It is generally known that the process of color offset printing is complex and the production of an offset printed product normally goes through a dozen or so steps before reaching completion. Among them involve the different assessment methods or requirements of the company and employees toward the printed product under different environments at different timing. Hence during this process, certain rules and relevant quality controls are required to be established.      

The purpose of color management is to let different equipment be able to maintain consistency in the presentation effect of colors, so as to improve on the fine variance between the original draft, sample and product. During the offset printing process, the use of random sampling of offset printing products is able to discover issues in data deviation and find out the root cause promptly to rectify the issue, thereby ensuring the quality of the offset printing product.  

In order to produce high quality color offset printing products, quality management of the production process must be reinforced. Quality management relies mainly on the objective assessment standards applied to the product, establishing a set of stringent data rules that leverage on various instruments for objective testing and assessment of the color quality and other quality aspects of the offset printing product.
