Qu 1: In this this post Dana C said that I could use K3 vivid inks in an R2400, so long as I made my own profiles. I assume that I could also use the K3 Vivid inks (less the LLK) in a 2100/2200 on the same basis? There's no technical reason why not?
Qu 2: Is the only difference between the K3 and K3 Vivid inksets the VM & VLM inks? I.e. all the others PK, MK, LL, LLK, C, LC, Y are the same between the two inksets?
[I'm asking because I'm trying to get some more life out of my 2100 & R2400, while I desperately search for an R2880 and contemplate an R3000 before the cashback ends. I need to order more ink soon and it may as well be K3 Vivid rather than K3, if the answers to both these questions is yes.]
