关于明大那个色域问题，老鬼的解释~(我就懒得翻译鸟~~)
In FM, you print a lot of small dots. As the dots are smaller, also the ink thickness is less than in conventional AM. This might sound strange, but the thinner the ink layer, the more 'pure' the ink is transferred onto the substrate.
A good example is: take a glass of water out of the ocean and hold it against the light. It will look clear and transparant. However, if you look at the ocean as a whole, it looks grayish and dirty (around here it does :-) ). That's because the small particles influence the fraction of the light and the more volume, the more particles. This influence of fraction causes desaturation of ink.
In other words: by printing a thicker ink layer, you will get a less saturated result.
FM dots and special AM screens such as Concentric Screening from EskoArtwork reduce the ink layer thickness, therefor improving the overall gamut.
