2, printing plate inking performance
The inking performance of the plate, especially the inking performance of the plate after a high time of wear. Although the current plate technology has made progress, reducing the problem of printing color difference to a certain extent, the printing plate after a prolonged time of wear will reduce its inking performance, resulting in shallow imprint, ink layer saturation and other problems. If you encounter such problems, merely increasing the printing pressure can not fundamentally solve the problem. Instead, it will cause additional wear of the plate and increase the printing color difference, and may reduce the overall compressive strength of the packaging product.
3. Control of printing pressure and speed
The uniformity of printing speed and printing pressure will make the printing color produce different effects. On the one hand, when the printing speed is accelerated, the amount of ink will increase, the ink layer will become thicker, and the corresponding color will be heavier; on the contrary, when the printing speed decreases, the amount of ink decreases, the ink layer becomes thinner, the imprint will become lighter, resulting in the amount of ink is difficult to reach saturation. On the other hand, if the printing pressure is overly large, the amount of ink is tiny, it will cause imprinting deficiency; if the pressure is overly tiny, the gap between the rollers increases, the amount of ink will cause the ink layer to become thicker, the color will become heavier, especially in the dot printing is easy to cause paste plate and other phenomena. Therefore, to ensure the stability of the printing effect, we must do a decent job of printing speed and printing pressure control.
4, the smoothness of corrugated board and sizing
The smoothness and sizing of paper will also cause the color difference in carton printing. Extreme smoothness of paper, ink layer plane reflection, color will appear bright, light color; on the contrary, rough paper, ink layer diffuse reflection, hue will appear heavy. The size of the paper sizing affects the adhesion of ink, and the thickness of the ink layer directly affects the size of the color difference.
The above is a brief introduction to several related factors that cause printing color difference. Of course, there are numerous factors affecting the printing effect of corrugated packaging, such as: the management of printing color samples by manufacturers, as well as the attitude of operators, inspectors and other relevant staff to their work will have a certain degree of influence on the quality of packaging products. Therefore, every production enterprise must do good job training for employees and improve the relevant system of the enterprise, so as to ensure product quality and promote the excellent development of the enterprise.
What do you know about the factors that cause the color difference of packaging printing
With the continuous improvement of consumption level, people's packaging requirements of products are more strict. As far as corrugated packaging is concerned, the printing process is an essential link in the production of corrugated packaging. In the process of printing, it is inevitable to encounter quality accidents such as printing color difference. Then what are the factors causing the printing color difference? paper box custom Xiaobian for you to make the following share.
1, printing ink stability
Stable ink quality is the key factor to control printing color difference. If the quality of ink changes, it will lead to a world of difference in printing effect. Especially at present, in order to reflect the uniqueness of the brand and increase the anti-counterfeiting, some customers will use spot color ink, and the deployment of spot color ink must be accurate to ensure the stable color of ink, which requires the technical requirements of on-site ink mixing personnel. In addition, printing ink will have the problem of increasing volatilization stations, which will also have a certain impact on the printing color difference, therefore the field staff in addition to control the contrast when adjusting ink, but also pay attention to the shift of ink viscosity in the process of printing.
