Is blurriness on the proof normal or should I be concerned about the final product?

A little blurriness on an online proof is normal and does not reflect how your final print will look.

• Not a quality gauge: online proofs do not indicate the actual quality of the printed work.
• What they show: they depict the trim edges and confirm that nothing is missing from your layout.
• On-screen softness: low-resolution previews can look soft on screen even when your print file is crisp.
• Real concern: if an element is genuinely low resolution in your file, that is worth fixing before you approve.
