Prepress Toolkit

PrintKit is a fast, offline toolkit for print and publishing professionals. Calculate everything you need before a job goes to press — no internet required, no clutter. Five built-in calculators: Pages & Sheets — work out how many sheets a job needs from total page count and imposition. Bleed & Trim — get the final trimmed size after removing bleed on every edge. Ink Coverage — estimate total ink area from coverage percentage and number of colors. Spine Thickness — calculate book spine width from paper weight, page count, and bulk factor. Folded Size — find the finished panel size after any number of folds. Every result is saved automatically to your history, so you can refer back to past calculations anytime. The app works fully offline and stores all data locally on your device. Clean, native iOS design. Built for designers, prepress operators, and print buyers who need quick, reliable numbers.
