Calibration Tone Curve
The measured tone reproduction curve bows away from the ideal diagonal and is pulled back onto it as calibration converges, the residual bar beside the plot falling into the tolerance band.

A target cross sits inside nested tolerance ellipses while a measured sample point drifts out past the acceptance limit and walks back in, a scale marker below tracking the same delta.
A measured density trace clears and is laid down again step by step across the eight-patch wedge, climbing from the highlight end to full density and holding there.
Four halftone cells hold nominal dot outlines while the printed dots inside swell past them and a gain bar under each tone rises to the measured value.
A fixed reference chromaticity hull contains a device gamut triangle whose primaries collapse inward and push back out to the boundary while a coverage bar tracks the enclosed area.
Three process channel traces swing out either side of the neutral axis and flatten back onto it in sequence as grey balance is recovered.
Eight ink key slots across the press width close down for make-ready and step back open one zone at a time until they match the density demand profile drawn over them.
A spectrophotometer head returns to the chart origin and tracks back across a grid of measurement patches, each column blanking just ahead of it and registering as read once it passes.
A destination lookup lattice relaxes onto the regular source lattice beneath it and warps back into the profile's shape, its corner nodes travelling furthest.
The press trace lifts clear of the dashed tolerance band around the proof curve and descends back onto it while the match bar beneath refills.
Two gamut hulls side by side: on the left out-of-gamut samples are clipped hard back onto the boundary one after another, on the right the whole sample cloud is compressed inward as a set.
A measurement cursor sweeps the wavelength axis while the reflectance trace exchanges one sample's curve shape for another over the middle of the sweep.
A rail of library swatch tiles shuttles either side of a fixed reference aperture, the aperture closing and the match score refilling when the selected tile registers inside it.
Four stacked process ink layers clear and rebuild from the bottom up while a total coverage rule rides the top of the stack back to its headroom under the dashed limit.
An illuminant sample runs along the locus away from its reference tick and back while the lock crosshair opens and closes around it and the temperature marker tracks below.
