Digital BW, The Print

As someone who has recently converted a 4800 from K3 to NK7 inks and 
does not have any plans to revert back in the forseeable future I am 
seeking advice re: using OHP to make transparencies. Previously I used 
my good old 2000P and OHP to make these but I'm now planning to do 
larger transparencies with the 4800. 

Any advice I can get (dry times, platen settings, manual feed, after 
coatings etc.) before my first go would be appreciated.

Thanks.
