This research analyzed printing quality at Commercial Unit of PT G in Cikarang using DMAIC
method (N=46), that implemented six sigma in its production processes. The Define level identified color
stability as a significant factor for printing quality. The Measure level accessed DPMO and Sigma level for
color stability (ΔE) at 10,192 (σ=3.82), and stability processes (density, dot gain, and trapping) were
approximately at 413,472(σ=1.72). Analyzes for stability processes showed some observations exceeded UCL
and LCL; for capability processes showed the level of color stability <1.0 (ΔE=0.82); stability processes of dot
gain and trapping <1.0 (density = 1.08; dot gain=0.78; trapping=0.62). Factor analysis was done utilizing
fishbone diagram and FMEA. At Improve level, some suggestions were recommended to increase the six sigma
level. At Control level, the suggestions implemented were documented. The findings indicated that DPMO
decreased as much as 65.22% that implicated the increase of σ level from 3.82 to 4.19 for color stability, from
3.33 to 3.77 for density, from 0.85 to 2.15 for dot gain, and from 1.59 to 2.49 for trapping.
