Here, however, you'd better ask a question in French, otherwise the question is translated into French by machine and might become unintelligible.
I asked a question in French about the method used in printing the Monaco 1962 Multiple Sclerosis stamp (Scott 506) evidently printed on a Taille-Douce-3-colour press (TD-3) in more than three colours in just one run.
Here's my tentative translation
of alfred's answer:
"Hello Florian,
In answer to your question: this stamp was printed by means
of double inking, improperly called "camaieu" by the I.T.P. printers. The inks are applied successively to parts
of the same printing cylinder by means
of precise cutting
of the inking rollers, the red ink and the blue ('black' used here by mistake) ink are superimposed in the same place. This method
of colour printing is extremely difficult to keep in tone/tint. Used for Monaco or, at one time, for some oriental countries, such as Cambodia or Laos, which also had camaieu printings, due to an increased percentage
of defective sheets.
Regards,
alfred"
In my opinion, the French expression "en camaieu" or "tint/tone on tint/tone" leads, by extension, to "ink on ink", which explains the French I.T.P. printers' new use
of the old term.
"Camaieu" printings were used extensively for most French-speaking countries
of Africa as well (these ordering small printings only where the danger
of defective sheets printed was not great).
Later on, an additional post on Pierre Albuisson's site appeared reading:

This is a question I asked myself too! There were just 3 ink-rollers and by precise overlapping
of the red, blue and yellow you can get the additional brown, purple and green!
