i own a summa dc3, i’ll try to answer as best as i can.
materials:
the manual says only to use 3m 50 series or 100 series in white or clear.
looking at the price of the media and the ribbons that’s not a good idea, i know it’s the customer that’s paying in the end but you’ll price yourself out of the market if you do, i asked my supplier if they had anything that as compatible with it, they didn’t know so we agreed that they would send me 1 square meter of every digital white they produced, we then printed a file on all of them (thin line, spot colour and a photo) then compared all the prints and made our choice, of course we had to send the printed materials back to the supplier who then made their own ratio on it and used it in their tabels for compatibility, we ended up with a digital soft calandered white, wich we use for everything, it’s suitable for a wrap and priced low enough that we can even use it for those “use and throw away” plates.
the media it can cope with has to be 1meters wide, no more and no less.
maintenance is reduced to cleaning the “sticky roll” (cleans the vinyl just before it prints it’s first band) once a day
the summa can:
-print and cut
-print only
-cut with opos
it cannot:
-cut only like a plotter (tried it and turned out an expensive joke: it goes beserk on the media totally destroying it) not funny 👿
the software that it runs on is called color control, it’s a rip software like mistral or the production managers of say flexi, omega,
omega does not support the dc3
flexi does (when given the propre profile)
it prints suberbly up to an apparent 600 dpi, very vivid colours and
durable. it’s totally self automated: switches it’s own colors, aligning the media,… it can run actually unattended (not like some inkjets that only say in the manual it can and in real life cannot)
and the greatest plus of the machine is that it’s a summa, doesn’t break an runs steadily for ages, not to forget the world’s best tech support, all errors and hitches are solved by email free of charge.
some of the work i made with the summa on the digital white from my suplier can be found on the folowing links:
