I’m installing Piezography inks after having Piezo Flush in my carts. I can’t seem to clear the Flush completely from my LC and Y channel, even after printing the Flush tifs through the QUAD Rip set in Calibration mode. I did this following the directions here: [How To Flush Individual Channel using QTR Calibration Mode] ( How To Flush Individual Channel using QTR Calibration Mode).
When installing the new inks I did 3 power cleans. After the 2nd and 3d I printed a photo and that is when I noticed pink toning. It did not improve AT ALL between the 2nd and 3 power clean so i went to this Forum to see if I could find a solution. (See above.)
I have a 3800, a Windows PC, and have remapped so that the QUAD Rip is not using the M and C channels. Specifically C was remapped to Y, and M was remapped to LLK. (I confirmed by looking at the Curve Graphs that indeed these channels are not printing when I choose my remapped curves.)
To use a .tif with the Windows version of the QUAD Rip files they have to be in grey scale (2.2) and saved with LZW compression. At least I know this works and that having the .tif in RGB will not work. I converted the individual channel flush.tifs in Photoshop to grey scale, saved with LZW compression. The K, LLK, LM, Lk individual images all printed as nice solid colors. The LC and Y images print as speckled pink and grey images. I have printed 8 copies of the LC image, and there has been no sign of improvement, not even slightly better.
I tried printing the LC from Photoshop (Photoshop manages colors) and the resulting image is a nice smooth grey.
I have a good nozzle check for all the remaining channels, and the nozzle check is printing in grey, not pink. (except in the M and C channels that I will not be using, and where I have Piezo Flush installed.)
Any suggestions for a next step?
