Going back a long way here. I used Imageprint briefly back in the early days of the Epson 3800 and instead ended up using B&W profiles made by one Eric Chan (who was promptly hired / hijacked by Adobe) !
Can't comment on how they make their profiles, but
How many printers do you use ?
How many papers do you need to profile?
I found no practicable difference with Hahnemule profiles (I only used two paper types and one printer) and for more discerning requirements used Chau Digital (London UK) for printing.
Fine art, photographic, archival, giclée, digital inkjet printers in London. Papers such as Hahnemuehle (Hahnemühle), DaVinci, Canson, Awagami. We print with experience, care, and attention to detail; we strive to get the best out of your images to produce stunning prints time and time again.

Now, I use EU based pro photo labs who do their own profiling.and print on a variety of papers and surfaces. A lot has changed in the intervening 15 odd years and I see that IP have tried to moderate their pricing structure but sadly not their piracy protection. We're 2024 do we still need to rely on a dongle - do you really need this ?
Colorbyte's lost dongle policy is repaying software - does this only concern me?

This thread dates back to 2018 but it's still relevant today. Replacement dongles (if the still work are $40 bucks plus shipping and taxes , if they're too old (os pre 64-bit) it's $150 plus shipping and taxes. If you or the courier service loses the package - it's full cost of a new IP licence. (

Imageprint is more than an ICC stage in the print process and IIRC, the other package highly praised was QImage Ultimate
I can see a use of IP for those living in the USA, but possibly less so for those of us in the EU.
Good luck!
Note: the cheapo IP-RED does NOT include their library of ICC profiles - for those you've got to pay an extra $300 plus for the BLACK version.
