PageMaker, PhotoShop, and Corel Draw (among others, I'm sure) all come with color calibration tools. Look it up in Help or check the manuals to find the path that gets you there.

In all cases, you will be clicking some sort of vernier control up or down until something matches something else, to your eye, under your lighting conditions, using your monitor.

Beyond that, your publishing program or your print driver should enable you to select a color profile for the output device. (Oh, I'm sorry. Did you say you were using Word?)

All this is goodness and you should do it. However, you should not expect a huge benefit from it.

There are three basic reasons:

1. Different software packages (even from the same company) employ different color models. Converting colors between models and between platforms works sometimes and doesn't work sometimes. These problems can be quite vexing and require lots of detective work or trial-and-error manual correction. YMMV.

2. The boundaries of the overall color RGB space for phosphorescent radiated light (from your monitor) are quite different from those for the overall CMYK color space of light reflected from a printed surface. So at the very best you will only get a fair approximation of the final printed result when you look at your monitor, no matter how you calibrate it.

3. Perceived hues change dramatically under different lighting conditions. You might presume that all of your fine color work will be read by other people sitting under bright fluorescent light in cubes like yours. But your presumption might prove incorrect. Take some of your color work home and read it under a 100W incandescent lamp in your living room. Take it outside on a sunny day and read it there. Or read it on a bus, train, or plane under various weather and daylight conditions. Find a store lit with "warm white" fluorescents (try a butcher shop or an upscale clothing store). You'll soon see that calibrating your monitor is the least of your worries.
