Why do printers have CMYK ink instead of RYB & black ink?
In: 2442
RYB aren’t actually the primary colors. CYM and black are the true primary colors for ink mixing(the K stands for black)
The reason we think RYB are primary is because it’s pretty close to CYM but it uses more common colors. (red is used more often than magenta and blue is used more often than cyan) As a result, lots of schools and art classes just approximate the primary colors as RYB.

guess rgb was the way CRT displays worked (fat monitors with electron beams) . in the times I did renderings and photoshop work it was a f hell to get in print what I was doing om my twin fad 20 inch cathode screens.

I work with silver halide (laser) printers. They print by blasting the silver crystal infused paper with certain wavelengths of light, which modifies the color after a few chemical processes. Our photosensitive paper contains the pigments CMYK in a gel layer, but we read/calibrate the printer lasers using RGB.
The conversion is pretty simple. Red light corresponds with cyan pigment, green with magenta, and blue with yellow. They are inverse relationships: The more red, less cyan. The less yellow, more blue. The “key” (density) is the depth and intensity of the color contrast, which is modulated with black pigment.
Say you needed to make your prints slightly more cyan to achieve color accuracy – you would actually subtract a “point” of red light from the laser for each “point” of cyan you want to add to the print. You add green to reduce magenta, subtract yellow to increase the blue, etc. Density is a direct (not inverse) relationship – black is just black.
