G7 Certification with Latex ink

    Dear all,

    I'm a very green G7 certified expert. I am currently working on a certification for a company who are using a HP 360 with latex ink. We are using Caldera 10.1 and 3M 48C Non-PVC. Ink dens 130% 12Pass. After linearization, I printed a P2P51 chart, imported it to Curve 4, C, M, Y, K, R, G, CMY & CMYK are doing pretty good, but Blue is like way off, 7.xx DeltaE. So then I ignored it and proceed my total ink limit and ICC profiling. After all, my B still couldn't meet the target and I couldn't only reach to G7 Target aim (My aim is GRACoL 2006 SCCA). And I have looked at my color gamut with Colorthink Pro, seems like the latex ink couldn't cover up my aim space.

    Does anyone has experiance with latex ink for G7 certification? Or is Latex ink couldn't ever get to Target or Colorspace complinace level?
