I believe that it would be possible to use an Arduino to see a registration mark using say a Pixy camera and control X & Y motors in combination with a high resolution encoder connected to the drive shaft to maintain registration on a printed surface. Does anybody have any ideas as I am willing to work in partnership with you?

Have you done any tests to verify that belief? Are all the motors and associated hardware already in use?
Yes
This would act as a bolt on mod

My Boss is like most very tight with cash, but if i can put a prototype idea together then there is a possibility that cash maybe available. need proof of concept first
Two proofs are necessary.
First can the motors be controlled, positionally, by an Arduino.
Second, can you program the camera to picture what you want and can you interpret the image to relate to the position of the motors?
To answer to your first question I believe yes, as both motors require forward and reverse, the camera would be required to have a pre-defined registration mark stored to allow a detection of movement then using encoder data move the motors accordingly
Finally, the key question. Do you have an identical system that can be used for testing as the software is being developed? Can you ship that system to the programmer that will write the code, or will the software have to be tested using remote control with you in the middle?
A gravure printing press is not something you can just ship.
I wish I could help because I minored in printmaking and combining a new hobby with an old one would be awesome.
Well, then the OP will HAVE to use a spare unit for developing the software.
This might be a silly question: Why doesn't the printer have this built in, or at least have it as a factory or after-market option already?
The need for registration seems pretty fundamental to me.
The Press unfortunately cannot be moved easily. But a mock up could be made at LV. But I’m not opposed to have live testing on site??
Is the system intended to adjust sidelay and length dynamically during the printing process or is it part of initial setup before a print run?
Why not get that fixed?
You do understand the current system will NOT be usable while it is modified for testing, and may be damaged?
