    摘要： According to the present invention, there is provided an apparatus for processing a photographic sheet (9) which comprises at least one station (4) with inlet and outlet pressure roller pairs (42 to 45) for transporting said sheet, spray means (22) for spraying processing liquid (21) onto at least one surface of said sheet, characterised in that said station comprises sealing means for maintaining a liquid seal (58, 59) between at least one roller of at least one roller pair and an adjacent wall of the washing station. The present invention also provides an apparatus for making an offset printing plate according to the silver salt diffusion transfer process, using the described station (4) as washing station. The present invention also provides a method for making an offset printing plate using the above described apparatus for processing an imaging element.

    摘要： The present invention provides a method for making a lithographic printing plate according to the silver salt diffusion transfer process using a photographic material comprising on a support a silver halide emulsion layer and a layer containing physical development nuclei comprising the steps of:

    image-wise exposing said photographic material and
    developing a thus obtained image-wise exposed photographic material by guiding said image-wise exposed photographic material through an alkaline processing liquid in 15s or less;
    characterized in that said alkaline processing liquid comprises a hydrophobizing compound having a mercapto group that has a pK a of 4.5 or less.
