whether to NOT color manage it; i usually tell it to  
convert to the working colorspace. For easiest future editing, I  
always save my PSD files with the working colorspace embedded.

Ok, so you do all the editing you want to do and the image looks like  
you want it to appear on your print. ... btw, I usually do all the  
sizing required for my intended output in the image editing and do  
NOT use the Print with Preview facilities to scale output. More  
control that way.

- Select "File->Print with Preview...". In the dialog that appears:

1) Use the Page Setup button to select the specific printer and paper  
size, orientation parameters. Click OK.
2) Check to be sure that the image sizing and positioning is correct.
3) In the color management controls, use the option that tells  
Photoshop to manage the color space translations, use 'Perceptual' or  
'Relative Colormetric' intent, and pick the specific profile for the  
Epson R1800 and the paper you want to use.
4) click the Print button.

At this point, Photoshop transfers control to the print driver so  
you're presented with the Print dialog ...

- pick the option for Advanced Color, set the resolution for 'best  
photo', and pick the paper type
- in the Color Management controls, turn color management OFF  
(Photoshop is going to do the controls, not the print driver).
- Click the print button.

That's it. What comes out on paper should be a darn good match to  
what you saw on the screen.
