Print and inspection procedure

  1. Use US Letter paper and print at Actual Size / 100% with no scaling.
  2. Confirm all six pages are present and no row or column is clipped.
  3. After cutting, verify exactly 2,048 unique official words and four blanks.
  4. Set every blank aside before mixing; blanks are never entropy outcomes.
  5. Reject slips with visible or tactile differences that could affect selection.
  6. Do not use an incomplete set for the recommended with-replacement method.
