Complete journal pages
Print the full page at its selected preset, verify the calibration square, and trim only if your binding requires it.
Print guide
Pepys promises ±1mm accuracy only when you print at 100% / actual size, keep the calibration square correct, and use the same paper size you selected during export. Follow the steps below.
Five checks for true-size printing
- 1
Export with the intended physical preset
Export the page or sticker sheet using the same physical paper preset you plan to load into the printer.
- 2
Choose 100% or Actual size
Set print scale to 100% or Actual size; Fit to page, Shrink, and Fill change the physical dimensions.
- 3
Use bordered printing for accurate edges
Disable borderless mode when exact dimensions matter because printer overscan enlarges content beyond the paper edge.
- 4
Measure the calibration square
After printing, measure the labeled calibration square with a ruler and confirm both sides match before cutting or binding.
- 5
Finish the correct output type
Keep full pages intact, trim planner or scrapbook pages as needed, and cut sticker-sheet pieces along their guides.
Print at actual size
- Open the exported PNG in your printer app or system photo viewer.
- Use the image at its original pixel size. Never use 'Fit to page' or 'Shrink to fit'.
- Choose bordered printing (with margins). Borderless mode can silently scale the image.
- Choose the same paper size in your printer settings as the paper size you selected in Pepys.
Check the image size
- Pepys PNGs are rendered from the selected paper size at 300PPI.
- The pixel dimensions change with the paper you choose.
- If a printer app shows a size or scaling option, keep it at original size / 100%.
- If printed dimensions are off, the printer app is still scaling the image.
Measure the calibration square
Use a ruler to measure both sides of the labeled calibration square on the printed output. If either measurement is wrong, stop: the printer or print app has scaled the file, so correct the settings and print again before trimming.
About borderless printing
Borderless mode usually enlarges the page slightly (overscan) so ink reaches the paper edge. That breaks physical accuracy by 2–3mm. Pepys' ±1mm promise does not apply to borderless prints — use it only when exact size doesn't matter.
Sticker-sheet exports
- Split export produces a base-page PNG and sticker-sheet PNGs sized for the paper you selected.
- Sticker sheets keep sticker sizes unchanged and only arrange them on the selected paper.
- Stickers keep a 3mm safe margin from the paper edge and 3mm spacing between each other.
- Print the sticker sheet on sticker paper, then cut along the gray dashed lines.
- Cut lines follow the white die-cut border of each sticker — scissors or a craft knife both work.
Tips
- Print the base page on your journal paper first, then stick the cut stickers on top.
- Text placed above stickers in the editor will be covered by the physical sticker — Pepys warns you before export.
- Low-resolution photos print blurry; the editor shows an effective-DPI warning below 150 DPI.
What changes by output type
Planner inserts
Match the exact insert preset, then trim and punch only after the calibration measurement passes.
Scrapbook pages
Preserve the complete photo-and-text composition at the chosen page size; do not let Fill crop the outer layout.
Sticker-sheet imposition
The sheet rearranges pieces without resizing them. Print on the selected sticker paper and cut along the generated guides.
