This question already has an answer here:
I am trying to print out a simple picture (below) that is composed of sections of the following RGB colors:
I am using this image for color sensing (with a sensor that measures intensity of red, green, and blue light) and need these values to be accurate.
The problem is, when I convert this image to CMYK for printing using an online tool, the equivalent RGB values are not accurate. I was wondering if there's any way to convert an image like this to CMYK for printing while maintaining the RGB values.
