subtractive process

基本解釋

In the subtractive process, colors are produced when dye (as in paint or color photographic materials) absorbs some wavelengths and so passes on only part of the spectrum.
而在減色法中，染料（比如在繪畫顔料或彩色照相材料中）吸收了部分波長而衹允許分光譜通過，從而産生各種色彩。
As the wide application of the subtractive process in the PCB manufacturing, especially in the fine line and HDI fabrication, it becomes more important to improve the yield rate and the line quality .
隨著減成法在PCB制作中的日益廣泛使用和精細化線路發(fā)展的要求，提高良率和線路質(zhì)量越來越重要。
Blue printer: One of the four printing plates in a subtractive colour process which is to be printed in cyan ink.
藍版：減色彩印法的四張印版之一。它需用青藍色墨印刷。
