A computer-implemented method, apparatus, and article of manufacture optimizes publication layouts using a genetic algorithm approach. In a timely manner, the computer-implemented invention generates and evaluates a large number of publication layouts and selects the optimum layout. The optimal layout has an optimal relationship between the placement of advertisements and stories on the pages of the publication, the maximization of revenues, and the minimization of printing costs.

The present invention provides a method for making a lithographic printing plate according to the silver salt diffusion transfer process comprising the steps of image-wise exposing an imaging element comprising on a support a photosensitive layer comprising a silver halide emulsion and an image receiving layer containing physical development nuclei and developing said imaging element in the presence of developing agent(s) and silver halide solvent(s) using an alkaline processing liquid characterized in that said development is carried out in the presence of a regulator according to one of the formulas as specified in the claims. The present invention further provides an imaging element and alkaline processing liquid for use in said method.

Method for making a lithographic printing plate according to the silver salt diffusion transfer process

According to the present invention there is provided a method for preparing a silver complex diffusion transfer reversal material comprising a grained and anodized aluminum foil as support and a photosensitive silver halide emulsion coating, characterized in that said grained and anodized aluminum foil is corona treated in a corona station comprising a roller and at least one electrode, that has been coated with a dielectric coating before said foil is coated by a photosensitive layer.

A method for preparing an aluminium foil for use as a support in lithographic printing plates

The invention relates to a method, a system and a computer programme for making an image area correction in a printing system. Print data are provided in a logical page order corresponding to at least one signature (25), for printing. At least one parameter of a recording medium (6) on which the print data are printed is determined, this parameter being relevant to the position of the printing format on the recording medium (6), which is folded according to the signature. The position of the pages is then corrected according to this parameter prior to printing, in such a way that the print formats of successive pages of the finished signature are positioned accurately.

Method and system for imposing print data

The present invention provides a lithographic printing plate material which comprises a grained and anodized aluminum support and a silver halide emulsion layer between which physical development nuclei are provided wherein said aluminum support have 500 or more pits having a diameter of 0.03-0.30 μm and an average diameter of 0.05-0.20 μm per 100 μm2.

Disclosed is silver halide cubic crystal having a depression on each face thereof and/or a hollow portion formed by joining of the depression with other depressions. This crystal may be produced by precipitating first monodisperse cubic type silver halide crystals and then precipitating second silver halide having a lower solubility than the first silver halide crystals by controlled doublejet precipitation method to dissolve the first silver halide crystals. There are also disclosed a silver halide photographic emulsion comprising such silver halide crystal and a silver halide photographic high-sensitive material containing said silver halide to which a spectral sensitizing dye is adsorbed.

A control for a marine propulsion unit including a water propulsion device powered by an engine through a transmission. The transmission has forward, neutral and reverse positions. The engine has at least one combustion chamber, an air and fuel supply system, and at least one ignition element corresponding to the combustion chamber for igniting an air and fuel mixture supplied to the combustion chamber. The control is arranged to delay the firing of the ignition element when the engine is idling from a normal firing timing, and arranged to advance the firing of the ignition element if the engine speed rapidly reduces and the position of the transmission is changed from neutral to reverse or forward.

In a page arrangement order determination method, when a plurality of pages are to be arranged on a common surface for printing purposes, the order of arrangement of the plurality of pages on the common surface is determined based on only the order of folding of printed paper and a position of a front page. A cutting step required for a work-and-tumble operation and a repeat operation can be effected between a printing step and a bookbinding step, and when one of the work-and-tumble operation and the repeat operation is to be effected, the page arrangement order is determined only by additionally designating the one of the two operations.

Page arrangement order determination method

The present invention provides a lithographic printing plate material for silver complex diffusion transfer process by scanning type exposure which comprises a film support and, provided thereon, at least a silver halide emulsion layer and a surface physical development nuclei layer, wherein water content in the whole lithographic printing plate material including the support is 1.5% or less. Preferably, the silver halide emulsion comprises about 95 mol % or more of silver chloride, 90% by weight or more of the silver halide grains have a size within ±40% of average grain size, the silver halide grains have an average grain size of about 0.3μ-about 1.0μ, and the surface of the grains is replaced with about 0.1 mol %-about 3.0 mol % of an iodide per 1 mol of the silver halide.
