John, I’ve attached a zip file will a collection of flush images.
There’s an ink separation page which is just the standard one, but minus the column that fires GO/GCO, and with the columns re-ordered and relabelled for the R1900 / R2000 / P400. There’s text at the top that says R1900, but it works for other models as well.
There’s a 7 channel flush image that is just the standard 8 channel one with the same modifications. Again you need to ignore the SEL1 labelling on the Y channel and the NU labelling on the K channel, as this was for P2 inks.
There’s also a set of single channel flush images partly renamed for the three hi-gloss printers. For example, the file “QTR-LC flush - Re 3.tif” is the file that usually comes labelled LC , but which is for the Red channel on the hi-gloss printers, which is shade 3 on K6/K7/P2 inksets. You could amend these file names for Pro inks.
The purge image I posted a while ago was intended to provide maximum agitation, by moving the print head backwards and forwards a lot at 2880 super, but not consume too much ink. It wasn’t ideally suited for flushing and nozzle checking. I’m still working out how best to prevent and cure sedimentation by using that particular purge pattern. I.e. how many do I need to print and in what format. It takes time, as I need to wait until I see some drift in my linearity plots, which is usually about four weeks of little printing, and then try to agitate the inks.
If you look at the ink separation page, and look at the RGB values for each square on each column, the blue value is always 255, the red value signals which channel to fire, and the green value signals how much of the channel to fire, with 0 being 100% and 255 being 0%. But you these files should be sufficient, you shouldn’t need to dive into the RGB numbers, which are a code that QTR uses in calibration mode.
