Orthogonal distortion-check grid / LETTER
A good fit for your idea?
Scale, fold, trim and front/back alignment are different checks. Follow the procedure for this sheet.
Inside this edition
A printing diagnostic, not a certified measuring instrument.
10 mm squares: compare equal horizontal and vertical spans with a ruler. Check for bowed lines or uneven spacing.
From file to finished page
- Choose the paper size loaded in your printer and open the matching PDF.
- Print at actual size and measure the 50 mm reference line before using physical measurements.
- Use the selected sheet’s printed guides and labels for the task. Choose the page or layout that matches the work instead of printing every variant.
- Keep a master copy and work on a duplicate when annotations or repeated use are required.
Printing and use notes
Make one trial on ordinary paper before using special stock or preparing a batch. No physical test result is claimed.

KEEP THE IDEA GOING
A few more possibilities.
Paper & writing
Duplex alignment trial sheet
Compare front and back placement in a two-sided trial. Follow this sheet’s duplex procedure rather than applying a fold-only check to a printing-alignment problem.
Paper & writing
Fold-alignment test
Compare a crease with the supplied center and mirrored marks. This is a single-sided fold-alignment check, distinct from the duplex trial sheet.
