Hi, I have scanned a few large format drawings, the largest one is on a paper size of 53" x 31". They where done like this mock up shows.

The scanner is a hp scanjet 4600. I took 10 portrait scans which overlapped each other and four landscape scans, which overlapped each other and the 5 bottom portrait scans. Example of one of the portrait scans below.

When all the scans were done, they were then stitched together to make a full drawing and then cleaned up, this drawing was done in 1947 and is on a paper 40" x 27" and this copy was probably done when the original was getting a bit tiered, hence all they grey between the lines. The photo shows most of the drawing stitched up, but I haven't ever finished it completely and even this still needs some bits cleaning, but it is a time consuming job, others I've done have not needed much cleaning at all.

Regards Nick.
