Abstract
An apparatus for treating a relief precursor with a liquid includes a housing, a conveying mechanism for transporting the relief precursor along a support plane in a transport direction through the housing, and a treatment section for treating the relief precursor with a liquid. The treatment section includes a plurality of brushes arranged in the housing for treating the relief precursor, the plurality of brushes including at least a first brush and a second brush downstream of the first brush and having a rotating axis with bristles. A squeeze element squeezes the bristles of the second brush and extends over a radial distance into the bristles of the second brush. The radial distance is at least 15% of the length of the bristles.

An apparatus for treating a relief precursor with a liquid, said apparatus comprising:
- a housing;
- a conveying mechanism configured for transporting the relief precursor along a support plane in a transport direction through the housing;
- a treatment section for treating the relief precursor with a liquid, said treatment section comprising a plurality of brushes arranged in the housing for treating the relief precursor, wherein said plurality of brushes comprises at least a first brush and a second brush arranged downstream of the first brush and having a rotating axis with bristles;
- and
- a squeeze element arranged to squeeze the bristles of the second brush;
- wherein the squeeze element is a bar having a round or oval cross section.
An apparatus for treating a relief precursor with a liquid, said apparatus comprising:
- a housing;
- a conveying mechanism configured for transporting the relief precursor along a support plane in a transport direction through the housing;
- a treatment section for treating the relief precursor with a liquid, said treatment section comprising a plurality of brushes arranged in the housing for treating the relief precursor, wherein said plurality of brushes comprises at least a first brush and a second brush arranged downstream of the first brush and having a rotating axis with bristles;
- and
- a squeeze element arranged to squeeze the bristles of the second brush;
- wherein the squeeze element is configured to bend the bristles of the second brush over an angle β which is larger than 20°, preferably larger than 30°, more preferably larger than 45°.
An apparatus for treating a relief precursor with a liquid, said apparatus comprising:
- a housing;
- a conveying mechanism configured for transporting the relief precursor along a support plane in a transport direction through the housing;
- a treatment section for treating the relief precursor with a liquid, said treatment section comprising a plurality of brushes arranged in the housing for treating the relief precursor;
- and
- a cleaning section for removing debris and/or liquid from the relief precursor, said cleaning section being arranged downstream of the treatment section, wherein the cleaning section comprises a lower removal roll arranged to rotate in contact with a back side of the relief precursor and an upper removal roll arranged to rotate in contact with a relief side of the relief precursor, wherein the upper removal roll is arranged opposite the lower removal roll, on opposite sides of the support plane;
- wherein the lower removal roll is configured to apply more pressure on the relief precursor than the upper removal roll.
