Ink Drawdown
The colour on its substrate, with three pictures beside it. Variator shows what a ΔE00 tolerance looks like in every direction. Snowflake finds your tolerance on each axis: adjust each arm blind until the difference is just acceptable, then reveal the values. Concentration simulates the ink at 50–150 % strength, as it drifts on press. Click any patch to see it beside the aim.
What you see depends on your display; the line under the square says whether an instrument has checked it.
