So finally i was able to sent you a message but be aware to read the segments in reverse order because of no more than 420 characters at once rule...
Sorry Admin if i broke in with dirty boots after minute of signing up. I needed this words, being screwed up regarding QTR.
Thank you, Dan.
The most strange is the fact that on Youtube find no tutorial videos about QTR, but instead on other disscutions people asking each other how to do and no step by step answers for a real case.
So i see an uncovered area that may be usefull for more printers ...
The main reason, to control the channels independently, since i start with grey inks mixed from Inktec Ultrachrome pigment PK, LK, LLK and filled the color and grey carts, alongside with MK for the black channel.
