Remarks
A4 Projection	The projection is called A4 because it fits very well on a landscape A4 sheet of paper.
Ciric I	The Ciric I projection is based on the Winkel-Tripel and optimized for 54 degrees of acceptable angular distortion and 150% acceptable areal distortion, with parallel bending increasing linearly with latitude, and with equally-distributed meridians. (Quoted from the Flex Projector Gallery)
recommended comparisons
A4 Projection	Ciric I Dedistort
Ciric I	A4 Projection Dedistort Winkel Tripel
This pairing is among the list of recommended pairings – but why? While very much alike at first glance, in direct comparision the differences become quite obvious.
