Heuristic: uses ΔE00 vector, gray balance (G7‑style L*), overprint heuristics, substrate profile weights, and O/G/V distribution by hue.
2) Patch Grid • CSV • Heatmap • Auto‑Balance
Click any cell to edit Target/Press LAB. ΔE00 auto‑updates.
3) Resolve‑Style CCM (3×3) from Paired Charts
Load two charts (Target & Press) with same patch order to estimate a 3×3 color correction matrix in CIE Lab (linear regression).
CCM: —
Tip: 24‑patch chart (Calibrite/Datacolor) on press & proof → generate corrective CCM. Save per stock/inkset.
4) Pantone / Brand Library (Local)
Use like PantoneLIVE locally: store approved LAB per substrate/method. Import/Export to share. Loaded: 1089 Pantone Colors
5) Utilities • ICC Soft Proof • Live Spectro Bridge • SOP • Report
ICC Soft Proof (RGB Matrix/TRC v2)
Load an RGB display/printer profile to improve swatch previews. Supports ICC v2 matrix/TRC (rXYZ/gXYZ/bXYZ + rTRC/gTRC/bTRC). CMYK LUT profiles require CSV DeviceLink import below.

Live Spectro Bridge (Folder Watch)
Connect a folder that receives spectro CSV exports (e.g., X‑Rite eXact). New files are auto‑ingested into the Grid. Uses the File System Access API when available; otherwise, drag & drop files below.
