柔印中影响灰平衡的两大方面因素(国外英文资料) Core tip: gray balance is used to judge whether the balance of the color or color offset printing, occupies an important position in the printed copy, as long as to be able to recognize these effects of flexo printing gray balance factor, and the various links in the actual production of the reasonable control, guarantee the accuracy of gray balance reproduction. It can not only make prints are stable and accurate color reproduction, but also can improve the quality of printing and printing enterprise production efficiency. Gray balance is used to judge whether the balance of the color or color offset printing, occupies an important position in printing, the printing process is the ten on the basis of quality control, but also the process of the core data control. Similarly, it is also a problem that deserves special attention in color flexo printing. In flexographic printing, there are many factors that affect the gray balance. It can be said that almost every link in the process of color reproduction and printing will lead to changes in the gray balance. It can be analyzed and explained in two aspects. First, color separation process conditions The gray balance control runs through the flexible plate making and printing process. Color separation is the key to color reproduction. Each set of colors of ink and a corresponding separations of gray balance, indiscriminate change ink brand and color, the color balance will destroy the entire image and gray balance. For color separation process, the main factor to consider is the curve, so there will be different color separation and plate making results. Ink characteristics Different manufacturers of ink gray balance curves of different needs, basic characteristics of the ink plate before (such as hue, saturation and brightness) and physicochemical properties (such as ink ink drying speed and gloss) were measured to find the right balance between gray curve, in order to seihan of these factors u
