Claim 0:
1. A method of preparing a print job for a printing operation, which comprises the steps of:
providing at least one first data set associated with the print job and multiple reference data sets associated with a plurality of reference jobs, wherein the providing step contains the sub-step of providing multiple mutually complementary data sets as the multiple reference data sets for each one of the plurality of reference jobs;
with a digital computer, digitally creating a unique fingerprint for the first data set and digitally creating a unique fingerprint for each one of the multiple reference data sets;
saving the fingerprint for the first data set together with the first data set or in connection with the first data set;
for each respective one of the multiple reference data sets, saving the fingerprint for the respective one of the multiple reference data sets together with the respective one of the multiple reference data sets or in combination with the respective one of the multiple reference data sets;
automatically filtering the multiple reference data sets of the plurality of reference jobs to provide a second data set, wherein the step of automatically filtering uses the fingerprint generated for the first data set and the fingerprints generated for the multiple reference data sets; and
using the second data set in the printing operation as a replacement of or an addition to the at least one first data set;
wherein the multiple reference data sets stem from earlier print jobs printed on a same printing machine or on different printing machines of a group of machines; and
wherein complementary in the providing step means that the multiple reference data sets associated with a respective reference job combine to form an essentially complete data set for a printing operation of the respective reference job, or complementary in the providing step means that that the multiple reference data sets associated with the respective reference job complement one another to form a data set used for the printing operation.
