Every slab gets a reading

Every slab that comes off the line is read at a fixed point and compared with the first slab of its production run. It passes below ΔE*ab 0.4, five times tighter than the ΔE 2.0 commonly quoted for quartz batch variation. A slab that reads higher goes back for rework.

Before printing, each blank slab is read at six random points and the average is logged against its serial number. If the blank drifts, the print drifts with it.

Want the numbers? We can send the reading of every slab in your order before loading. Ask for them with your quote.

Colorimeter app screen comparing the reference slab with the measured slab: L*, a*, b*, C* and h values, a ΔE*ab result and a green PASS bar — The app compares each slab with the first slab of the run.

Handwritten daily production log with serial numbers, slab size and blank-slab L*a*b* averages; process settings are masked — Daily log: each blank slab is read and logged by serial number. Process settings masked.

Handheld colorimeter, d/8 geometry, 8 mm aperture, D65/10°; manufacturer-rated repeatability ΔE*ab ≤ 0.03. Two readings from 29 September 2026, same design: 0.23 and 0.31. In-house production measurement, not a third-party report.

Color codes

Every design has a fixed 10-digit color code; a code already issued to customers is never reassigned

Code format: release date YYYYMMDD (8 digits) followed by a 2-digit sequence within that release. Example: 2026030102

Repeat orders

Written batch-matching procedure for repeat orders of the same code In preparation

Not published yet. Ask us how a repeat order of your code is produced. We do not claim that production batches show zero color difference.

Checklist

Seven checks when slabs arrive

Print this list for your warehouse team.

01
Crates
Photograph crates and labels before unloading. Note any damage on the delivery receipt.
02
Quantity
Count slabs per color code against the packing list.
03
Labels
Check that the color code on each slab or crate label matches your order.
04
Color
Compare under daylight with the physical piece you approved.
05
Edges and corners
Look for chips along all four edges.
06
Face
Check the face under raking light for scratches or marks.
07
Thickness
Measure thickness at several points on each slab.

If something is wrong

Send photos of the crate label, the whole slab and a close-up of the issue, with your order reference, through the contact form.
