Different devices conceive colors differently, and pure red color that appears on your monitor is not likely to appear exactly the same on your printer. That’s why you need to deal with color profiles. Color profile is a multi-part filter that goes between your computer and other devices. If your goal is for all the applications to show the photo the same as it looks on different machines, and the prints to match the display, ImageConverter Plus has a perfect color profile management system. Color profile operation allows 3 parameters: ignore color profile, use built-in color profile, and use external color profile depending on your needs. The main goal for the colors and tones in your image to be displayed as accurately as possible. When you assign a profile you are not changing the red, green, and blue code values; you’re changing how those values are interpreted, and how the image will appear. https://www.imageconverterplus.com/features/color-profile/
