The QuadToneRIP product has multiple pieces of code. The low level drivers for the Epson printers are based on Gimp-Print Open Source Project. This Gimp-Print code is licensed under the GNU General Public License. The rest of code for the QuadToneRIP product including Quad Tone Profiling, ICC profiling, installers and user interface are all proprietary work. Any usage of any piece of the QuadToneRIP product is considered usage of QuadToneRIP. In other words whether you are just printing, just using the ICC profiler or just using any of the profiles supplied you will be using some of the proprietary software.
All of the proprietary pieces of the QuadToneRIP product i.e. other than the Gimp-Print code are bundled together and licensed as a Shareware product. You are free to download and try the product. It is a fully operational product, there are no disabled parts or dongles. If it meets your needs and you want to use any pieces for your regular workflow, please pay a shareware fee of fifty dollars $50. At the present time there is no registration but this is subject to change. This fee can be applied per user so one user can use as may printers as he/she wants, or the fee can be applied per printer so one printer can be used by many users. The fee will also entitle you to any bug-fix updates. Profiles distributed here are included and others are free to swap and distribute profiles among other QuadToneRIP customers without restriction.
