Adjustable bed press
- In any case, however, the idea would have been to bring the printing
surface up to the proper level to work with the rollers and the
properly packed cylinder, not to control the AMOUNT of impression!
That should be taken care of by packing, the printing surface should
be at the proper height for the inking rollers. The bed would raise
and lower to accomodate the thickness of the medium.
