Generate a LUT Calibration Board

A calibration board arranges the recipes of a colour mode as printable patches. After printing and photographing it, LUT Extractor can write the measured colours back into a LUT.

Parameters

• Colour Mode: selects the recipe set and page count; BW, 4-colour, 5-colour Extended, 6-colour, and 8-colour modes are supported.
• Patch Size: 3–10 mm in 0.5 mm steps. Larger patches are easier to photograph but enlarge the board.
• Patch Gap: 0.4–2.0 mm in 0.01 mm steps.
• Backing Thickness: 0.4–3.5 mm in 0.08 mm steps.

8-colour mode exposes Full Export. 5-colour Extended and 8-colour calibration may require multiple pages, so their result is delivered as a package rather than pretending every recipe fits one board.

Output

After generation, the right side shows the complete preview and per-layer images. Open a layer thumbnail to inspect it at full size. Slicer actions use the printer, nozzle, and slicer selected in System Settings.

The colour mode and page selected during extraction must match the generated board. Keep the positioning border intact and never combine photos from different calibration modes in one extraction session.
