InkTrap

letterpress-ink-trap-calibrator.hub2.day is a focused independent web utility built around InkTrap: Letterpress Ink Trap Calibrator.

What This Site Does

A tool to help letterpress printers determine optimal ink trap thickness and technique based on paper absorbency, ink type, and pressure settings.

Who It Helps

Letterpress printers, bookbinders, and craft artisans working with raised type.

Why This Exists

Ink trapping is one of the trickiest parts of letterpress printing. Every press is different, every paper behaves differently, and every ink batch varies. This calibrator helps you find a starting point based on your materials.

Technical Approach

The calculator uses a weighted algorithm based on decades of printmaking knowledge. Paper GSM, ink viscosity, and pressure level all affect trap depth. The drying time calculation accounts for absorbency and environmental factors.

Future Development

Potential features include community-contributed profiles, expanded paper database, and integration with printmaking supply guides. Always local-first, always private.
