Coated paper can support crisp image detail; uncoated paper offers a different surface feel and ink response. Compare representative printed samples when color matters.
Weight is one part of the choice
Gsm measures mass per unit area. It does not uniquely determine thickness, opacity or stiffness. The same gsm can behave differently across paper grades.
Check both sides of the page
Consider show-through, color contrast and how text and images interact on facing pages. A heavier sheet is not automatically the best reading choice.
Avoid fixed conversions
Lb values depend on the paper category and basis sheet. Do not use one fixed gsm-to-lb conversion for every stock. Confirm the actual grade, availability and thickness before calculating the spine.
General preparation information. Project requirements, materials and services must be confirmed; this is not a manufacturing commitment.
