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过程中的一项重要工作，这项工作的做法直接关系到产品宣传册的印刷质量，因为色彩鲜艳，亮度好，呼市印刷厂电话色调准确是彩色印刷的基本要求，要实现这一要求，先要准确分配印刷油墨，因此，操作人员应掌握色彩知识和调墨工艺。

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，掌握三原色变化规律，实现准确的油墨配置，任何颜色都可以用三原色的不同比例混合，油墨的色调变化正式使用，例如，三原色油墨可以在等量混合后变成黑色（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.

印刷产品是靠视觉上的感觉来仲裁的艺术产品，但是画册印刷产品质量的好坏直接是取决于很多因素的，比如说性能优良的印刷纸张，它可以很好地将印刷油墨转移到画册产品上，使其图画文字变得更加清晰，从而获得令人更加满意的效果。

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.

但是由于印刷纸张等材料还有印刷工艺是受很多因素制约着的，所以大多数彩色印刷产品不可以得到忠实再现性，而仅仅只可以使印刷图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，印刷纸张特性对画册印刷产品光泽度的影响，在印刷画册产品过程当中，印刷厂家油墨墨膜的转移使之印刷纸面变得平滑，可见印刷产品印刷油墨墨膜对光镜面的反射起到重要的作用，而印刷油墨墨膜表面又和印刷纸张的特性紧密相连。

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响，印刷油墨墨膜是对印刷产品光泽度影响的主要原因之一，在印刷纸张较大限度的吸收印刷油墨之后，剩下的连洁料就会被保存到印刷油墨墨膜当中，它可以很快的提高印刷产品的光泽度，印刷油墨墨膜的厚度越厚，连洁料剩下的就越多，就会越有利于使画册印刷产品的光泽度越好越明显。

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.
