PrintReady is a free, browser-based toolkit for print production.
Unlike most online tools, everything runs locally — your files are
never uploaded. It bundles a PDF preflight checker, CMYK soft-proofing
with a real ICC profile (not a formula), imposition, crop & registration
marks, and 13+ calculators (bleed, spine, DPI, n-up…). 17 tools, no
login, free, EN + KR. Differentiators: real ICC color, full client-side
privacy, and an all-in-one print-prep workflow.
