Fig. 2, which are provided on the side of a printing plate for the usual static circumferential
and/or lateral register adjustment).” (Specification, page 6, lines 14-17.)
The register marks in Palmatier would be transferred to the web from the printing
plates by means of the intervening blanket cylinders, and the transfer would occur at the
known speed of the printing press, as measured by tachometer 24. Precise
circumferential registration would result in the time between subsequent register marks
reflecting the speed of the printing press; misregistration would result in register marks
being sensed at times other than those expected.
We thus might be inclined to agree with the examiner that an operational system
could be effected using the sensors disclosed by Palmatier, such that operation of the
system falls within the ambit of the instant claims. However, we do not find any disclosure
or suggestion along those lines in the reference.
Palmatier takes the speed of the press into account in correcting the circumferential
misregister between the plate cylinders and blanket cylinders. See, e.g., id. at column 6,
lines 17-46. Process control computer 70 determines a control signal output based on
both circumferential misregister and the speed of the respective plate cylinder, since the
misregister is corrected taking the rotational speed of the plate cylinder into account.
However, Palmatier’s disclosure is entirely consistent with measuring misregister in
distance -- how far the plate cylinder must travel in one direction or another to correct
