QTR-Quadtone RIP

Mike,

Thanks for your concern - but please disclose your method. Our profiling is a service rather than a business model. There are many people who simply like to do it on their own. You have some process that anyone can port to a spread sheet. Sounds great!

I find a lot of people who are wanting to make negative curves (for example) are looking for a from-the-ground-up process to follow. They want to know how to start from scratch and use the QTR tools to build a set of 6 or 7 curves.

Unfortunately my profiler can not make curves which are editable in QTR. 

Regards,

Jon
