Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • a method for controlling a printing press in which the printed image carrier web printed after passing through a four-color printing device with four colors (C, M, Y, K) is scanned by a scanner for generating image signals is converted into color measurement values in a control device and then compared with target values. Adjustment signals resulting from this comparison then set color adjustment devices of the printing device to correct the print image and, if necessary, display on a monitor whether the correction can lead to the desired print image result at all.
  • DE-C2-44 31 270 discloses a method for measuring the color density of a print image grid point for controlling the color guidance of a printing press. With this method, too, the measured values are obtained from real proofs.
  • DE-A1-43 35 143 discloses a method and a device for converting color values, in which an image is processed using tables and the processed image can be output on a color monitor and a proof recorder.
  • the method for transporting color values is taken up, but the method does not take into account the color space of the substrate, which was selected by a graphic artist well in advance of printing, but which has a decisive influence on the printing process and the printing result compared to the layout on the monitor.
  • EP-A2-0 063 286 A2 describes a method for the representation of
  • CMYK colors cyan, magenta, yellow, black
  • RGB red, green, blue
  • EP-B1-0 255 128 describes a method for an instant camera.
  • EP-A3-0 392 814, DE-A1-197 24 171 and DE-C2-44 31 270 describe methods for color control in rotary machines.
  • US 5 212 546 describes a method for calibrating a DTP workflow. Here, a reference picture is taken and compared using the method or rather adapted to the circumstances.
  • US 5 606 432 discloses a method for simulating a halftone print on a monitor and for output as a simulation on a printer. This is a common proofing process.
  • the US 5 333 069 describes a calibration method for proofers, since some output devices work in RGB color space and others again in CMYK and thus due to the differently used colors, such as.
  • a neutral (white) background is assumed, which is very rarely the case in conventional printing.
  • the substrate is not taken into account here for display on the monitor either.
  • the method for determining the color appearance disclosed by DE-A1-197 01 967 ensures that certain color values can be embedded in an ICC profile and the database can thus be optimized. However, the color space of the substrate is not taken into account.
  • DE-A1-97 01 967 mentioned takes into account, among other things, the printing density and the latents of a printing ink, but only in connection with a raster print and according to the calculation basis of Neugebauer. However, no solution to a calculation in surface pressure is proposed here either.
  • the object is to create a method according to the preamble of claim 1, which enables the definition of various printing parameters in advance of the later, real printing and thereby avoids real proofs and their costs.
  • the basic idea of the invention is essentially to enable a color comparison in advance of the subsequent, real print on a monitor, since a red, green and blue (RGB) display on the monitor has different results than the conventional CMYK print, for example in offset -, gravure or screen printing, reproduces (the abbreviation CMYK stands for the basic colors cyan, magenta, yellow and the contrast color black). This is related, among other things, to the color emission (additive color mixing and subtractive color mixing).
  • the invention makes it possible to display different printing materials, such as different types of paper, plastics, textiles, wood, stone, metal or coatings, and their printing properties, which have been determined by printing, on the monitor, in order to achieve a preselection of the different printing processes, and at the same time to create a real representation on the monitor that simulates the later printed product.

  • a further, expedient development of the method provides that the types of printing material are recorded photographically and slides are created therefrom and that the slides are then scanned by means of a scanner and the digitized sample values are entered into the computer. Here they are available to the user to select substrate types for a print product on the computer
  • a conventional printing of a test form on a specific printing material carries out densitometric evaluation of the color image on the printing material to be simulated for the later ICC profile.
  • This evaluation can thus advantageously be used further.
  • the input keyboard and the monitor are used to carry out a visual color comparison of the monitor display with the conventional pressure, with the incorporation of the densitometric evaluation. A simple correction of the color image is therefore possible.
  • an ICC profile is created after the color matching and stored on a storage medium. You can always use these ICC profiles.
  • the ICC profile stored on the storage means can be integrated into the graphic color image and can be displayed on the monitor.
  • the user's database is optimally prepared for printing using the substrate-specific ICC profile.
  • a computer 1 is connected to a 21 " monitor 2 and an input keyboard 3. This monitor and this input keyboard are shown again at the bottom right of the figure.
  • Digitized data about the types of printing material and their printing properties are entered into the computer 1 in the following way:
  • the paper types a indicated by a box 4 are recorded photographically in accordance with arrow 5 in a conventional manner and created as slides b in box 6.
  • the slides b are scanned by means of a scanner 7, and the scanned values are digitized in accordance with arrow 8 and stored as paper image ac in box 9 and fed from there to computer 1 in accordance with arrow 10, in which they are stored.
  • This image document ac can be displayed on the monitor 2 using the input keyboard 3.
  • a box 11 symbolizes digital, graphic color image documents f according to printing processes and thus according to printing inks and their properties. Shafts according to the arrow 12 fed to the computer 1 and displayed together with the image documents ac on the monitor 3.
  • a specific representation ac + f on the monitor 2 can then be selected by means of the input keyboard 3 and used to represent a simulated pressure g on the monitor 3.
  • This simulated proof refers, for example, to a conventional offset printing on paper type a indicated by the arrow 13 and a printing press 14.
  • conventional pressure g a sitometric evaluation is carried out according to standard values from FOGRA.
  • Conventional pressure g and densitometric evaluation are indicated by a box 15.
  • the pressure g is required in order to be able to carry out a visual comparison on monitor 2.
  • the density range of the pressure g is measured with the aid of a densitometer, in order to be able to create a pressure characteristic curve, which in turn is required to create an ICC profile, as will be explained.
  • a color comparison can now be carried out in accordance with the arrow 16, the densitometric evaluation being incorporated and then an ICC profile S being produced on the selected paper a.
  • Color matching and ICC profile creation are indicated by a box 17.
  • a CD can be produced using a corresponding device 19, which embeds the substrate profiles in the existing ICC__ workflow.
  • an ICC profile i can also be integrated into a graphical color image document according to arrow 20 and displayed on monitor 2. The integration takes place by means of a programmed tool.
  • ICC profile is generally known in specialist circles.
  • the name ICC stands for the "international Color Consortium", a committee made up of representatives of leading hardware and Software vendors. This committee has drawn up a platform-independent ICC device profile format which contains the information about colorimetric characterization values
  • ICC profiles are independent of their creation program, so that they can be used on any ICC-compatible device.
  • a softproofing method S and a representation g simulated on monitor 2 are therefore created, as indicated by box 23, with which a selection of printing methods and their properties, printing colors and their properties and substrates and their properties are possible before the real proof.
