1. Purpose of printing analysis

3

✦Installation of “ColorFlow” (Kodak) for analysis1. Color-‐‑‒matching for Japan Color Standard •Ultimate goal is adaption for Japan Color which is compatible with ISO12647

2.Color-‐‑‒matching for Direct Digital Color Proof•Create color profile for DDCP to be checked as first proof to avoid printing proof by press

3.Color-‐‑‒matching for different presses•Secondary goal is perfect alignment of presses in our factory and other partner factories

✦Advanced screening tech. for high-‐‑‒end printingStaccato screening (high-‐‑‒definition)Kodak Staccato is advanced, second-‐‑‒order FM screening technology. Staccato screening produces high-‐‑‒fidelity, continuous tone images that exhibit fine detail and an extended color gamut, creating a photographic experience free of visible printing artifacts, such as subject moire and rosettes.(Reference: http://graphics.kodak.co.jp/KodakGCG/uploadedFiles/Products/Color_̲and_̲Screening/Staccato_̲Screening/Staccato%20Brochure%20ENG.pdf)

The angle and frequency of half tone dots in conventional AM screens can cause subject moire, screening moire and unstable rosette structures. Additionally, fewer and larger minimum dot sizes in highlights and shadows in AM screens can result in loss of detail and increase in graininess.(Reference: http://graphics.kodak.co.jp/KodakGCG/uploadedFiles/Products/Color_̲and_̲Screening/Staccato_̲Screening/Staccato%20Brochure%20ENG.pdf)
