The one in the original post is simply a monitor profiler. All it can do is create a monitor profile so your colors look correct on screen. It is useless for your printer. You need an Eye One Pro - if using an actual RIP your RIP may have profile creation built in. FlexiSign Pro for example does - it has built in support for an Eye One colorimeter and can walk you through the entire profiling process from setting ink limits, scanning in the color patches, setting GCR, etc.
Pre-made profiles from equipment, media, etc companies will never be as good as a custom one made for your specific machine in it's actual enviorment, ever. Every print head has it's own ever so slight variations, and the enviorment the machine is in also makes a big difference. Their profiles are made in their enviorment at their average room temperature and humidity, on their printer. When I first got our eye one several years ago - I made our first custom profile and the difference was dramatic. Not only was the color more accurate but I actually got a wider color gamut available than what the Flexi provided profiles would allow.
You also need to create a profile for each material AND each resolution for each material you plan to print for the best results. Granted - most do not go to quite this extent. Like many I have a couple of different profiles made on 3M 180 vinyl at different resolutions. These work "acceptably" for the most part on just about any gloss adhesive vinyl. Then a couple of profiles for banner stocks, a couple of display films, a couple for heat transfer materials, etc.
Also if you go to aftermarket inks like Triangle which have a wider gamut than stock inks you also need custom profiles. In the end - not only has it allowed us to have more consistent output and better color accuracy, it has also saved an unmeasureable amount of money over the years from not wasting so much material trying to match colors or wasted prints because they look bad.
It is still not going to give my solvent Mimaki the color range of a 8 to 12 color water based ink printer but it's pretty darn good and acceptable quality for many artists I have done prints for over the years.
