Mark,

Every technology seems to have it's own vocabulary which is rapidly 
changing in meaning as technology increases. I also thought it 
referred to a way to increase black with a single plate and pass 
through the press. It's the plates and passes that control the cost. 
Maybe you run the same plate twice with different ink loading to 
punch up the blacks. You pay for the double pass but not the extra 
plate. Just a thought.
