anat ii imposition

PDF Document · PDF

What was done:
  • Source PDF: 90 pages
  • Pages reordered to match your exact imposition layout:
    • Each group of 18 pages forms a print sheet set (front row + back row)
    • The output PDF pages now flow in the sequence: 1, 3, 5, 7, 9, 11, 13, 15, 17, 6, 4, 2, 12, 10, 8, 18, 16, 14, 19, 21... and so on through all 90 pages
  • All 90 pages are included, no duplicates, nothing missing
