Model how a filter shapes light, then design the recipe.

Lightprint combines dyes on a base, shows how the mix filters a light source, and searches for recipes that meet your targets: blue light and hazard reduction, melanopic reduction, transmittance and color.

• LensesDye recipes for PC, MR-8 and CR39 lenses against partner design targets for premium, everyday and computer lenses.
• ScreensSee how a filter performs on real displays, from measured iPhone, Dell and KSF and QD backlight spectra, including blue light reduction and color shift.
• LightingModel the same filter under daylight and LED sources (D50 to D75, F11, LED).
• Ideal filtersExplore ideal absorption notches across the visible spectrum to find the best filter shape before a real dye exists.
