Want your A1–A5 print to look crisp? Run this checklist before you export.
1) Start with the best source
- Use the original file (not a screenshot or social export).
- Prefer RAW → export to PNG or high-quality JPEG.
2) Target size & PPI
- Aim for 300 PPI if viewed up close; 150–200 PPI works for posters viewed from a distance.
- A-series at 300 PPI (approx pixels): A3 3508×4961, A2 4961×7016, A1 7016×9933.
3) Clean before upscaling
- Reduce noise and fix exposure/white balance.
- Heal obvious artifacts before enlarging—they only get bigger.
4) Upscale
- Use 2–4× upscale to hit your target pixels. If you’re short, upscale first, then downsize to the exact print size.
5) Sharpen last (lightly)
- Apply subtle output sharpening after you reach final size.
6) Color & profile
- Use sRGB unless your print shop asks for CMYK.
- Avoid oversaturation—prints are less luminous than screens.
7) Export
- PNG for graphics/flat color; JPEG (quality 90–100) for photos.
- No watermarks or multiple compression passes.
Tip: PrintUpscale gives you a ZIP with A1–A5 sized PNGs, ready to go.
