In this case, spot color appears to make up for this deficiency. Spot color is printed directly by chromatography, which distributes the required ink color according to the proportion of chromatography. The color does not need point density to control, so the whole color is solid and looks more textured. Spot colors are gold and silver, but there are actually thousands of spot colors in the Pantone spectrum. If the required color is not on the chromatogram, you can also adjust the required color according to the experience of the color master to find the proportion of ink. The special color printing of four-color printing pictures in Shandong printing factory generally plays an important role in books and periodicals, but it is mostly used for packaging, which makes the printing color more textured and visual impact stronger, such as cigarette packaging.

台历打印设计要考虑到实际尺寸与日历宽度长度的比例;设应考虑实际尺寸的月历与长宽比:有的月历是方形的，有纵向长条的，也有横向长方形的，设应考虑实际尺寸与长宽比的关系，设计后尽量美观。

The proportion between the actual size and the width and length of the calendar shall be considered in the design of desk calendar printing; The design shall consider the actual size of the monthly calendar and the length width ratio: some monthly calendars are square, with longitudinal strips and transverse rectangles. The design shall consider the relationship between the actual size and the length width ratio, and try to be beautiful after design.

影响飞墨的要素

Factors affecting flying ink

(1)油墨黏渡过大，油墨在墨辊出口处被拉长，易产生飞墨，同时还会构成传墨不匀，使纸张拔毛脱粉，济南台历印刷纸张从橡皮布上剥离艰难，易花版、掉版等;黏渡过小，墨层团结不佳，易产生飞墨，同时易使油墨乳化，起浮脏、糊版、网点扩展，影响印刷产质量量。

(1) The ink viscosity is too large, and the ink is elongated at the outlet of the ink roller, which is easy to produce flying ink. At the same time, it will also form uneven ink transmission, which will make the paper hair and powder removal. It is difficult to peel the printing paper of Jinan desk calendar from the blanket, and it is easy to flower and drop the plate, etc; The viscosity is too small and the ink layer is not united well, which is easy to produce flying ink. At the same time, it is easy to emulsify the ink, float dirty, paste plate and dot expansion, which affect the printing output and quality.

(2)墨辊上墨层愈厚，飞墨愈大。打样在铜版纸上，墨层厚度在1.2μm时，版上油墨只需抵达2.8g/m2就行;但用胶版纸印刷，版上油墨少要抵达4g/m2。遇到纸张性能对油墨黏附力不好的状况，易构成墨辊堆墨，从而产生飞墨。

(2) The thicker the ink layer on the ink roller, the larger the flying ink. Proofing on coated paper, the thickness of ink layer is 1.2 μ M, the ink on the plate only needs to reach 2.8g/m2; However, when printing with offset paper, the ink on the plate should reach 4G / m2. In case of poor adhesion of paper performance to ink, it is easy to form an ink roller to pile ink, resulting in flying ink.

(3) 墨辊外表凹凸不平及外表干结龟裂时，局部油墨层加厚，墨雾量加大，易产生飞墨。

(3) When the surface of the ink roller is uneven and the surface is dry and cracked, the local ink layer is thickened and the ink mist is increased, which is easy to produce flying ink.

(4) 印刷速度增加，飞墨加大。

(4) The printing speed increases and the flying ink increases.

(5) 空气相对湿度小，飞墨产生;湿度加大时，电荷减少，飞墨质变小。

(5) The relative humidity of air is small, and flying ink is produced; When the humidity increases, the charge decreases and the quality of flying ink decreases.
