We were surprised to read over on the QuadTone RIP users list that a QTR user alerted Roy Harrington to the possibility that the Epson X890 and X900 printer control codes might actually be the same as the X880 control codes that are currently within existing QTR framework. Both printer families apparently use ESC/P2 ESC/P3 control codes. Apparently, this information not public in USA was published in Europe. You just never know when an inquisitive product user is going to tip you off to something that can benefit everyone else.We do not know exactly what this all means or where it is all going, other than that we can produce Piezography K7 curves for these printers now using the Windows platform. It is still impossible to work from Mac without an update in QTR. But, I am hoping that Roy Harrington will fully develop a new release of QTR that will address all of the ink channels in these printers.
