济南宣传单页印刷公司为您讲解：
Many enterprises or products will be introduced to the outside world with a leaflet, in which there will be various colorful text or graphics to attract attention. So, what are the precautions for the color sequence of leaflet printing? Next, Jinan leaflet printing company will explain to you:
1、根据原稿的内容和特点确定宣传单页印刷色序。一般以暖色调为主的宣传单页印刷品，如人物画等先印红、后印青；
1. Determine the color order of leaflet printing according to the content and characteristics of the original. Generally, one-page printed materials with warm colors, such as figure paintings, are printed first in red and then in blue;
2、以文字和黑色实地为主的宣传单页印刷品，宣传单页印刷色序一般采用青、品红、黄、黑。但不能在黄色实地上宣传单页印刷黑色文字及图案，因为黄色油墨粘度小，黑色油墨粘度大，容易产生逆套印现象，造成黑色油墨印不上或印不实；
2. The color sequence of leaflets printed with text and black is generally cyan, magenta, yellow and black. However, it is not allowed to print black text and patterns on a single page on the yellow field, because the yellow ink viscosity is small, and the black ink viscosity is large, which is easy to produce reverse overprinting, resulting in the black ink can not be printed or not printed;
3、宣传单页印刷根据网店覆盖面积的大小确定宣传单页印刷色序，一般情况下，网点覆盖面积小的先印，网点覆盖面积大的后印；
3. The color order of leaflet printing is determined according to the size of the coverage area of the online store. Generally, those with small coverage area will be printed first, and those with large coverage area will be printed later;
4、根据平网和实地排列宣传单页印刷色序。宣传单页印刷品有平网和实地时，为获得好的宣传单页印刷质量，避免纸张交接过程中产生蹭脏问题，使实地平服、墨色鲜艳厚实，一般先印平网图文，后印实；
4. Arrange the color order of leaflet printing according to the flat screen and on the spot. When the printed materials of leaflets have flat screen and field, in order to obtain good printing quality of leaflets, avoid the problem of rubbing dirt in the process of paper handover, and make the field plain, bright and thick, the flat screen pictures and texts are generally printed first, and then printed;
5、根据机型列宣传单页印刷色序。单色机和多色机由于叠印状态不同（前者为湿叠干，后者为湿叠湿），宣传单页印刷色序的安排也有所不同，一般情况下，单色机和双色机的宣传单页印刷色序以明暗色相互交替为宜，四色宣传单页印刷机一般先印暗色，后印亮色
5. The color order of the leaflet is printed according to the model. Due to the different overprinting status of monochrome machine and multi-color machine (the former is wet and dry, and the latter is wet and wet), the arrangement of color sequence of leaflet printing is also different. Generally, the color sequence of leaflet printing of monochrome machine and bicolor machine should be alternated between light and dark colors. The four-color leaflet printing machine generally prints dark colors first and then bright colors
6、根据纸张的性质排列色序。各种纸张的平沉滑度、百度、纤维松散度、表面强度和吸墨性不同，对于吸墨性好的纸张，先印暗色，后印亮色；对于吸墨性差的纸张，先印亮色，后印暗色，因为像黄墨这样的亮色油墨可以遮盖掉毛、掉粉等纸张缺陷。在炎热的夏天，当用报纸印单色时，如果遇到纸张含水量不均匀，褶皱不平整，纸张表面强度差而引起纸张掉毛和掉粉等情况，可采用先印一道水的措施；
6. Arrange the color order according to the nature of the paper. The smoothness, density, fiber dispersion, surface strength and ink absorption of all kinds of paper are different. For the paper with good ink absorption, the dark color is printed first, and then the bright color is printed; For the paper with poor ink absorption, the bright color should be printed first, and then the dark color, because the bright color ink such as yellow ink can cover the paper defects such as hair loss and powder loss. In the hot summer, when printing monochrome with newspaper, if the water content of the paper is uneven, the wrinkles are uneven, and the surface strength of the paper is poor, which causes the paper to lose wool and powder, the measure of printing a layer of water can be adopted first;
7、根据三原色油墨的明度排列宣传单页印刷色序。油墨的明度反映在油墨的分光广度曲线上，反色率越高，油墨的明度越高。三原色油墨明度的排列顺序为黄、青、品红、黑。
7. Arrange the color order of leaflet printing according to the brightness of the tri-color ink. The brightness of the ink is reflected in the spectral breadth curve of the ink. The higher the color reversal, the higher the brightness of the ink. The order of brightness of the three primary inks is yellow, cyan, magenta and black.
8、根据油墨的干燥性排列宣传单页印刷色序。时间证明，黄墨比品红的干燥速度快近两倍，品红墨比青墨快一倍。黑墨固着慢。干性慢的油墨应先印，干燥快的油墨后印。单色机叠印为防玻璃化，一般后印黄色以加速结膜干燥；
8. Arrange the color sequence of leaflet printing according to the dryness of the ink. Time has proved that the drying speed of yellow ink is nearly twice faster than that of magenta, and that of magenta ink is twice faster than that of green ink. Black ink is fixed and slow. The slow drying ink should be printed first, and the fast drying ink should be printed later. Monochrome machine overprinting is to prevent vitrification, and yellow is generally printed to speed up the drying of conjunctiva;
After the leaflet is designed, the printing color sequence should follow the technological principles to produce a beautiful effect. You can come to our website at any time if you have relevant printing requirements https://www.sdhzyw.com Leave a message or contact us directly!
