Dont know about Keppro - but Kinsten boards will
go a bit blotchy and loose contrast after 1 or 2
years. (my boards are kept in a fridge)
I have use board that are 3 or 4 years old but
the results where average. The amount of exposure
time needed was 3 times higher than fresh boards
and large black/copper areas didnt hold up at all
well.
I think you need a VERY high contrast phototool
to make up for the lack of contrast of the board.
