I'm curious.
What type of stuff you guys are printing with these these ink systems and the WF1100? What kind of paper do you use for stickers?
Also, from what I gather you use UV pigment inks for transfers (sublimation?) and the dye inks for stickers/photos?
I print vinyl decals, posters & mini banners using a CISS loaded with pigment inks from
http://hotzone360.com/index.html.
I also sell an aqueous ink printable vinyl by the roll that I cut to size and then either create an outline in Adobe to countour cut (shaped decals) or hand cut (square decals) after I laminate them with lamination film or a urethane spray paint for plastic.

Some people like the Cobra Ink resource because the sales guy offers lots of one on one support and states that Cobra Ink invented the CISS, but frankly the only reason I don't see the value in that is because I've never needed any help/support or had a complaint with the Hotzone360 product to require me to call anyone for anything other than to order more ink. No color adjustments, no clogs, no leaks, no complaints... the price from Hotzone360 is much better too.
