在生产实际中,多数是在电源的照射下工作,而每种光源均带有一定颜色。这就给正确判断原稿或产品颜色带来一定困难,色光下观色,色彩变化一般是相同色变浅,补色变暗,例如:
In actual production, the majority is in the work under the irradiation of power supply, and each light source is a certain color. This is to correctly judge the manuscript or product color brings certain difficulty, light color, the color change is generally the same color becomes shallow, complementary color darker, such as:
绿光下观色,绿变浅,青变浅,黄变绿黄,红变黑,白变绿.
Under the green color, green becomes shallow, light green, yellow green yellow, red, black, white, green.
红光下观色,红变浅,黄变橙, 绿变暗,青变暗,白变红。
Red light color, light red, yellow orange, dark green, green dark, white and red.
蓝光下观色,蓝变浅,青变浅,绿变暗,黄变黑,白变蓝。
Under the blue color, blue becomes shallow, becomes shallow green, dark green, black, white and blue.
黄光下观色,黄变浅,品红变红,青变绿 ,蓝变黑,白变黄。
Under the yellow color, light yellow, magenta red, blue, green, blue, black, white and yellow.
在印刷车间,一般都选择色温较高(3500~4100K),显色系数较好的日光灯作为看样光源,但要注意日光灯略偏蓝紫色。
In the printing workshop, generally choose high colour temperature (3500 ~ 4100 k), color factor good fluorescent lamp as the light source, but must pay attention to the fluorescent lamp slightly purple.
分两次看一种色时感觉不一样。这种现象叫做先后颜色对比反应。
Two feel differently when he saw a kind of color. This phenomenon is called successively color contrast reactions.
这是因为,先看的颜色使该色的色神经纤维兴奋,马上再看别的颜色,其它色神经很快兴奋引起色感,而先看色的色神经处于兴奋后的抑制状态,再兴奋较慢,引起了负色相反应。这种反应加上新看色的色相,形成新的色,所以改变了后看颜色。而且改变的色相还是有规律,是向先看颜色的补色方面改变。
This is because, see the color of the first to make the color of color excitement, nerve fibers immediately look at other colors, other colors nerve excitement quickly sense of color, and look at the color of color check status after the nerve is excited, excited again slowly, hue caused a negative reaction. The reaction with a new look at the color hue, form a new color, so changed after see color. And change the hue or regular, is to look at the color of color changes.
