Normally this press will be assembled in the printmaking studio by Polymetaal employees or by associates who have our permission to do the assembly or disassembly.

It is important to check out first if the crate can enter the building. Also important to choose, together with Polymetaal, the way of transportation.
If the press has been delivered to you in a crate, the crate must be taken apart with care. Remove the screws that keep the press on the pallet. Now the press needs to be lifted from the pallet, either with a 2 tons tackle block or with a forklift truck.
When the press is on the ground, the press must be adjusted. For that purpose the press has four "adjustable feet".
Now the press is ready for use.
This press works in general the same way as any other etching press; the paper, blanket(s) and plate are positioned on the bed and passes through the rollers under pressure. Some features of this press make printing easier, like the hydraulic pump to set pressure on the top roller. Other features make is safer, like the anti-overload-coupling. Some features make it easier to work accurate and precise, like being able to read the exact pressure of the top roller.
Use of the press
The purpose of the felt is to press the paper into the small engraved lines of the plate, in order to accept ink.
Printing woodcuts and linocuts with this press
The drawing shows a layer of felt. This felt has also the feature to compensate for irregularities of the woodcut or linocut. (differences in thickness). If the woud or lino should be perfectly plane, no felt was needed. Underneath the felt is a plastic layer (PVC) of appr. 5mm thick. This is only functional in combination with the felt. If the PVC layer should not be used, the felt would press the paper into the hollows of the woodcut or linocut. If you want embossing, very well. If not, prevent this from happening by using the plastic layer.
