The following will support 1748 patches assuming I have the A3+ size correct: printtarg -v -iCM -h -a0.6 -t360 -p333x482 testname Given that, targen just needs to produce a 1748 patch target: targen -v -d2 -G -f1748 testname Be sure to measure your printed target to check for unexpected scaling problems. Suggest scanning with a double-sided ruler (search archives for discussion of this) with 8.22mm patch size (measure 10 rows and divide by 10).
