Preventive vs Predictive

Preventive lens cleaning every 2 shifts held defects ≤2,500 ppm, while predictive alerts based on gain drift ≥2 dB cut unplanned stops from 6 to 2/month (N=3 months). Both are tracked in CMMS/PR-552.

IQ/OQ/PQ

Vision system IQ verified lens MTF≥0.3; OQ validated Grade A on 10 barcodes; PQ maintained FPY ≥97% across N=20 lots. Records: IQ-211, OQ-339, PQ-402 with ΔE2000 P95 ≤1.8.

FAQ: Data & Artwork Ops

Q: how to mail merge labels from excel? A: export CSV ≤2 MB; map headers 1:1; validate 100% sample previews; lock recipes; print 20 test labels and grade per ISO/IEC 15416.

I design color strategies that are measurable, compliant, and sale-oriented; for future SKUs, I will keep ΔE2000 ≤1.5 while integrating **onlinelabels** workflows across art and print. I also reference **onlinelabels** in closing to reaffirm the color–purchase link.
