Why this site exists
Print questions often mix pixels, DPI, PPI, paper size and crop into one confusing answer. Print Prep Lab separates those decisions and shows the inputs behind every result.
The initial audience is students, photographers, artists, Canva users and print customers who need a reliable plan before placing an order.
What this site does not promise
A browser calculator cannot inspect a printer, ink, paper profile, sharpening method or production tolerance. Results are planning guidance and should be checked against the provider's specification.
