摘要:
An image is printed on a substrate by means of a computer driven printer using heat activated dyes, without activating the dyes during the process of printing onto the substrate. The dyes are subsequently activated by applying sufficient heat and pressure to the substrate to activate the dyes.

A printing system includes a printing apparatus and a computer. The printing apparatus and the computer each include a density setting section. The printing system further includes a data processing section, which is at least adapted to transfer printing density data for a predetermined printing object from the computer to the printing apparatus so as to set printing density on the printing apparatus and to transfer printing density data for a predetermined printing object from the printing apparatus to the computer in order to store the printing density data in a database. Since printing density can be set on either of the printing apparatus and the computer, for example, in a trial printing mode, printing density data are transferred from the database stored in the computer to the printing apparatus so as to set printing density on the printing apparatus, thereby enabling trial printing. When the printing density set on the printing apparatus is modified on the basis of the result of the trial printing, the modified printing density data are transferred to the computer to thereby update the database accordingly.

A method of determining the area coverages of a printing plate for controlling the quantities of ink in inking zones of a printing press, includes, to produce the plate from existing printed-sheet data, producing color-value printing data based upon a standard raster system, converting the printing data by a raster generator into rastered printing data, exposing the rastered printing data onto film material or a printing plate by an exposer, using various raster systems with different dot gains on the plate, in the raster generator, depending on the raster system used, applying an associated dot gain correction curve and a linearization correction curve to the color-value printing data, and supplying an area coverage calculation unit with coarse color-value image data derived from the color-value printing data, a dot gain correction curve for each raster system used, and correction location data describing in which areas of the plate which raster system is used.
摘要:
The invention concerns an assembly for printing on a substrate comprising: a camera for recording a reference pattern; a computer connected to said camera to store and modify, if required, data (N) concerning the reference pattern; and a printer whereof at least the print head is controlled by a printer file (FI) generated by the computer. The invention is characterised in that it comprises: means supporting and moving the substrate; means for analysing and comparing a pre-recorded pattern with a pattern located on the substrate, and for adapting or not the data (N) concerning the reference pattern as a result of the comparison; and means for generating a printer file (FI) based on the data whether or not modified.

A method for setting machine settings for a printing machine at a time selected from before and during printing of a printed product on a printing machine, includes providing for one of an operator of the printing press and a pressman to evaluate a printed result of a printed product produced in one of a production printing and a proof printing, and resetting the machine settings, if necessary; in dependence upon an enabling signal, storing prescribed input variables and machine settings, which define a print job, in a control system belonging to the printing machine; and applying the stored values for influencing future settings of the printing machine, even for other print jobs; a printing machine for performing the method; and a material for printing with the printing machine.
摘要:
A method of forming a pattern of a functional material on a substrate is disclosed. In accordance with the method, a first pattern of a first material is applied to the substrate and a second functional material is applied to the substrate and the first material. The first material, the second functional material, and the substrate interact to spontaneously form a second pattern of the second functional material on the substrate. The invention is directed to methods for spontaneous pattern formation of functional materials on substrates, and devices produced according to the methods of the invention. In particular, the methods of the invention provide a simple, inexpensive method for patterning a functional material on a substrate, with broad applicability to numerous devices.

An apparatus and method for storing rubber-covered cylinder sleeves for offset printing for rotary printing machines permits an identified rubber-covered cylinder sleeve to be found easily. The apparatus is equipped with an electronic memory device into which, for each rubber-covered cylinder sleeve, characteristic data can be entered and stored. As the rubber-covered cylinder sleeve is introduced into a storage, the characteristic data from the rubber-covered cylinder sleeve are read into the memory device, and the rubber-covered cylinder sleeve can be removed from the storage apparatus in accordance with predefined data.
