涂装颜色培训课件详解.ppt

匹配色方法 目前配色的主要方法是： 目测加上配合使用色差仪。 目视评定: 目视评定就是在合适的光源条件下，将需要比对的颜色件放在靠近的位置上，直接观察二者颜色是否一致，进而得到色差情况的判断。 色差仪测量： 色差仪就是测量色差的仪器，也可以按照使用原理称为多角度分光光度仪。色差仪测量是指使用色差仪对车身、外饰颜色件或色板进行测量，并将获得数据与颜色基准数值进行比对 七、色差控制 白色和银色这种颜色饱和度低的颜色，色差很容易被察觉，但在亮度L上的差异不易被察觉，但在色相a和b上的差异就很容易被察觉。 对于鲜艳的颜色，即饱和度高的颜色，颜色上的变化不容易被察觉。例如北京现代RT9红，a值在38~45，b值在26~32。 1、了解每个主机厂车身状态，保持数据必威体育精装版，并制定色差控制标准。 2、对于新油漆或是放置较长时间没有使用的油漆，先进行调试生产喷涂。（铝粉变形、卷曲） 3、对于依照标准板为准的颜色，应结合△E及标准板的标准值综合分析颜色属性后，给出L、A、B调整方向。一般情况下△E在1.2之上时目视可以分辨。 4、色相需保证与车身相同，新项目新颜色每批产品均需与车身进行目视匹配，确定后续调整方向，色差控制和优化，实际是一个不断摸索、持续改进的过程，需不断的努力和总结经验教训，才能把色差工作做得更好。 谢 谢 * * * * The Basics of Colour Vision Colour vision deficiency, or colour blindness, is the inability to distinguish certain colours. The majority of colour blind cases are hereditary, although deficient colour vision may be acquired as a result of another eye disorder. Colour blindness affects about 8% of men, and approximately 0.5% of women1. This is because the gene for colour blindness is X-linked recessive - meaning that colour blindness manifests only when there is no corresponding normal colour vision gene. Since men only have one X chromosome, the chances of colour blindness showing up in men are much higher than in women, who have two X chromosomes. However, women may be carriers of the colour deficient gene, but not experience colour defective vision. To understand defective colour vision, ‘normal’ colour vision must first be understood. * Once separated, the chips can be ordered in the following manner: Achromatic chips can be ordered from light to dark. - This is called the lightness dimension. Artists sometimes refer to this dimension as 搗alue. Colored chips can be sorted as to their predominant color and intensity. The most intense chip from each color group could be selected and arranged according to the visible spectrum (violet, blue. blue-green, green, yellow, orange, red). Once arranged, the ends can be joined together to form a circle.
