    Abstract: According to the present invention the storage stability of a diazo based imaging element can be improved by controlling the amount of free water in the imaging element. Thus the present invention provides an imaging element comprising on a support a hydrophilic layer containing a hydrophilic (co)polymer or (co)polymer mixture and having been hardened with a hydrolyzed tetraalkyl orthosilicate and a light sensitive layer containing a diazo resin or a diazonium salt characterized in that the total amount of free water in said imaging element satisfies the following formula (I):FW (g/m.sup.2).ltoreq.0.0043 * WS (g/m.sup.2)+0.46 (g/m.sup.2) (I)wherein FW represents the amount of free water and WS represents the weight of the support of the imaging element.

    Abstract: A method of making a heat-sensitive lithographic printing plate precursor is disclosed which comprises the steps of (i) providing a web of a lithographic support having a hydrophilic surface; (ii) applying on the hydrophilic surface of the web a coating comprising a phenolic resin; (iii) drying the coating by supplying heat to the coated web; (iv) a cooling step wherein the web temperature is reduced at an average cooling rate which is higher than if the web would be kept under ambient conditions but not higher than 30° C./s; and (v) winding the precursor on a core or cutting the precursor into sheets. The cooling step provides a significant improvement of the aging behavior of the precursor. A stable sensitivity is obtained shortly after coating.

    Abstract: An off-press plate-making apparatus is provided which comprises an apparatus for removing the lithographic image from the substrate of a used printing master and an apparatus for recoating the recycled substrate with a new image-recording layer. The off-press cleaning and recoating of the substrate provides a short press down-time. The recoated substrate forms an imaging material which can be exposed either on-press in a digital press comprising an integrated exposure apparatus or off-press in an exposure apparatus, which can be integrated in the plate-making apparatus or mechanically coupled thereto.

    Abstract: A method of making a lithographic image is disclosed, which comprises the steps of providing a lithographic imaging material comprising a support and a heat- or light-sensitive coating; image-wise exposure of the coating to heat or light, thereby obtaining a latent image in said coating, the latent image consisting of a set of exposed areas in the coating and a set of non-exposed areas in the coating; development of the latent image by supplying a processing liquid to the coating and evacuating, by means of a suction device, the processing liquid together with (i) substances removed from the exposed areas without removing such substances from the non-exposed areas or together with (ii) substances removed from the non-exposed areas without removing such substances from the exposed areas. The method is especially suitable for processing a lithographic printing plate while it is mounted in a plate-setter or a printing press, without the risk of damaging or contaminating electro-optical components of such equipment.
