Can't decide between K7 and Pro inks for my 7900

[Hardster]

So I have decided to convert my 7900 with clogged Black channel to piezography. I don’t understand how the optimiser is applied with the K7 inks. Is it a second pass after the initial print is made? How do I prevent the print being guillitined before this is done? How is this programmed into the software? I like the idea of the Pro inks having the optimiser applied at the same time but am a little wary of remapping the channels.
Thanks in advance. H

How to Re-Map a Piezography Curve

Here’s a quick article on remapping a Piezography curve. Remapping is used when one or more channels on a printer have died. Because Piezography does not normally require every available channel on your printer you can place a Piezo ink in a normally un-used channel and then remap the curves to use that channel instead of the bad channel. For example. If you have a 7900 that has a bad LC channel and you want to print with Pro ink, you would use the K4 Cool curves that do not require the Green c…
