There were two types of paper, Wiggins Teape and KP5D, but I know very little about this era.
Hi Horamakhet
The stamp was issued on two types of paper, Wiggins Teape (issued 1971) and KP5D (issued 1973), both incorporating Helecon.
What is KP5D? - From 1964 to 1971 stamp papers were produced to reflect the quality of the reproduction and the Post Office requirements relating to the facer cancelling machines. Technical printing problems relating to the clarity of the finished print had to be solved when phosphorescence was introduced into the paper.
In 1964 experiments and trials conducted by Samuel Jones at their Keon Park, Victoria factory resulted in the acceptance of KP5D (Keon Park Fifth Trial Making, Sample D).
Both stamps were printed using blue, orange, brown and sepia ink. The difference in shading is due to the type of paper used.
The coarser paper is Wiggins Teape resulting in a darker shade of colour, the KP5D having a smoother texture will have the lighter shade.

Hi to all
I am not sure if I showed these stamps previously
The stamp on the left is definitely a different colour in the main vignette than the one on the right. It looks like the darker brown colour has not been added.
I have another one, but will have to do some searching to find it
Were there printings on different papers that would account for it?
