Run Size Vs. Total Printed

I just did the math and your note is from Run #2 and serial number plate position should be D2..
Both Runs #1 & 2 are full 100,000 sheet runs.
Run #3 is a partial Run of 10,000 sheets...

Note; the serial number skip- numbering is 100,000 per plate position on all 3 Runs...

Since Run 3 is only 10,000 sheets, each COPE Plate Position skips the first 90,000 serial numbers and use the last 10,000 serial numbers per plate position..

Example:
Run #1 Plate Position A1 assigned serial numbers are 00000001 to 00100000

Run #2 Plate Position A1 assigned serial numbers are 03200001 to 03300000

Run #3 (10,000 sheet run), A1 assigned serial numbers are 06490001 to 06500000 ---(06400001 to 06490000 not used)...
