Fairly early on in the digital photography & inkjet era I discovered QuadToneRIP, or QTR, as a better way of printing monochrome images using an Epson inkjet.  Since around 2007 I’ve been using QTR in conjunction with Jon Cone’s Piezography system to print monochrome.  Piezography uses six (K6) or seven (K7) shades of black / grey and no colour inks.  The Piezography and Printing section of the blog contains the following series of ten articles on using QTR and K6/K7/P2:
