Abstract
Recently, many printing companies are increasingly attempting to obtain certifications for printing. Certification is required by printing standards, and further, color management can be performed by the standardization. Authentication can also be used, and printing companies have increased efforts to standardize printing. However, printing may not stabilize the color due to various factors that can reduce and change the color. To reduce variability, it is important to make adjustments each day. The maintenance standards required by the printing press have contributed significantly to its stability. Here, the color is stable and adjustments create the illusion of good printing. To stabilize the printing press, a standard print can be created. In addition, it is possible to use color management. In this manner, by reducing the fluctuations in the printing press, efficient printing operations can be realized and printing accidents can be prevented.
