Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
HA! My first job was at a poster/banner shop that also did trade show type printing. We would be able to hand print banners and poster board at 48" tall by much longer than 96" long but I can't remember exactly how long. The largest manual press (single color at a time) had a squeegee bar across the top that it was mounted to and you would pull is along at a fixed angle. Did great spot color prints, but not for 4 color process work. Print that color, and stack it. Let it dry and come back and print the next color. We had some auto clam shell presses also.
