Description

This invention relates to an image forming system and a control program. In recent years, image forming equipment such as electrophotographic printers has become widely used in the color printing industry. In the field of PP (production print), which corresponds to the color printing industry, there is a need for adaptability to a wider variety of paper types compared to those used in office environments. To achieve high-quality printing on these diverse papers, there are image forming equipment that allow you to set multiple paper characteristics for the paper stored in the paper tray and perform paper processing, such as printing, according to the image forming conditions set for each item. To accommodate such diverse paper settings, there are image forming apparatuses equipped with sensors that automatically detect the characteristics of the paper used for printing (for example, Patent Documents 1 and 2). Furthermore, in recent years, a technique has been proposed to acquire multiple types of physical properties related to the paper, apply these acquired physical properties to a pre-prepared judgment table, and determine control parameters such as transfer voltage for controlling image formation conditions (for example, Patent Document 3).
