Quality won't even get close to a low end aqueous machine.
I'd pass on this to be honest. We used to print photos on our solvent, but it's an Epson S80600 with gigantic gamut compared to the BN20 and far clearer print quality.
We've moved all photos/posters back to an aqueous. The right tool for the right job.
If you reaaaally want to do this, Sihl 3672 made our clients very happy and was solvent compatible.
