很多企業(yè)或產品對外介紹，都會配有一本宣傳單頁，里面會有各種彩色的文字或圖形去吸引眼球。那么，宣傳單頁印刷色序有哪些注意事項？下面
濟南宣傳單頁印刷公司為您講解：
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、根據原稿的內容和特點確定宣傳單頁印刷色序。一般以暖色調為主的宣傳單頁印刷品，如人物畫等先印紅、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、以文字和黑色實地為主的宣傳單頁印刷品，宣傳單頁印刷色序一般采用青、品紅、黃、黑。但不能在黃色實地上宣傳單頁印刷黑色文字及圖案，因為黃色油墨粘度小，黑色油墨粘度大，容易產生逆套印現象，造成黑色油墨印不上或印不實；
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、宣傳單頁印刷根據網店覆蓋面積的大小確定宣傳單頁印刷色序，一般情況下，網點覆蓋面積小的先印，網點覆蓋面積大的后??；
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、根據平網和實地排列宣傳單頁印刷色序。宣傳單頁印刷品有平網和實地時，為獲得好的宣傳單頁印刷質量，避免紙張交接過程中產生蹭臟問題，使實地平服、墨色鮮艷厚實，一般先印平網圖文，后印實；
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、根據機型列宣傳單頁印刷色序。單色機和多色機由于疊印狀態(tài)不同（前者為濕疊干，后者為濕疊濕），宣傳單頁印刷色序的安排也有所不同，一般情況下，單色機和雙色機的宣傳單頁印刷色序以明暗色相互交替為宜，四色宣傳單頁印刷機一般先印暗色，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、根據紙張的性質排列色序。各種紙張的平沉滑度、百度、纖維松散度、表面強度和吸墨性不同，對于吸墨性好的紙張，先印暗色，后印亮色；對于吸墨性差的紙張，先印亮色，后印暗色，因為像黃墨這樣的亮色油墨可以遮蓋掉毛、掉粉等紙張缺陷。在炎熱的夏天，當用報紙印單色時，如果遇到紙張含水量不均勻，褶皺不平整，紙張表面強度差而引起紙張掉毛和掉粉等情況，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、根據三原色油墨的明度排列宣傳單頁印刷色序。油墨的明度反映在油墨的分光廣度曲線上，反色率越高，油墨的明度越高。三原色油墨明度的排列順序為黃、青、品紅、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、根據油墨的干燥性排列宣傳單頁印刷色序。時間證明，黃墨比品紅的干燥速度快近兩倍，品紅墨比青墨快一倍。黑墨固著慢。干性慢的油墨應先印，干燥快的油墨后印。單色機疊印為防玻璃化，一般后印黃色以加速結膜干燥；
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 http://www.zhouyingzi.cn Leave a message or contact us directly!
