60°鏡面光澤不大于5光澤單位。
60 ° mirror gloss shall not exceed 5 gloss units.
光澤是物體的外觀光學特性。表面平滑材料收到可見光的照射都會產(chǎn)生有方向性的向另一方向的反射現(xiàn)象,這稱為鏡面反射,其結(jié)果使材料表面帶有光澤即為鏡面光澤,其反射能力的大小稱為鏡面光澤度。
Gloss is the optical characteristic of an object's appearance. Smooth surface materials that receive visible light will produce directional reflection in the other direction, which is called specular reflection. The result is that the material surface has a luster, which is called specular luster. The size of its reflection ability is called specular glossiness.
涂層鏡面光澤度的大小是通過測量試樣表面的反射光通量與入射光通量的比值來確定。通常采用60°入射角測量。優(yōu)質(zhì)的無光澤表面設置為0??墒褂霉鉂啥扔媮頊y量產(chǎn)品的光澤度。
The size of the specular glossiness of the coating is determined by measuring the ratio of the reflected luminous flux to the incident luminous flux on the sample surface. Usually measured at a 60 ° incidence angle. Set the high-quality matte surface to 0. A glossmeter can be used to measure the glossiness of the product.
色差不大于3L*a*b*單位。
The color difference shall not exceed 3L * a * b * units.
色彩的表示方式,也就是色彩模式有多種,有RGB模式、XYZ模式、L*a*b*模式等。管理這些模式的是國際照明委員會。這些模式之間都是可以相互換算的。至于建立模式的原理和換算關系沒有必要細究,那是專家教授的事情。
There are various ways to represent colors, including RGB mode, XYZ mode, L * a * b * mode, etc. The International Commission on Illumination governs these models. These modes can be converted to each other. As for the principles and conversion relationships of establishing patterns, there is no need to delve into them, it is the responsibility of experts and professors.
RGB色彩模式是工業(yè)界的一種顏色標準,是通過對紅(R)、綠(G)、藍(B)三個顏色通道的變化以及它們相互之間的疊加來得到各式各樣的顏色的,RGB即是代表紅、綠、藍三個通道的顏色,這個標準幾乎包括了人類視力所能感知的所有顏色,是目前運用廣的顏色系統(tǒng)之一。而與我們電腦相關的地方,就是目前的顯示器大都是采用了RGB顏色標準,RGB是從顏色發(fā)光的原理來設計定的,通俗點說它的顏色混合方式就好象有紅、綠、藍三盞燈,當它們的光相互疊合的時候,色彩相混,而亮度卻等于兩者亮度之總和,越混合亮度越高。
The RGB color mode is a color standard in the industry, which obtains a variety of colors through changes in the red (R), green (G), and blue (B) color channels and their superposition. RGB represents the colors of the red, green, and blue channels. This standard includes almost all colors that human vision can perceive, and is currently one of the most widely used color systems. And what is related to our computer is that most of the current monitors use the RGB color standard. RGB is designed based on the principle of color luminescence. In simple terms, its color mixing method is like having three lights: red, green, and blue. When their lights overlap, the colors mix, and the brightness is equal to the total brightness of the two. The more mixed, the higher the brightness.
XYZ模式只是在RGB色彩模式的基礎上,用數(shù)學方法表示的一種模式。X、Y、Z稱為三刺激值。其中X與Z只代表色度,無亮度。光亮度只與三刺激值Y成正比。這一點正與可見光亮度對比公式有關。
The XYZ mode is only a mathematical representation based on the RGB color mode. X. Y and Z are called tristimulus values. Among them, X and Z only represent chromaticity and have no brightness. The brightness is only proportional to the tristimulus value Y. This is directly related to the formula for comparing the brightness of visible light.
偽裝網(wǎng)
L*a*b*模式是XYZ色彩模式的改進型。它的L*(明亮度)、a*(綠色到紅色)和b*(藍色到黃色)代表許多的值。與XYZ比較,L*a*b*色彩模式更適合于人眼感覺的色彩。利用這個模式,可以單獨修正色彩的亮度L*、灰階和飽和度a*b*。
The L * a * b * mode is an improved version of the XYZ color mode. Its L * (brightness), a * (green to red), and b * (blue to yellow) represent many values. Compared with XYZ, the L * a * b * color mode is more suitable for colors perceived by the human eye. By using this mode, the brightness L *, grayscale, and saturation a * b * of colors can be individually corrected.
在偽裝網(wǎng)的研發(fā)和生產(chǎn)中,一般會應用到L*a*b*模式和XYZ模式,在模式中的數(shù)值可以通過樣品檢測獲得。如果對照色使用了GJB1082-91《偽裝網(wǎng)用顏色》的標準色,可以通過標準查到相應數(shù)值。
In the development and production of camouflage nets, the L * a * b * mode and XYZ mode are generally applied, and the values in the mode can be obtained through sample testing. If the reference color uses the standard color of GJB1082-91 "Colors for Camouflage Nets", the corresponding values can be found through the standard.
色差⊿E*ab計算:
Calculation of color difference Δ E * ab:
⊿E*ab=﹝﹙⊿L*﹚2+﹙⊿a*﹚2+﹙⊿b*﹚2﹞1/2
Delta E * ab=(Delta L *) 2+(Delta a *) 2+(Delta b *) 2) 1/2
式中:⊿L*、⊿a*、⊿b*——偽裝網(wǎng)樣品色與其對應標準坐標L*、a*、b*之差。
In the formula: Δ L *, Δ a *, Δ b * - the difference between the camouflage mesh color and its corresponding standard coordinates L *, a *, b *.
⊿E*ab小于等于3,即符合標準要求。
If Δ E * ab is less than or equal to 3, it meets the standard requirements.
第三,可見光亮度對比不大于0.1。
Thirdly, the contrast of visible light brightness should not exceed 0.1.
可見光亮度對比KV計算:KV=|Ys-Yr|/Yr
Calculation of visible light brightness contrast KV: KV=| Ys Yr |/Yr
式中:Ys——樣品色在XYZ色度系統(tǒng)中的刺激值Y;Yr——標準色在XYZ色度系統(tǒng)中的刺激值Y。
In the formula: Ys - stimulus value Y of the sample color in the XYZ chromaticity system; Yr - The stimulus value Y of the standard color in the XYZ chromaticity system.
KV小于等于0.1,即符合標準要求。
If KV is less than or equal to 0.1, it meets the standard requirements.
