Abstract

A method of adapting a Lab setpoint color value of multicolored printed products, wherein a special color is replaced by process colors using an ICC color profile. A measurement point that is assigned to the replaced special color on the printed product is metrologically acquired using a color measuring system and a Lab actual color value of the measurement point is calculated. The ICC color profile or a standardized ICC color profile is used for computing the color composition of the Lab setpoint color value from the participating process colors. Changes of the layer thicknesses of the participating process colors are ascertained to achieve a predetermined Lab setpoint color value of the measurement point using a digital tool or a digital model. The participating process colors are adapted using the ascertained changes of their layer thicknesses.

Abstract

A method of operating a flexographic printing press having a printing cylinder carrying a sleeve with at least one flexographic printing forme or a flexographic printing cylinder, and an impression cylinder, includes adjusting contact pressure between the printing cylinder or the flexographic printing cylinder and the impression cylinder by motor. The adjustment is made in an automated way as a function of a dot density of the flexographic printing forme, i.e. of a location-dependent density of printing elevations on the flexographic printing forme or data computationally derived therefrom. A cost-efficient way of producing high-quality prints in an industrial flexographic printing process is thus provided. In addition, the method advantageously provides further automation of the printing process. A flexographic printing press, a flexographic printing press system, and a flexographic printing forme or sleeve for a flexographic printing forme are also provided.

Abstract

A method and device change printing plates on a cylinder. The method includes opening a first clamping device and releasing a leading edge of a first printing plate and opening a second clamping device and releasing a trailing edge of the first printing plate. The first and second clamping devices are both opened before a first rotation process of a cylinder. The cylinder is rotated during the first rotation process in a first direction to dismount the first printing plate from a circumferential surface of the cylinder. The cylinder is rotated in a second rotation process in an opposite second direction to mount a second printing plate replacing the first printing plate to the circumferential surface of the cylinder. Because the first clamping device and the second clamping device are both opened before the first rotation of the cylinder, the set-up period required for a printing plate change is reduced.

A method correctly mounts printing plates in a printing press. The method uses prepress software, a transport device, an identification device disposed on the transport device or on a printing plate, and a scanning device. The prepress software defines a sequence of print jobs to be processed by the printing press and sends data for making the printing plates for the print jobs defined in the processing sequence to a platesetter. The platesetter produces the corresponding printing plates. The produced printing plates are deposited on the transport device, the transport device is conveyed to the printing press, and the identification device of the transport device or of a printing plate is scanned by a scanning device at the printing press and the print jobs that have been identified in this way are compared to the print jobs which the prepress software has assigned to the printing press.

Abstract

A method of producing printed products uses at least one computer and at least one input device for controlling at least one machine for processing printing substrates. The input device receives technical and economic data of at least one print shop and the computer receives customer preferences relating to print jobs by using the input device. Based on the technical and economic data of the print shop, the computer calculates a simulation of possible print jobs producible in the print shop. The computer takes into account the results of the simulation and the customer preference inputs and generates matching offers for print jobs. The computer compares the generated offers with customer print jobs and, if a match is found between an offer and a customer's print job, the print job is processed by the machine for processing printing substrates.

Abstract

A method for compensating for position-dependent density fluctuations of print nozzles in any inkjet printer by a computer. The computer produces, for all substrates used, compensation profiles for the position-dependent density fluctuations over all print heads of the inkjet printer and applies the compensation profiles to compensate for the position-dependent density fluctuations in the inkjet printer. The computer determines in each case printer-specific or print head-specific influences and print substrate-specific influence factors with a generic reference print substrate, from which a reference compensation profile is produced which depends on the surface coverage and location. From this the computer produces a total compensation profile which is used to compensate for position-dependent density fluctuations.

Abstract

A method performs color control in a printing operation on a printing machine by use of a computer. The computer uses an input profile to transform print image data from a first color space to a device-independent color space, subsequently uses an output profile to transform the print image data into a second color space dependent on the printing machine. The computer compares measurement conditions of the used input profile and of the output profile to be generated, and, if there are differences between the respective measurement conditions, adapts the print image data in the device-independent color space to deviating measurement conditions of the output profile. The printing machine subsequently executes the printing operation using the print image data, and wherein UV light excitation is used for the measurement conditions of the output profile.

Abstract

A method compensates for position-dependent density fluctuations of print nozzles in an inkjet printing machine by use of a computer. The computer produces compensation profiles for the position-dependent density fluctuations over all the print heads for all print substrates used, calculates an mean profile from these, and applies the mean profile to compensate for the position-dependent density fluctuations in the inkjet printing machine. When one or more print heads of the inkjet printing machine are replaced, the computer calculates a new compensation profile for only one print substrate. The computer derives a new mean profile from this, and the computer calculates and applies the new mean profile using the old compensation profiles for the remaining print substrates.

Abstract

A method for reducing the effect of defective printing nozzles in a multicolor printing process on an inkjet printing machine. A computer creates a color transformation table that, for every process color of the inkjet printing machine, includes a replacement combination of the respective other process colors with a minimum color distance to the process color in question. The color transformation table is used to compensate for a defective printing nozzle. The color transformation table is created by printing and measuring a test chart with all process colors and interpolated by the computer. The color transformation table is then optimized to avoid undesired transitions between supporting points of the color transformation table and the resultant color transformation table accordingly contains process color combinations with minimum sensitivity to defective printing nozzles and the optimized table is used to carry out the multicolor printing operation on the inkjet printing machine.

