A method and apparatus for inspecting a photolithography mask for defects is provided. The inspection method comprises providing a defect area image to an image simulator wherein the defect area image is an image of a portion of a photolithography mask, and providing a set of lithography parameters as a second input to the image simulator. The defect area image may be provided by an inspection tool which scans the photolithography mask for defects using a high resolution microscope and captures images of areas of the mask around identified potential defects. The image simulator generates a first simulated image in response to the defect area image and the set of lithography parameters. The first simulated image is a simulation of an image which would be printed on a wafer if the wafer were to be exposed to an illumination source directed through the portion of the mask. The method may also include providing a second simulated image which is a simulation of the wafer print of the portion of the design mask which corresponds to the portion represented by the defect area image. The method also provides for the comparison of the first and second simulated images in order to determine the printability of any identified potential defects on the photolithography mask. A method of determining the process window effect of any identified potential defects is also provided for.

Mask simulation tools are typically extremely complicated to learn and to use effectively. Therefore, providing access to a mask simulation tool over a wide area network (WAN) to multiple on-line users can be very cost effective. Specifically, in a network-based simulation server, multiple users can view the same mask image, simulations, and analysis results and provide real-time comments to each other as simulation and analysis are performed, thereby encouraging invaluable problem-solving dialogue among users. The user interface for this mask simulation tool can advantageously facilitate this dialogue. For example, the user interface can include an enter box for a user to enter a message and a talk box for capturing any message sent by any user of the simulation tool using the enter box.

A presensitized plate in which an image recording layer is formed on a support for a lithographic printing plate obtainable by performing a treatment with an aqueous solution containing one or more divalent or multivalent cations at a concentration ranging from 0.0001 mol / L to less than 0.020 mol / L is excellent in both scum resistance and press life when processed into a lithographic printing plate.

A method of making a lithographic printing plate is disclosed which comprises the steps of(1) providing a lithographic printing plate precursor comprising (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer and (ii) a coating provided thereon which comprises hydrophobic thermoplastic polymer particles;(2) exposing the precursor to IR-light or heat, thereby inducing coalescence of the thermoplastic polymer particles at exposed areas of the coating;(3) applying a hydrophilic protective layer on the coating; and then,(4) while the precursor is mounted on a print cylinder of a printing press, developing the precursor by supplying an aqueous dampening liquid and / or ink to said precursor while rotating said print cylinder whereby the coating and the hydrophilic protective layer are removed from the support on the non-exposed areas.According to the above method, the hydrophilic protective layer can be applied by coating a solution by means a spray nozzle or a jet nozzle and wherein the applied hydrophilic protective layer improves clean-out in an on-press development.

A primer layer that includes a surface-tension modifier dispersed within a polymer binder is disposed between the imaging layer and the substrate of a lithographic printing member to inhibit the production of thermal degradation products that disrupt the oleophilicity of the exposed imaged areas, thereby improving print-making performance and efficiency. In addition, embodiments of the primer layer inhibit static charge buildup during production and during the print-making process.
