Estimating the term…
There are provided a regeneration treatment apparatus, a washout processor, and a manufacturing method of a flexographic printing plate in which attachment of a resin aggregate generated as a non-exposed portion of an imagewise exposed flexographic printing plate precursor is removed through development using a washing solution can be suppressed and the resin aggregate can be easily cleaned off even in a case of being attached. The regeneration treatment apparatus removes, from a used washing solution containing the resin aggregate generated as the non-exposed portion of the imagewise exposed flexographic printing plate precursor having a photosensitive resin layer is removed through development using the washing solution of which a main component is water, the resin aggregate. The regeneration treatment apparatus has a centrifuge that has a rotating body for separating out the resin aggregate from the used washing solution and an induction path through which the resin aggregate from the centrifuge passes. A portion in contact with the resin aggregate has a critical surface tension of 31 mN/m or less and a dynamic friction coefficient of 0.2 or less.
A regeneration treatment apparatus that from a used washing solution containing a resin aggregate generated as a non-exposed portion of an imagewise exposed flexographic printing plate precursor having a photosensitive resin layer is removed through development using a washing solution of which a main component is water, removes the resin aggregate, the regeneration treatment apparatus comprising:
A regeneration treatment apparatus that from a used washing solution containing a resin aggregate generated as a non-exposed portion of an imagewise exposed flexographic printing plate precursor having a photosensitive resin layer is removed through development using a washing solution of which a main component is water, removes the resin aggregate, wherein a portion in contact with the resin aggregate is composed of polyethylene having an average molecular weight of 750,000 to 6,000,000.
A washout processor that develops an imagewise exposed flexographic printing plate precursor having a photosensitive resin layer using a washing solution of which a main component is water,
A washout processor that develops an imagewise exposed flexographic printing plate precursor having a photosensitive resin layer using a washing solution of which a main component is water,
