For my opinion interesting too: the improved scratch resistance (they say about hard solvent level) and the new curing system which will not stress the media so much anymore. And more heat stable print heads to print with more color consistency. This will solve some other problems too.
We have got our Latex 360 Demo-Unit (we are dealers) wednesday, but without ink
. I hope the ink will arrive today.
Also interesting: there are three models, for example a cheap 54" with the printing speed around the Latex 260, but with the improvements of inks and curing too.
