Digital BW, The Print

Amen to that! There's a thread here I'd really like to benefit from
but first I'll have to jump in and ask about some abbreviations. I do
Black Only with 3MK - and that's about the only set of initials I
understand! K is for black as in blacK - I finally figured that out.
And M is for matte... but PK is gloss black, it means "Photo" black, I
guess on the assumption that originally black and white photos were
glossy. Beyond that, I'm lost. I hope you get some good answers!
