Getting good contact with negatives over 8X10 is a problem everywhere
and for really large negatives I would recommend a vacuum frame. I
have two different Great Bassin printing frames that I use for 7X17
and 12X20 negatives and although they usually give me good results
there is no question but that the vacuum easel is better for prints
this size. Prints made with the vacuum easel just seem to have a bit
more snap, which I attribute to slightly tighter contact.
