Inkjet Primaries
Why are red, blue, and yellow inkjet primaries?
For a subtractive printing process, the 'optimum'
primary colors for a 3-ink system would be closer to
magenta, cyan, and yellow. However, these are not
generally used. Why?
I don't know the precise answer but it is no doubt a
tradeoff between cost and which colors are used most
often. For non-photo printing, the straight red,
blue, and yellow are far more useful since they can
be use by themselves or in simple combination to
produce a wide range of vibrant, if not realistic
colors. For example, pure red is far more likely to
be used for simple graphics than magenta. To make
something that looks like pure red using magenta and
yellow requires a precise combination - not easy to
do with an inkjet printer!
