Assuring the quality of a product is a big problem for all companies. Statistical process control is the main quantitative tool used in TQM. For monitoring the process some statistical process control techniques are used. The most important tool for monitoring the process is quality control chart. Control charts are used in analysis of process changes. Main subject of this study is to construct a quality control chart for offset printing machine in a printery company. Because of the fact that there are some problems in the machines with respect to the color shifting and paper thickness in the output, this study aims at analyzing the production process for decreasing the shifts and the variation in paper thickness. An offset printing machine in the company is selected for constructing the quality control chart. This work focuses on 54*72 Heidelberg offset printing (2 Colors) brand printing machine and paper thickness in Advertising and Printing Company.
