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

平常見到的畫冊(cè)尺寸為16開，即210×285mm，原因是這種尺寸節(jié)約紙張，標(biāo)準(zhǔn)大度紙張為889×1194mm，一張大度紙張剛好可以印16個(gè)頁面，因此叫大度16開。一般書籍尺寸略有不同，書籍采用標(biāo)準(zhǔn)正度紙張印刷，正度尺寸為787×1092mm，16開算下來尺寸為185×260mm，所以我們?cè)趫D書館看到的小說散文類書籍絕大部分為這個(gè)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.

宣傳冊(cè)是我們生活中非常常見的一種畫冊(cè)，不少的公司會(huì)把自己的產(chǎn)品印成一本畫冊(cè)，企業(yè)畫冊(cè)印刷，然后去向路人發(fā)放，如何來通過畫冊(cè)挺高選擇的效果呢？畫冊(cè)的色彩是不可缺少的一方面，下面濟(jì)南畫冊(cè)印刷廠家華正印刷帶大家來了解一下如何提高戶廁的色相飽和度：

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，人們根據(jù)色相來稱呼顏色如紅色、黃色、綠色等。色相由物體表面反射到人眼視神經(jīng)的色光來確定。對(duì)于單色光可以用其光的波長確定。若是混合光組成的色彩，則以組成混合光各種波長光量的比例來確定色相。例如：在日光下，畫冊(cè)印刷，印刷品表面反射波長為500～550nm的色光，而相對(duì)吸收其它波長的色光，該印刷品在視覺上的感覺便是綠色。

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線的形狀來表示，濟(jì)南畫冊(cè)印刷，曲線A表示物體的色相為綠色，曲線B表示物體的色相為綠藍(lán)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

在光度學(xué)上把顏色的亮度描述成光的數(shù)值（即光的能量）。可以用光度計(jì)測(cè)量。一般認(rèn)為，畫冊(cè)印刷報(bào)價(jià)，彩色物體表面的反射率高，它們亮度就大，A、B兩種顏色的色相是相同的，但A顏色的亮度大于B，因而在視覺上A、B兩種顏色是有差異的。

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.

飽和度

saturation

飽和度（也叫彩度）指顏色的純潔性，可見的各種單色光是飽和的顏色。當(dāng)光譜色摻入的白光成分愈多時(shí)，就愈不飽和。

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.

物體顏色的飽和度取決于該物體表面反射光譜輻射的選擇性，物體對(duì)光譜某一較窄波段的反射率高，而對(duì)其它波長的反射率很低或沒有反射，這一顏色的飽和度就高。

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.
