Canon mg6100 how disable color particles

[luciofonte]

Hi i post the same example maybe you know.

1- i have a cmyk image to print.

2- I start from the yellow, i put it in print and the printer print the yellow image but with very little blue and red dots, and this make a disturbed image. Worst if i put the remains colors, he add those dots for each color and the result is a sum of particles that from a short distance you notice it.

What is the name of this method, option, mode, and how to disable this "add color" that i never ask for it.

Thank you

I found that is dither the problem, there is an option on photoshop to print without dither, a flat pure color?
Thank you

It may be that "dithering" isn't really the issue. Pretty much any color will be printed with a combination of different Cyan, Magenta, Yellow, and/or Black ink. Unless the yellow you were printing was exactly the same "pantone code" as the actual ink (very, very unlikely), it would have to do some mixing.
