不少的企业都开始讲自己的产品Betway login在彩色的画册上，然后向路人发放，其实仔细看看，基本每个公司Betway login的尺寸都是一样的，那么画册的Betway login尺寸有什么样的讲究呢？济南Betway login带大家来了解一下吧：
Many enterprises begin to say that their products are printed on color picture albums and then distributed to passers-by. In fact, if you take a closer look, the printing size of each company is basically the same, so what kind of attention should be paid to the printing size of picture albums? Jinan printing belt, let's have a look at it
Usually, the size of picture album is 16 open, that is 210 × 285mm. The reason is that this size saves paper. The national standard large paper is 889 × 1194 mm. A large paper can print 16 pages, so it is called large size 16 open. Generally, the size of books is slightly different. Books are printed on national standard positive paper. The positive size is 787 × 1092mm, and the size calculated by 16 is 185 × 260mm. Therefore, most of the novels and prose books we see in the library are of this size.
宣传册是我们生活中非常常见的一种画册，不少的公司会把自己的产品印成一本画册，企业画册Betway login，然后去向路人发放，如何来通过画册挺高选择的效果呢？画册的色彩是不可缺少的一方面，下面济南画册Betway login
Brochures are very common picture books in our life. Many companies will print their products into a picture album, and then print them to passers-by. How can we achieve a high selection effect through the album? The color of the album is an indispensable aspect. Let's take a look at how to improve the hue saturation of household toilets
色相是色彩基本的特征，人们根据色相来称呼颜色如红色、黄色、绿色等。色相由物体表面反射到人眼视神经的色光来确定。对于单色光可以用其光的波长确定。若是混合光组成的色彩，则以组成混合光各种波长光量的比例来确定色相。例如：在日光下，画册Betway login多少钱，Betway login品表面反射波长为500～550nm的色光，而相对吸收其它波长的色光，该Betway login品在视觉上的感觉便是绿色。
Hue is the basic feature of color. People call colors according to hue, such as red, yellow, green, etc. The hue is determined by the color light reflected from the surface of the object to the human optic nerve. The monochromatic light can be determined by its wavelength. If the color is composed of mixed light, the hue is determined by the proportion of light quantity of various wavelengths. For example, how much does an album cost to print in sunlight? The color light reflected on the surface of the printed matter is 500-550nm, while the color light of other wavelengths is absorbed, the visual feeling of the printed matter is green.
The color phase can be represented by the shape of the spectral reflectance curve. Printed in Jinan album, curve a indicates that the color phase of the object is green, and curve B indicates that the color phase of the object is green blue.
In photometry, the brightness of a color is described as the value of light (i.e. the energy of light). It can be measured with a photometer. It is generally believed that when a picture album is printed, the surface reflectance of color objects is high, and their brightness is large. The hues of a and B are the same, but the brightness of color a is greater than that of B. therefore, there are differences between a and B in terms of vision.
Saturation (also known as chromaticity) refers to the purity of color, visible monochromatic light is saturated color. The more white light is added into the spectrum, the more unsaturated it will be.
The saturation of an object's color depends on the selectivity of the spectral radiation reflected by the surface of the object. If the reflectance of the object to a narrow band of the spectrum is high, but the reflectivity of other wavelengths is very low or no reflection, the saturation of the color is high.
