Question
What file resolution and color space should I use for postcard printing?
Answer
For postcards, set photographic images to 300 DPI at the final print size, and prepare your file in CMYK, the color space used for printing. Working at 300 DPI keeps photos crisp, while CMYK keeps your printed colors close to what you designed on screen.
| Setting | Recommendation |
|---|---|
| Resolution | 300 DPI at final size |
| Color space | CMYK for print |
| File type | Print-ready PDF |
- Size images to the final card, then set them to 300 DPI
- Convert artwork from RGB to CMYK before exporting
- Very bright RGB colors can shift in CMYK, so preview before printing
- If your project needs a specific color profile, confirm it with your printer
