Quality is the lifeline of the printing industry. Most printers would never think of eliminating the quality control function from their production processes. Without quality control, the number of defective products that must be reworked, scrapped or returned would dramatically increase. Almost all printing organizations monitor the quality of the product they deliver to uphold their reputations, ensure satisfied customers and generate repeat business. Quality control is more and more, assuming an importance in the printing industry Quality control can be said to be the overall system of activities whose purpose is to provide a quality product or service that meets the needs of the users, and also the use of such a system.

The quality of reproduction of color images in offset printing is dependent on a number of parameters in a chain of steps and in the end it is the amount and the distribution of ink deposited on the substrate that create the sensation and thus the perceived colors.
