How to prepare images for print
Check dimensions, format, and margins before PDF layout.
Start from the final physical size, calculate required pixels at 300 DPI, and keep line art in a lossless format until the final PDF is built.
Steps
- Calculate required pixel dimensions.
- Resize only from a sufficiently large source.
- Inspect edges, grayscale, and thin lines at print size.
How to verify the result
Example: check whether 2550 × 3300 pixels is enough for an 8.5 × 11 inch page.
Check: This is a calculation aid, not marketplace certification or a print proof.
Frequently asked question
Does changing metadata increase real DPI?
No. Effective print DPI depends on actual pixel dimensions divided by print size.
