I’m after training that tightens color control and translates to fewer pulls and faster setups — beyond the intro stuff. I run a 6-color 40" Heidelberg with closed-loop and an X-Rite eXact; has anyone taken G7 Expert, Fogra PSD, or another course that genuinely dropped deltaE and waste?
G7 Expert moved the needle for us: rebuilt per-stock NPDC curves, locked the Heidelberg closed-loop to CRPC6 aims, and turned on eXact averaging (‘don’t chase density, chase gray’), which cut make-ready about 20% — no more dog-chasing-its-tail pulls… If you’re bound to ISO 12647, Fogra PSD/PSO is equally practical; G7 Expert Casa Abierta Virtual | 26 julio, 2021 - Idealliance — what stocks are you on most weeks?
On my 6‑color 40" Heidelberg, the biggest make‑ready drop came after a Fogra PSD workshop where we baked in dry‑back: measure with the eXact in M1, then add a 2–3 dE00 dry‑down offset in the closed loop so your first OK matches the 15‑minute sheet. Small caveat: it only helps if your loop can bias LAB targets, not just density. @OP, do you have M1 locked and the ability to enter a fixed dry‑down bias?
Best return for me wasn’t another spec course but an X‑Rite ColorCert Advanced session on ISO 20654 — ‘build curves to SCTV, not TVI’ for spot channels. With your eXact on the 6‑color 40" Heidelberg, switching to SCTV targets and re‑linearizing per stock cut pulls and tightened dE on brand colors. If you’re mostly CMYK, ROI’s smaller — do you run a lot of +1/+2 specials?
