The simplest approach to creating a black and white image is taking a color image and converting it
to grayscale in an imaging program such as Photoshop or Illustrator. In addition, although converting
an image from color to grayscale is easy, the opposite operation is complex, in this case it is better to
have it in color in the first place.
There are different ways to print a black and white image, normally once the colors are converted to
grayscale, the black in the highlights and midtones is substituted for color inks. This occurs because a
six-color printer with light colorants (a CMYKcm configuration) is unbalanced in the sense that the
darkest ink, K (black), does not have a light counterpart like the C (cyan) and M (magenta) inks. As a
result, K ink must not be used in highlighted image areas in order to prevent a grainy appearance.
But, while you gain in print quality you lose in the neutrality of black.
This guide is focused to achieve a neutral black in the print, avoiding the black substitution.
