I believe you might be referring to the Inverse Correction and Centre 
Resolution settings on the 994 board in the Digi 4.  Coring will also
create a "pasty" look if it is overadjusted.  

Since your first post was about sleep mode with Digital Deflection, all 
you need to do is put the DD into sleep mode, period.  This shuts off 
the crt filament voltage, and enables the tube to be completely "dark"
while the machine is still on without poisoning the cathode.
