Short for
Cyan-Magenta-Yellow-Black, and pronounced as separate
letters. CMYK is a color model in which all colors are
described as a mixture of these four process colors. CMYK is
the standard color model used in offset printing for
full-color documents. If we print cyan, magenta and yellow
inks on white paper, they absorb the light shining on the
page. Since our eyes receive no reflected light from the
paper, we perceive black... in a perfect world! The printing
world operates in subtractive color, or CMYK mode. In
practice, printing subtractive inks may contain impurities
that prevent them from absorbing light perfectly. They do a
pretty good job with light colors, but when we add them all
together, they produce a murkybrown
rather than black. In order to get
decent dark colors,
black ink is
added in increasing proportions, as the color gets darker and
darker. This is the "K" component in CMYK printing. "K" is
used to indicate black instead of a "B" to avoid possible
confusion over Blue ink. See the figure below to get a
clearer view.
What is Hexachrome?
Hexachrome™ is an
ultra high fidelity six-color printing process developed by
Pantone*, Inc. Pantone* has drawn on extensive research in
color systems to develop their HiFi system. Hexachrome™
provides dramatically improved color range and accuracy over
four-color process printing. Hexachrome™ is a fully-integrated
process with a complete support infrastructure. What are the colors used in
Hexachrome™? The special ink set developed by
Pantone*, Inc. is purer than traditional ink sets and consists
of enhanced versions of the subtractive primaries yellow,
magenta and cyan, along with black, vivid orange and green. In
addition to utilizing the six-color set to print in
Hexachrome™, the CMYK components can be utilised for
four-color jobs with enhanced results while minimising press
preparation time between CMYK and Hexachrome™ jobs.Hexachrome™ is capable of simulating over
90% of solid Pantone*
Matching System Colors almost twice the number that can be obtained using
conventional four-color process printing. Using
only six colors. Hexachrome™ generally eliminates the need for
additional colors. koolprint.co.uk! The only online printing company offereing Hexachrome™ printing process

Offset Printing
A printing technique whereby ink is spread on a metal
plate with etched images, then transferred to an intermediary
surface such as a rubber blanket, and finally applied to paper
by pressing the paper against the intermediary surface.
koolprint.co.uk uses offset printing to produce large volumes of
high-quality documents. Although the equipment and set-up
costs are relatively high, the printing price is relatively
inexpensive
