this is a bit curve ball...
we job out to offset printers several short (their min order is x250) cmyk A2 poster runs weekly, always required trimmed to bleed (borderless)
i would like to bring this inhouse to work our own (unpurchased, undecided) lfp, especially as clients often don't want 250, only 100 or 150 A2s
we also get a couple of other primarily short (1-10) run poster jobs (A1, A0) & the odd sticker etc which we also job out & could bring in house & build upon (we run km6500 and provide design and print services)
some posters are displayed on small billboard hoardings for up to a couple of weeks, they are glued up with wallpaper paste & brooms, but probably most are displayed internally. i havent tested but was advised these should be ok (printed on epson aqueous ink wouldn’t run because microporous paper would trap ink)
I see my options as a) aqueous pigment ink epson T7000, 44", I believe can print approx 30m2 per hour @720x720 (72m2 @ 720x360!) only cost $10k (with rip & 3year warranty)

epson xd pigment ink is 30c per ml or $133 for equivalent 440ml, microporous (water resistant) paper ive been quoted $2 per m2 140gsm coated, dealer says 2ml ink per A2. ie approx total $1.10 per A2 or $4.40 per m2+machine (which is just ok, as 250 A2 offset costs us $240), but very importantly T series can print trimmed to bleed, as the cost to hand trim hundreds of A2s is $s prohibitive. fwiw 3rd party inks are avail about half price
I would build a custom catch tray/stacker.
But I would prefer the versatility and the lower running cost (?) you only get with solvent.
option b) rs/xc/vs ecosol with, wait for this, running A2 width stock (that is when running A2 jobs), machine printing borderless (i believe only some rips allow this) and having an easily replaceable sacrificial substance (blotting paper?) gently adhered to platen either just inside A2 paper path or very very close, to soak up overspray. Thus printing trimmed to bleed posters ready for immediate distribution. Please could anyone suggest if or how this could work?
I calculate VS/XC may only print 30 A2 per hour at 720x720...? (ie 7m2 or 75ft2)
I appreciate all comments but just because it hasn’t been done b4 (not that i know anyway) doesn’t mean it cannot be considered
we also have very limited space so if going solvent VS preferred. ive roughly converted AU$ into US$

ps epson gs6000 (mutoh) came out with a borderless kit but I dont think it was well received
