Offset printing is the main way of Jinan album printing. Most of the mainstream printing machines used are Heidelberg, Roland, Xiaosen, Mitsubishi, etc. with high intelligence, as long as the operators are familiar with the printing machine in the operation process, the setting of printing process parameters, and basically understand the internal structure of the printing machine, they can print a good product. Generally speaking, it mainly controls ink balance, printing pressure and printing speed.

　　印刷压力太小，油墨不易转移，油墨轻、弱;印刷压力过大，油墨对非图文部分的膨胀，使网点增大严重，图像失真，还容易使印版和橡皮布产生耐印性。因此，必须正确调整机械压力。不同的定量纸张需要不同的印刷压力，只有适当的印刷压力，才能保证油墨均匀、厚度相同。

　　The printing pressure is too small, the ink is not easy to transfer, and the ink is light and weak; the printing pressure is too large, and the ink expands the non graphic part, so that the dot dot increases seriously, the image is distorted, and it is easy to make the printing plate and the blanket produce the printing resistance. Therefore, the mechanical pressure must be adjusted correctly. Different quantitative paper needs different printing pressure. Only the appropriate printing pressure can ensure the ink is uniform and the thickness is the same.

　　印刷速度过快，容易造成脱毛、脱毛等现象。应考虑承印物的性能、承印物的尺寸、油墨的粘度等综合因素。印刷版式、厚度、基材表面强度低，印刷速度稍慢;油墨的粘度越大，印刷速度越慢。印刷速度决定了要实现文字的完整复制和的生产效率。

　　Printing speed is too fast, easy to cause depilation, depilation and other phenomena. The comprehensive factors such as the performance of substrate, the size of substrate and the viscosity of ink should be considered. Printing format, thickness, substrate surface strength is low, printing speed is slightly slow; the higher the viscosity of ink, the slower the printing speed. Printing speed determines to achieve the complete reproduction of text and the highest production efficiency.

　　油不朱平衡是一种相对平衡，而不是在高速设备运转过程中的平衡。应根据实际情况，掌握油墨的粘度和润版液的pH值，控制油墨和水对印版糊版不脏。

　　Ink balance is a relative balance, not an absolute balance in the operation of high-speed equipment. According to the actual situation, master the viscosity of ink and the pH value of the fountain solution, and control whether the ink and water are dirty on the plate paste.
