How highlight color is created
A document with highlight color contains one color plus black.
The color may be printed either as a solid color or combined with
black. The NPS/IPS prints the highlight color by printing small
dots in a single pass with near-perfect registration. The following
methods are used to create various tints, shades and tones:
• Tints of black or the highlight color are created by printing
dots of black or color with white space between them, thus
producing a percentage value of the color. An example of this
is gray or pink.
• Shades are created by printing black dots next to dots of the
highlight color. An example of this is dark red.
• Tones are created by printing a combination of black dots,
color dots, and blank space. The result is a percentage value
of black and the highlight color. Dark red is made by mixing
dots of red and black. Gray-pink is made by mixing red dots,
black dots and some blank space.
• The patterns of dots are known as screens. Screens are
defined in the printer controller software as a matrix of bits,
which correspond to printed dots. The screen defines which
dots in the matrix are black, which are highlight color, and
which are not printed.
