: Mixing cmyk colours I have a cmyk colour of 0,40,50,0 I want to change the magenta value, the 40%, to redder colour 0,67,70,28 And see what the resulting CMYK colour is. How I can go

@Turnbaugh909

A) You can't create a CMYk color where any value is above 100%. There's no feasible way to mix your CMYk starting point with another CMYK color in terms of press ink. 100% is the maximum allowable value for any CMYK color.

B) For press, there may be a couple ways to handle this. i.e. You run a second pass.. print the first pass as 0/0/50/0 then overprint a second pass of 0/67/70/28. However, this is going to considerably darken all colors not just magenta areas. The magenta areas would end up being your brown/red but that extra yellow and black overprint is going to darken all other areas.

So really.... what color you are trying to achieve is kind of mystery....



As you can see that 50% yellow is going to alter everything even if you remove magenta and overprint your color.

If you really want to merely replace Magenta with your brown/red.. you could run a 5 color job (CMYK+1) leaving the Magenta plate empty. Areas where Magenta was not empty are going to create a deeper red....



(Pantone 471 is merely the color I felt was closest to 0/67/70/28, you might pick a different spot. I didn't spend a great deal of time looking and there is no immediately matching spot color I saw.)

Ultimately, it may be possible. However, much more detail as to why you need this, what your process is, and your end goal would assist in a better answer.
