Sypder2, the monitor calibration product, is excellent. My monitor never looked this good! Documentation is a bit terse, however. Additionally, you have to know how to do a few things such as (1) disable a program from starting when you boot up and (2) manually adjust your monitor for brightness, contrast, and color temperature and reset it to the factory defaults. Of these, the most important is probably knowing how to disable Adobe Gamma on startup (if enabled), and this is not explained adequately. Some patience and possibly a call to tech support may be required.
PrintFIX PLUS (the printer profiling tool) is less intuitive and more difficult to use. There is no printed documentation, and the Help files are a bit terse. You start by picking a printer/paper combination (any one will probably do, but pick a matte profile if you want to make matte prints). You probably won't find your printer/paper combination in the list, but it really does not matter. These profiles can be used as starting points for profiling of any color printer. You disable the ICM profiling included with your print driver (in the print dialog box for your printer), then make a test print. You compare your test print with an image of the print on your monitor and then make adjustments for brightness, saturation, contrast, color, and viewing conditions.
It's an iterative process to be sure, and some patience is required. The printer profile that I created was much more accurate than any of the ICM profiles provided by HP. It made a HUGE difference in print quality.
I use the ICM profiles from Spyder2 and PrintFIX PLUS in conjunction with Photoshop Elements 4.0 and do all of my critical color printing from within that application. (Note: the ICM profiles that you create with these products are accessible from within the Photoshop Elements Print dialog box. You don't have to install them.)
Additionally, I have not experienced any crashes or other instability issues when used with Windows XP as reported by one reviewer.
Conclusions/Recommendations:
Spyder2 is recommended for any intermediate or advanced amateur photographer who uses Photoshop Elements or equivalent. Novices might be better off with Spyder2 Express, which is considerably cheaper but less robust.
PrintFIX PLUS is recommended for anyone who has some experience making color prints requiring color correction and that has an older printer or even a newer one with inadequate ICM profiles to get satisfactory results. Patience is required.