Abstract

A method for detecting and compensating for defective print heads in an inkjet printing machine uses a computer to analyze printing nozzle test charts and/or area coverage elements to obtain characteristic values of individual printing nozzles in a print head, to calculate the failure probabilities of these printing nozzles on the basis of thresholds, and to compensate for a printing nozzle that exceeds a specified failure probability. The computer uses the individual failure probabilities of the individual printing nozzles in a print head to calculate the failure probability of the print head and initiates compensation measures as a function of the calculation. The thresholds correspond to a multi-dimensional characteristic value threshold based on which the computer calculates the failure probability of a printing nozzle by using an algorithm including kernel density estimation through a multidimensional distribution function.

Abstract

A method for inkjet printing machine color control includes color transformation of print data from first color space to process color space in a first stage using a computer transforming print data from the first to an intermediate color space while keeping special colors, and a second stage transforming corrected print data including special colors from intermediate to process color space. The computer uses print data corrected after the first stage as second stage starting values. Print data transformed into the process color space are printed. First color space corresponds to CMYK, flexographic printing or RGB color space with special colors, intermediate color space corresponds to CMYK color space with special colors, process color space corresponds to CMYK color space with additional process colors. The computer corrects CMY, not K print data or special not transformed colors, when correcting print data in the intermediate color space after the first stage.

Abstract

A method prints and dries a substrate where ink containing water and pigment is printed onto the substrate in an inkjet printing process. The substrate has an initial moisture content and absorbs at least water of the ink, causing the moisture content of the substrate to rise. Radiation selectively acting on the water molecules is applied in a first drying step and then radiation selectively acting on the pigment is applied in a second drying step in such a way that after completion of the two drying steps, the water of the applied ink has essentially completely evaporated and the substrate has essentially reattained its initial moisture content. In this manner optimum drying of substrates to which ink has been applied occurs.

Abstract

A method for printing on the surface of an object uses a print head generating ink drops to print at least a first swath and subsequently a second swath of ink onto the surface in such a way that the swaths are mutually adjacent and overlap in a strip. The first and second swaths are printed as solid areas and the swaths are XY stitched in the strip. In the strip, at least one of the two swaths is additionally stitched by using a function of an ink amount profile in a Y direction. High-quality or even highest-quality printed products can therefore be produced, in particular avoiding defects that are visible to the human eye in a region of overlap or a strip between swaths that are printed next to one another.

Abstract

A method for detecting and compensating defective printing nozzles in an inkjet printing machine includes periodically printing at least one printing nozzle test chart having horizontal rows of equidistant vertical lines underneath one another, with only nozzles contributing to the test chart in every row corresponding to horizontal rows, and printing an area coverage element geometrically associated with the test chart. Both elements are recorded by an image sensor and evaluated by a computer. The computer identifies print defects by evaluating the area coverage element and allocates the defects to defective nozzles. The computer evaluates the test chart based on thresholds to detect defective nozzles and compensate detected defective nozzles. The computer compares the detected defective nozzles from the area coverage element and the test chart to identify detected defective nozzles causing defects in only one element and calculates the thresholds based thereon to minimize the detected defective nozzles.

Abstract

A method for image inspection on printed products in a printing material processing machine. Printed products are recorded and digitizing and the recorded images are compared with a digital reference image to find image areas with distorted regions. Suitable rectification factors are calculated and the digital reference image is rectified with suitable rectification factors for the distorted image areas. The modified digital reference image is then compared to images recorded during the production run. If deviations are found, the printed products are found defective and removed. The computer also identifies image areas in the reference image that do not have enough edges for calculating suitable rectification factors and inserts anchors into the image areas. The anchors are printed, recorded and digitized, as they become part of the recorded digital printed image. In that case, the computer calculates the local rectification factors by way of the anchors.

Abstract

A method and device change printing plates on a cylinder. The method includes opening a first clamping device and releasing a leading edge of a first printing plate and opening a second clamping device and releasing a trailing edge of the first printing plate. The first and second clamping devices are both opened before a first rotation process of a cylinder. The cylinder is rotated during the first rotation process in a first direction to dismount the first printing plate from a circumferential surface of the cylinder. The cylinder is rotated in a second rotation process in an opposite second direction to mount a second printing plate replacing the first printing plate to the circumferential surface of the cylinder. Because the first clamping device and the second clamping device are both opened before the first rotation of the cylinder, the set-up period required for a printing plate change is reduced.

Abstract

A method for compensating for defective printing nozzles in an inkjet printing machine by way of a computer. Defective printing nozzles are compensated for by an increased ink drop volume of neighboring printing nozzles and the real positions of the print dots of all printing nozzles are determined and, to compensate for a printing nozzle failure, the required ink drop volumes of the respective neighboring printing nozzles are calculated for every printing nozzle as a function of the real positions of the print dots of the respective neighboring printing nozzles. In addition to increased ink drop volumes of the respective neighboring printing nozzles, reduced ink drop volumes are calculated for the respective next but one printing nozzles and all ink drop volumes are calculated based on the print dots of the respective printing nozzles.

Abstract

nd mode of printing a reduced-color second print job at a second conveying speed greater than the first conveying speed and at the same print resolution using the n inks. The printing speed and thus the number of prints produced per unit of time in a machine can therefore advantageously be increased.
