KOP Corp. is an offset printing company, especially in packaging printing (folding boxes).  KOP Corp. faced many defects in production.  This has an impact on increasing cost and customer dissatisfaction.  This paper discusses Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) to find root cause of problem. FMEA use to prioritized sources of problem. Moreover, FTA is used for finding out the root of the problem.  Based on Risk Priority Number (RPN), three failure modes with the largest RPN, namely defect printed, color is not up to standard and defect in the picture. By using the FTA method, analyzed the root problems of these failure modes. After creating a Fault Tree Diagram and looking for a minimum Cut Set, it can be recommended several improvements such as the socialization of a good sampling plan, the design of a training program, Quality Control Circle development, and the selection of good suppliers.
