The practical print test
Print quality depends on pixel dimensions divided by the physical size you want to produce. For close-viewed pieces, 300 PPI is a common target. Large signs can often work at lower effective PPI because people view them from farther away.
- Use 300 PPI for business cards, labels, brochures, and photo prints.
- Use 200 PPI as a warning zone for many flyers and posters.
- Use 150 PPI or lower only when viewing distance and material make it acceptable.
