There are portable scanners around designed to scan large art works
for museums etc. I attended this workshop and was very impressed.
I don't know about commercial operations in the USA but guess there must be
people with similar large scale scanners.
Alternatively a multi-shot Hasselblad camera on a motorised stand, with
proper lighting or flash can be used to take two or four, 200-megapixel
images and produce a large colour-corrected image stitched together in
I've done this myself with a large wedding veil but never attempted to print
the image. Unlike hi-end scanners the lenses are not strictly designed for
producing images for stitching but the results I got were good.
There are examples of my 200 megapixel shots on Google Cultural Institute to
give you an idea of what the camera can do.

to zoom in.

Subject: [SCIART] Large-format scanning for prints
Hello, everyone, I am exploring the feasibility of making prints of my large
-scale charcoal drawings (84"w x 48"h). Can anyone offer insight, or perhaps
recommend a US vendor who offers these services? Many thanks as always,
