Create Custom Plate

Numbers, letters, or symbol name (star, arrow, triangle, heart, diamond, circle, square). You can also use symbols: moon, sun, check, x, target, squareDot, dot, leaf, wave, shield and shapes: pentagon, octagon, rounded-square, annulus, oval.

Same seed + parameters = identical plate

Nothing measured yet

Generate a plate in the Lab and its four score components, and the ΔE through each simulated deficiency, appear here.

The standard thirty-eight

Twenty-four numbers, six letters, four symbols, two shapes and two traceable paths — the composition a printed book uses, built from a single seed so it is the same every time.

PNGRaster

Rasterised at the plate's own size on the chosen card stock. What you paste into a slide or a document.

SVGVector

One circle per dot, so a plate scales to any print size without resampling. Around seven thousand of them.

SeedsReproducible

The seed, palette and settings behind every plate on screen, as one text file — enough to rebuild the batch.
