How to use it
- Choose a still image or select a page from a supported PDF.
- Set the finished width or height in millimetres, paper size, margins and overlap.
- Review every sheet in the arrangement and optionally add cut marks, labels and a calibration sheet.
- Create the PDF, print at Actual size / 100%, and measure the calibration square before assembling it.
A 370 × 222 mm image fits across two A4 portrait sheets with 10 mm margins and 10 mm overlap when marks and labels are off. The optional 50 mm calibration square adds a separate sheet.
Details & limits
Images: 10 MiB / 20 MP. PDF: select one page from up to 25 MiB / 100 pages, rendered to bounded pixels. At most 100 output sheets including calibration. Print at actual size.
Why does the printer's Fit to page setting matter?
Fit to page changes the scale established in the PDF. Use the chosen paper and Actual size / 100%, then measure the 50 × 50 mm square. Printer margins and physical output still need checking; enlarging a low-resolution source cannot add image detail.
