摘要:
There is a demand for arylpararosanililinesulfonic acid pigments which, even when the pigment content is relatively low, produce on dilution with customary printing varnishes a printing ink having satisfactory rheological properties. The invention relates to such pasty pigment formulations containing(a) 5 to 50% by weight of an arylpararosanilinesulfonic acid pigment,(b) a long-oil alkyd resin having an oil content of 70-80% by weight whose oil content is based on the reaction with a drying, semidrying or nondrying oil or with a mixture of a plurality of these oils or with corresponding fatty acids whose dicarboxylic acid compontent is a mixture of isophthalic and orthophthalic acid, a small proportion of one or more .alpha.,.beta.-unsaturated dicarboxylic acids and, possibly, anhydrides thereof and whose polyalcohol component contains a mixture of glycerol and pentaerythritol,(c) a hydrocarbon resin having an average molecular weight within the range from 600 to 1700, the amount of which is 1-1.5 times that of alkyd resin b,(d) a phenolic resin modified colophony resin or a cyclized rubber resin or combinations of the two resins and also(e) mineral oil.The formulations are produced analogously to conventional flush pastes consisting of components a, b, c and e, except that in the flushing process, before or during the removal of the remaining water, the resin of component d is added and incorporated.

The invention relates to readily dispersible strong pigment formulations containing arylpararosanilinesulfonic acid pigments of the formula ##STR1## and a polyester resin which has been water-solubilized by neutralizing the carboxyl groups with nitrogen bases.The pigment formulations are distinguished by being very readily dispersible in the various printing ink binders and by having a high tinctorial strength.
摘要:
The invention relates to pasty pigment formulations of pigments of the arylpararosanilinesulfonic acid series, which are free of aromatics-containing mineral oils and are suitable for preparing printing inks, in particular letterpress and offset printing inks. The pigment formulations are obtainable by flushing aqueous presscakes of the pigments by means of the solution of a flushing resin in aromatics-free mineral oil and preparing the flushed paste obtained with an oil- or fatty-acid modified alkyd resin.

A color measurement on printed materials produced by a printing press is performed by at least a first color measuring device installed in the printing press and at least a second color measuring device. A signal is output by the first color measuring device in the printing press when the measured color values registered on the printing materials are located within a predefined tolerance limit for a predefined period and that, after the signal has been output, a color measurement on one of the printed materials thus produced is performed with the second color measuring device.

The invention relates to a trimming strip for the shaping of cigarettes and/or filters, comprising at least one warp thread and several weft threads. The at least one warp thread comprises several fibres made from a liquid crystal polymer and at least one further fibre which has a greater roughness than the fibre made from liquid crystal polymer.
摘要:
A method and a measuring device are proposed for controlling the color application of a printing press (10) using at least one ink-feeding device (20) on the basis of spectral reflectance values of printed surface elements (24) on a print substrate (22), which are distinguished in that measured spectral reflectance values are converted into corrected spectral reflectance values. The method and/or the measuring device can be advantageously used in a printing system having a printing press (10), to implement a control on the basis of polarized spectral reflectance values, in particular for a detector (28) which measures unpolarized spectral reflectance values.

Methods and apparatus, including computer systems and program products, that relate to diversification of computer code. The methods feature a machine-implemented method that includes receiving input computer code, and automatically generating multiple versions of diversified computer code, where each version of the diversified computer code is distinct from but functionally equivalent to the input computer code. The input computer code can include source code or binary code and automatically generating multiple versions of diversified computer code can include automatically generating multiple versions of diversified source and/or binary code. Automatically generating diversified computer code can include applying multiple diversification operations.

A method in a computing device for identifying interfaces related to a service provider includes receiving a call identifier as an explicit parameter in a call or as an implicit parameter contained within input data to request a service provided by the service provider, the call identifier representing a version of the service.
摘要:
A method for correcting digitized image data in the prepress stage when using printing presses having a device-independent color profile in the main printing stage, having the following method steps: colorimetric measurement of a reference sheet and production of an image file in a device-independent color space, conversion of an image file belonging to the reference sheet in a device-dependent color space into a further image file in a device-independent color space using the device-independent color profile belonging to the printing press to be used, comparison of the two device-independent image files. performing alterations on the device-dependent image file associated with the reference sheet or alteration of the printing process in the selected printing press if tolerance limits are exceeded.
摘要:
Methods and apparatuses enable brokering the execution of an application. Rather than setting up a complete application execution environment including hardware and software, an execution broker enables execution of an application in a system that is generated or made available in response to a request to execute the application. Some or all components of the hardware and/or software can be virtualized through resources available in one or more backend systems. The request may include a configuration description of a hardware platform and a software environment on which to execute the application. In one embodiment, the configuration of the hardware and/or the software is derived (e.g., based on minimum system requirements and/or client preferences). In response to receiving the request, a hardware platform and a software environment based on the configuration description are generated, to generate the application execution environment for the requested application.
