The press comes with several options; casters, a wooden shelf under the press. It is also possible to supply the press with a hydraulic pressure system, which guarantees always an even pressure on both sides of the press. You can read the pressure on a gauge.

These presses are driven through a sealed gear box into the lower roller. The heavy wheel, combined with the gear ratio 1:10 make for a smooth action. The hard synthetic plate runs without play between adjustable guide strips, which are mounted on the side frames. Loosening the spindles makes the upper roller raise by spring pressure, in this way facilitating relief printing (lino, woodcut). Shims of leather or cardboard can be placed under the spindles, thus providing more flexibility during printing. Both upper and lower rollers are fitted with ball bearings. These presses are lightweight versions of the JW-series, enabling it to be used in places where, for floor/weight bearing reasons, the JW-series cannot be accomodated.
As far as delivery is concerned, we prefer to ship this press assembled, even if this means disassembling it at site to facilitate delivery.

Option 3. The JPV-70 press can be fitted with a hydraulic pressure system. (Image shows the JZM-150 which has standard a hydraulic pressure system).
A hand pump is used to set pressure. Beneath the pressure screws hydraulic cylinders are located, these push the upper roller downwards. A gauge shows the pressure. This system not only guarantees the same pressure on both sides, but it also gives the possibility to use exactly the same pressure in a following print run.

Normally etching presses are fitted with wooden stops. This prevents the bed from falling out of the press. However, these wooden stops don't offer enough safety according to present day safety standards. That is the reason that these presses are fitted with extra stops (check the arrows), which makes it impossible that the bed will fall out of the press. These safety measures are required in a school environment.
