济南画册Betway login如何提高户厕的色相饱和度

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
平常见到的画册尺寸为16开,即210×285mm,原因是这种尺寸节约纸张,国家标准大度纸张为889×1194mm,一张大度纸张刚好可以印16个页面,因此叫大度16开。一般书籍尺寸略有不同,书籍采用国家标准正度纸张Betway login,正度尺寸为787×1092mm,16开算下来尺寸为185×260mm,所以我们在图书馆看到的小说散文类书籍绝大部分为这个尺寸。
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厂家华正Betway login带大家来了解一下如何提高户厕的色相饱和度:


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.
色相可以利用分光反射率曲线的形状来表示,济南画册Betway login,曲线A表示物体的色相为绿色,曲线B表示物体的色相为绿蓝色。
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.
亮度
brightness
在光度学上把颜色的亮度描述成光的数值(即光的能量)。可以用光度计测量。一般认为,画册Betway login报价,彩色物体表面的反射率高,它们亮度就大,A、B两种颜色的色相是相同的,但A颜色的亮度大于B,因而在视觉上A、B两种颜色是有差异的。
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.
饱和度
saturation
饱和度(也叫彩度)指颜色的纯洁性,可见的各种单色光是饱和的颜色。当光谱色掺入的白光成分愈多时,就愈不饱和。
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.
物体颜色的饱和度取决于该物体表面反射光谱辐射的选择性,物体对光谱某一较窄波段的反射率高,而对其它波长的反射率很低或没有反射,这一颜色的饱和度就高。
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.
