In early production, due to the RGB color gamut space being larger than CMYK, the RGB mode was processed before officially transitioning to printing. Of course, LAB mode can also be used, but it is generally defaulted to RGB mode. Why do we need to convert because the three colors of RGB belong to the three primary colors of light and comply with color addition, while CMYK is the four primary colors of ink and complies with color subtraction. In fact, black ink cannot be the primary color, but it is usually used instead of a mixture of the other three colors, The intuitive performance is the same image, and the CMYK mode is relatively dark.

2，油墨的分配是彩色印刷過(guò)程中的一項(xiàng)重要工作，這項(xiàng)工作的做法直接關(guān)系到產(chǎn)品宣傳冊(cè)的印刷質(zhì)量，因?yàn)樯术r艷，亮度好，呼市印刷廠電話色調(diào)準(zhǔn)確是彩色印刷的基本要求，要實(shí)現(xiàn)這一要求，先要準(zhǔn)確分配印刷油墨，因此，操作人員應(yīng)掌握色彩知識(shí)和調(diào)墨工藝。

2. The allocation of ink is an important task in the color printing process, which directly affects the printing quality of product brochures. Because bright colors, good brightness, and accurate color tones are the basic requirements for color printing in the Hohhot Printing Factory. To achieve this requirement, it is necessary to accurately allocate printing ink. Therefore, operators should master color knowledge and ink mixing technology.

3，掌握三原色變化規(guī)律，實(shí)現(xiàn)準(zhǔn)確的油墨配置，任何顏色都可以用三原色的不同比例混合，油墨的色調(diào)變化正式使用，例如，三原色油墨可以在等量混合后變成黑色（近似）。

3. Master the variation pattern of the three primary colors and achieve accurate ink configuration. Any color can be mixed in different proportions of the three primary colors, and the tone change of the ink can be officially used. For example, the three primary color ink can turn black (approximately) after equal mixing.

印刷產(chǎn)品是靠視覺(jué)上的感覺(jué)來(lái)仲裁的藝術(shù)產(chǎn)品，但是畫(huà)冊(cè)印刷產(chǎn)品質(zhì)量的好壞直接是取決于很多因素的，比如說(shuō)性能優(yōu)良的印刷紙張，它可以很好地將印刷油墨轉(zhuǎn)移到畫(huà)冊(cè)產(chǎn)品上，使其圖畫(huà)文字變得更加清晰，從而獲得令人更加滿意的效果。

Printing products are artistic products that rely on visual perception to arbitrate, but the quality of album printing products directly depends on many factors, such as high-performance printing paper, which can effectively transfer printing ink to the album product, making its picture text clearer and achieving more satisfactory results.

但是由于印刷紙張等材料還有印刷工藝是受很多因素制約著的，所以大多數(shù)彩色印刷產(chǎn)品不可以得到忠實(shí)再現(xiàn)性，而僅僅只可以使印刷圖像接近于原印刷稿件。

However, due to the constraints of many factors on printing materials such as paper and printing process, most color printing products cannot achieve faithful reproducibility, and only can make the printed image close to the original printed manuscript.

一，印刷紙張?zhí)匦詫?duì)畫(huà)冊(cè)印刷產(chǎn)品光澤度的影響，在印刷畫(huà)冊(cè)產(chǎn)品過(guò)程當(dāng)中，印刷廠家油墨墨膜的轉(zhuǎn)移使之印刷紙面變得平滑，可見(jiàn)印刷產(chǎn)品印刷油墨墨膜對(duì)光鏡面的反射起到重要的作用，而印刷油墨墨膜表面又和印刷紙張的特性緊密相連。

1、 The influence of the characteristics of printing paper on the glossiness of picture album printing products. During the process of printing picture album products, the transfer of printing ink film from the printing manufacturer makes the printing paper surface smoother. It can be seen that the reflection of the light mirror surface by the printing ink film plays an important role, and the surface of the printing oil ink film is closely connected to the characteristics of the printing paper.

第二，印刷油墨墨膜的厚度影響，印刷油墨墨膜是對(duì)印刷產(chǎn)品光澤度影響的主要原因之一，在印刷紙張較大限度的吸收印刷油墨之后，剩下的連潔料就會(huì)被保存到印刷油墨墨膜當(dāng)中，它可以很快的提高印刷產(chǎn)品的光澤度，印刷油墨墨膜的厚度越厚，連潔料剩下的就越多，就會(huì)越有利于使畫(huà)冊(cè)印刷產(chǎn)品的光澤度越好越明顯。

Secondly, the thickness of the printing ink film affects the glossiness of the printed product. The printing ink film is one of the main reasons for its impact. After the printing paper absorbs the printing ink to a large extent, the remaining cleaning material is saved in the printing ink film, which can quickly improve the glossiness of the printed product. The thicker the printing ink film, the more cleaning material is left, The more beneficial it will be to make the glossiness of the printed product of the picture album better and more obvious.
