One downside to this approach is that the piezo inks cost a little over twice as much. I also don’t know whether you’ll need GO over all prints that use opaque photo black. If you’ve got the kit to create these then that makes it easier. Of course you may need custom profiles for both matte and gloss. I’ve no idea, and it’s not something that I’ve seen mentioned, but it might be worth a try. So I wonder if you could use WN shade 1 opaque photo black for colour work. There’s a slight dmax loss on matte, but it’s not something that most people notice. The answer to this problem came in the form of WN shade 1 opaque photo black, which can be used on matte and gloss. However once we were able to print piezo on glossy, then the same problem returned - wasting ink in the PK / MK switch. It wasn’t that expensive (initially) as I bought an inexpensive 1400 and used K6 inks. It was why I bought a second printer, to do B&W on matte using piezo. I’ve been making a lot of posts here lately, but I feel compelled to reply to this one.
