John,
     
     According to my copy of IPC-SM-840 (May 1988):
     
     Type A--Deposited Image
        1. Liquid
        2. Dry
     
     Type B--Photo Defined Image
        1. Liquid
        2. Dry
     
     So Type B-2 is Dry Photo-Imagable Solder Mask

I do not have a copy of the above publication.  Could one of you be so kind
as to let me know what "Type B-2" calls for.
