I’m related to a professor of design, and he recommends White House Custom Color (https://www.whcc.com/) for prints. I think you may need to upload a sample of your “work” to gain access, at least last time I made an account.
I actually have some of his prints from an exhibition hanging on my wall (via 3M adhesive strips), printed via this service. These are printed on a ~1/8” board and have a glossy protective finish. They’re super high quality.
As for whether the price is reasonable...I’ll leave that to you and your utility function.
A little different from posters, but if you're looking for something a little more durable I've had success with CanvasChamp for canvas wraps: https://www.canvaschamp.com/

Good quality printing, and very
I'm curious about this as well. If no service exists, does anyone happen know what types of printers work best for these? I'd be willing to try it myself if I knew where to start.
Until the pandemic I produced the prints myself, but now I use print-on-demand companies like Printful or Gooten. There are similar companies out there, but these are a good balance of price and quality.
