Color conversion between different ICCs of the printer
ICC is an international universal color management system. In order to reduce the color difference and the color difference caused by color conversion, a set of standards compatible with various color input and output terminals is specified; in the photo printer and UV printer or other devices, the color is There are four ways to switch between different ICCs.
Here are:
Perceived, Relative Hue, Saturation, Absolute Hue (found in the photoshop color management panel and converted to profile panel).
This is the most commonly used conversion method. This method changes all colors in the source device's color space while keeping all colors invariant, but leaves all colors in the overall sense unchanged.
This is because our eyes are more sensitive to the interrelationships between colors and are less sensitive to the absolute value of the colors. It is more suitable for the relatively small CMYK color gamut conversion of the RGB color gamut of the sedan.
Simple understanding: It can be called overall compression. The advantage is that the contrast between all the colors on the image can be maintained.
The disadvantage is that every color on the image changes, and you can often see the overall image become lighter.
It stays bright but the colors are inaccurate.
(media-relative colorimetric rendering intent)
Relative chromaticity is to accurately replicate all colors in a good domain, crop out the colors outside the gamut, and convert the cropped colors to their closest reproducible colors. The relative chroma reproduction intent is a better choice than the perceived rendering intent for image copying because it retains more of the original color. Suitable for conversion between ICCs where the color gamut is not too different, such as: Japanese prepress CMYK's ICC is converted to U.S. ICC.
Simple understanding: try to meet the original. The advantage is that most colors do not change, but the disadvantage is that the individual colors that go beyond the color gamut change greatly.
