Yeah back in the day we had a 4 sided aluminum angle iron thingy
held together with springs... Very inexpensive, worked like a charm, but would go past table if
pushed too hard.
Once printed pile of nylon jackets w/ a 3 color print and got talking while in process...
laid a "wet" one in the pile and thought- oh noooo- yes smeared all over the back of the other.
Xylene fix...only back in the day.
