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.
