Expert Tip
Mix interleaves pages from two PDFs. The standard pattern (ABAB) creates duplex-ready output from separate front and back files.
Both source files must have the same page count for 1:1 interleaving. If the counts differ, excess pages from the longer file are appended at the end.
Duplex Interleave
Interleave separate front and back files for duplex printing.
