I had this giant drawing of Psalm 84 and wondered what it would be like to create a reproduction.
Ended up taking it to a local printer that scanned the work on an oversize flatbed, then stitched it together. They also printed it out, which looked decent, but... the original has a bit more life. Next time, going to try visiting a printer that has a larger-scale flatbed scanner that's used for paintings and other big work.
Mostly, the printed version added grey into the paper color... and dulled it all down slightly.
