Because a master was made according to
a larger size than the original, the edges of
the original were processed as shadows.

and perform the master-making operation
again. Or attach tape as described below

making the master?

new master. Or pull out the Print Drum and
attach cellophane tape to the damaged
section on the master. However, if
attached with cellophane tape, a master
may not been properly sent to the Master
