印刷中影響中性灰平衡的因素

來源:http://www.lyjinshayun.com/   發布時間:2023-03-20
中性灰平衡由于能夠保證印刷過程中正確復制原稿的樣式,所以非常重要。為保證印刷過程中的中性灰平衡,需要了解中性灰平衡的影響因素。下面山東印刷包裝廠家為您分析:
Neutral gray balance is very important because it ensures the correct reproduction of the original style during the printing process. To ensure neutral gray balance in the printing process, it is necessary to understand the influencing factors of neutral gray balance. The following is an analysis by Shandong printing and packaging manufacturers:
這先要搞清楚色彩的變化規律,三原色油墨按一定比例能混合近似黑色,再加上不同比例的沖淡劑,那么,得到不同顏色的中性灰。三原色以不同比例混合能得到不同色相的間色或復色,色相偏于比例大的色相。
First, it is necessary to understand the law of color change. Three primary inks can be mixed to approximate black in a certain proportion, and then different proportions of diluents are added to obtain neutral grays of different colors. Mixing three primary colors in different proportions can result in different shades of intermediate or multiple colors, which tend to be larger in proportion.
紙張的性能與中性灰平衡關系,印刷企業的產品質量受原材料紙張影響較大,理想的紙張白度為100%的反射率,全反射380~700nm的光線。在制版、印刷過程中就要考慮“因紙而異”,采用合適的工藝內容去適應所使用的紙張,尤其是在網點的粗細、套色的多少、版面反差大小等方面。
The performance of paper is related to the neutral gray balance. The product quality of printing enterprises is greatly affected by the raw material paper. The ideal paper whiteness is 100% reflectance, with a total reflection of 380 to 700 nm of light. In the process of plate making and printing, it is necessary to consider "paper specific" and adopt appropriate technological content to adapt to the paper used, especially in terms of the thickness of the dot, the amount of chromatic register, and the size of the page contrast.

印刷色序與中性灰關系,考慮到了讓透明度低的油墨放在色印刷,然后再印透明度高的油墨,這種色序排列是按油墨的透明度大小來排列的。同時還考慮到油墨粘度,可以避免印刷品背面粘臟現象;淺顏色放在前面印,清洗墨輥就很容易;也便于四色套印準確性。
The relationship between printing color order and neutral gray is first considered to allow low transparency inks to be printed on the first color, followed by high transparency inks. This color order arrangement is arranged according to the transparency of the inks. At the same time, ink viscosity is also considered, which can avoid the phenomenon of sticky dirt on the back of the printed matter; Light colors are printed on the front, making it easy to clean the ink roller; It also facilitates the accuracy of four-color overprinting.
多色膠印機是濕疊濕,印刷油墨在沒有氧化結膜干燥的情況下,另外一種顏色油墨又疊印上去了。不同的色序排列對中性灰平衡是有較大影響的,不同的色序會直接影響到印刷出來產品質量和色彩的色調.
Multicolor offset presses are wet stacked, and the printing ink is overprinted with another color ink without drying the oxidation film. Different color order arrangements have a significant impact on the neutral gray balance, and different color orders directly affect the quality of printed products and the hue of colors
生產實際中要綜合分析,把印刷工藝中涉及的一些可變因素考慮得再多一點,在色序排列上要根據不同類型的原稿、客戶的要求印刷出來的效果進行安排色序,才能達到印刷品的再現復制原稿的要求。更多相關印刷事項就來我們網站http://www.lyjinshayun.com咨詢了解吧!
In production practice, it is necessary to comprehensively analyze and consider some variable factors involved in the printing process a little more. In terms of color sequence arrangement, it is necessary to arrange the color sequence according to different types of originals and the effects of printing required by customers, in order to achieve the requirements of reproducing and reproducing the originals of printed products.
