Advances in rapid prototyping technologies have led to the emergence of three-dimensional printers which can
fabricate physical artefacts, including the application of surface colours. In light of these developments, this paper asserts
that the need to print colour accurately is just as important for designers using three-dimensional colour printing as it is
for two-dimensional inkjet printing.
Parallels can be made with two-dimensional digital Inkjet printing and 2D common problems include: on screen previsualisation,
colour management methods, colour gamut and maintaining colour accuracy. However, for three
dimensional colour printed objects, there are more variables that will affect the finished colour. These are: the powder
and process inks, unevenness of the surface, wax post-processing and other infiltration media and procedures.
Furthermore, in some 3D printers, the K channel is replaced by the binder and so the printer is only using the cyan,
magenta and yellow channels.
The paper will suggest methods for improving pre-visualisation and accurate pre-viewing of the colours through the
manufacture of three-dimensional colour charts as a reference guide for designers so that they can make accurate
coloured artefacts. A series of case studies will be demonstrated.
