A New Watermark

The purpose of this change was to strengthen the paper and to give it a more uniform thickness. The old double line watermark covered too much space and made the lettered area quite a bit thinner than the rest of the paper, which caused variation in the shrinkage of the paper. The new watermark was also smaller, occurring 400 letters to a full sheet instead of 360.
