I found out why my D2 head was putting out a lot of light, it's supposed to, it says "D2HI" on the back, LOL!
So I bought another D2 head for not too much money, figure I can use the D2HI for really big prints.
But now I am wondering about that purchase as I just ordered a Stop Clock Vario. It would seem the best way to get the most out of split-grade printing is with using a head like the Zone VI or VCL 4500. Before I start scouring for one of these, does it really make that much of a difference and how does one get the most out of split-grade without a VCL?
