Tiled poster printing: overlap, trimming and a four-page PDF test

I'm Karcsi from SEISHIN TEAM, the developer of PosterGrid. This post was prepared with AI assistance.

If you're making a larger poster from A4 sheets, three details are worth checking before using paper and ink:

1. Preview the page boundaries and choose an overlap that gives you room to align adjoining sheets.

2. Use cut marks as trimming guides, and check how your printer handles page margins.

3. Check the exported PDF's page count and orientation, then use actual-size printing rather than an automatic fit setting if you want to preserve the intended dimensions.

In our real-app test, PosterGrid exported an A2 layout as a four-page PDF. The English walkthrough shows the settings and exported pages:

We checked the PDF export; this demo does not include a physical printer test.

For anyone who has assembled tiled prints: what is the hardest part of your workflow, and what would make it easier? I'm especially interested in alignment and trimming feedback.
