Besides full tone areas, printing halftones is also possible on the risograph. There are various options available for reproducing multicoloured images like in offset or digital printing. Depending on print method, substrate and context, these colour levels are generally called separations, positives or plates. If three masters are created, it is possible, to create a three-colour print with the risograph by successively printing them on the same substrate. If image areas overprint in two or more image areas, new colours emerge because the colours in the risograph are glazing and mix in the areas where they overlap. These colour separations can be seen as greyscale images, which can have an ink coverage between 0 and 100%.
So a full-tone coloured area of an image features 100% of the respective colour, whereas lighter areas of the image feature lighter shades as well. It should again be noted that the colours of the four-colour euro scale, cyan, magenta, yellow, and black, are not available for the risograph.
