The "right" black - which CMYK value to use?

 Which color code provides the best black shade is and remains controversial. Our experience has shown that you can achieve a deep black in areas and shapes with the Cmyk code C 30, M 30, Y 30, K 100. Texts and lines, on the other hand, should only be created in a pure black: C 0, M 0, Y 0, K 100, otherwise undesirable color results may occur. Please note that this is only a recommendation. Tastes are quite different in this color range.
