PRACTICAL WORKSHOP GUIDE
How to print and assemble your poster
Follow these essential printer settings to guarantee that all tiled pages align with 100% precision.
The #1 Most Important Rule: Print at 100% Scale (Actual Size)
In your PDF viewer print dialog (Adobe Acrobat, Chrome, Apple Preview, etc.), always select “Actual Size” or set Custom Scale to 100%. Never leave “Fit to Printable Area” or “Shrink to Fit” enabled, as that will reduce each sheet slightly and make grid lines mismatch!
Check Printer Settings
- Page Scaling: 100% / Actual Size
- Paper Source: Match your paper (A4 or US Letter)
- Quality: High / Photo for richer contrast
Trim Only 2 Edges
Don’t trim all 4 borders of every page! To take advantage of the overlap tabs:
- Cut off the left and top white margins.
- Leave the right and bottom overlap tabs untouched as glue anchors.
Assemble Row by Row
Lay out Row 1 on a flat clean table or floor. Apply a thin line of standard glue stick or double-sided tape along the overlap tab. Align sheet #2 over sheet #1 using the printed alignment marks.
Mount on the Wall
For a durable display, mount the completed poster on foam core board, cardboard, or directly onto drywall using painter’s tape, poster adhesive putty, or poster hangers.
