Hi over the years i operate few large format printers flatbed : Vutek QS series, Afga Anapurna, Acuity Advanced, Onset r40, and many other out of date solvant printers...In roll to roll i operate Hp Scitex, Mimaki, Kodak, Jeti Gandi, Fuji Uvistar UV 197 inch.
I must say it depends what kind of customer you got, alot quantity orders? or alot small quantity customers? Whats the substrate you using more often and are you doing alot 2 side printing sheet? are you looking for a hybrid flatbed-roll to roll (like the vutek series QS and GS) or you looking for a dedicated flatbed , or a dedicated roll to roll printer?
My favorite Flatbed i would pick for heavy duty high quality production :
Onset X (with the automatic stacker)
I run an Onset R40 it was the previous model and im telling you thats the best flatbed i ever operate, the Onset X its their last release.
For a roll to roll printers i would pick without any hesitation :
Uvistar 2 UV 197 inch wide
with this printer you can print a 197 inch banner wide, 2 side printing without cutting ,,no waste... the entire roll dosent move much i was impress very fast. Easy maintenance A++++
For the hybrid printers, i would pick :
Afga Anapurna 126 inch wide model
If you have a Vutek you wont be too much lost with this printer, very similar concept with improve feature like the tension is more stable, and you have safety sensor that stop the carriage at any contact , im no more a fan of EFI vutek for many reason i would pick the Afga.
hope it help good luck.
