Hexachrome Printing
For most printing conventional colour made up of cyan, magenta, yellow
and black is quite acceptable. Where extra vibrancy and impact is
needed Hexachrome maybe the answer. In the Hexachrome process the
normal cyan, magenta, yellow and black colours of conventional printing
are supplemented with orange and green. This means a much greater range
of Pantones can be reproduced
accurately, and pictures look much more vibrant and life-like.
There are currently no economical ways of proofing Hexachrome. We would
always recommend a small print run to 'prove' the artwork before a
large Hexachrome job is printed

Please make sure that your art/design package supports Hexachrome and exports to a printable file
