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 extends over a radial distance into the bristles of the second brush, said radial distance being at least 15% of the length of the bristles.
A method for treating a relief precursor (P) with a liquid, said method comprising:
- transporting the relief precursor along a support plane in a transport direction;
- treating the relief precursor with a liquid using at least a first brush and a second brush arranged downstream of the first brush and having a rotating axis with bristles;
- wherein during the treating with the second brush, pressure is created in the bristles so that the bristles are squeezed and liquid is removed from the second brush, wherein the pressure is created by having a squeeze element extending over a radial distance into the bristles of the second brush, said radial distance being at least 15% of the length of the bristles.
