Just to reiterate... solvent, and eco-solvent need ventilation. No manufacturer will tell you otherwise. The chemicals in solvents cause Cancer / not can, but do.
Most solvent/ecosolvent (Check your MSDS sheet) allow 20 PPM exposure... A few places did a study with printing without any ventilation, measured the air and after 20 minutes... The air ranged from 20 PPM, to 200 PPM, and went up even further after the 30 minute mark.
Hospitals/schools are starting to only allow xx feet of prints because they've found even just the prints cause defects in children.
Now remember, not all ink is created equally. Rolands new Eco-solv2/3 ink is supposed to be friendly and safe in hospitals and schools. Them are the only 2 I know of that are green-guard certified, and only two I would trust without ventilation.
depending on how big of a town you are, it may not benefit you to purchase a printer. You probably see you could save 75-80% buying your own materials / inks, etc... But once you factor in ink, time to print, time to laminate, time to applicate,, the machine, wear and tear, other materials, etc... It likely wont be.
forget a hybrid... Depending on the length your coro needs to be up, you can get material as cheap as 15 cents a SQFT,(Cheap crap that'll be up for a week/month max) to good stuff that'd last longer than the coro for 50-.75 a sft. a 4x8 = 32 sqft... so you're adding $5-$25 (Depending on how long you need it to last) per 4x8 sheet. + Labor cost etc. Unless you plan on printing hundreds of sheets, buying a $80-100,000 printer doesn't make sense compared to a $12-20,000.
As for laminating banner... No point! Banner is the cheapest material you can purchase. Inks generally last a few years in the sun without UV protection depending on sun exposure... so if theyre up for 2 weeks, then put away... they should be fine for next year. But even if you have to re-print them every year... You're looking at a couple bucks in Material. you should still buy a cold laminator for applying to coro / laminating other prints you may be doing... but now you're taking up more space.
