Definitions

  • the invention relates to a method and a device for regulating the ink flow in an offset printing machine according to the preamble of claims 1 and 16, as well as an offset printing machine equipped with a corresponding device according to the preamble of claim 20.
  • the assessment of the print quality and regulation of the color routing is usually carried out with the help of standardized color control strips. These printed control strips are evaluated densitometrically and the color values of the printing press are then adjusted accordingly.
  • the measurement of the color control strips can be done on the running machine with so-called machine densitometers or off-line by means of e.g. B. an automatic scanning densitometer, the control loop to the inking units in both cases open (quality assessment) or closed (machine control).
  • a representative example of a computer controlled printing machine with a closed control loop is u. a. in U.S. Patent Nos. 4,200,932 and 3,835,777.
  • the invention is now intended to remedy this situation and to show a possibility of how the color guidance in a printing press can be regulated automatically without the use of a color control strip during the start-up phase of the printing press to regulate the pressure and, if appropriate, during the production run.
  • the overall system shown in FIG. 1 comprises a four-color offset printing machine 100, three photoelectric scanning devices 120, 220 and 320, three computers 150, 250 and 350 and four optical display devices 171, 172, 270 and 370.
  • the offset printing press 100 is of conventional design, its ink guide elements 111-114 (ink fountain keys, etc.) are only indicated symbolically in the drawing.
  • the scanner 120 is a so-called machine densitometer built into the printing press 100 with four scanning channels 121-124 for each printing ink. With this scanning device, printed products can be measured densitometrically on the running printing press. Examples of suitable machine densitometers are u. a. in U.S. Patent Nos. 2 968 988, 3 376-426, 3 835 777, 3 890 048 and 4 003 660. In the following, the scanning device 120 is briefly referred to as “machine densitometer 120”.
  • the scanning device 220 is used for the photoelectric measurement of printing plates or raster films on which these are based.
  • the scanner 220 may e.g. B. a commercially available scanner ("scanner"), such as is used for litho films, or any other suitable scanner, for example according to US-A Nos. 4131 879 and 3 958 509 or Europ. Patent applications Publ. Nos. 69 572, 96 227 (Art. 54 (3) EPC) and 29561, which allows printing plates or raster films to be photoelectrically scanned with the resolution specified below.
  • the scanning device 220 is referred to below, regardless of its type and the object actually scanned, as a "plate scanner 220.
  • the scanner 320 is used for photoelectric measurement of z. B. after visual assessment for qualitatively satisfactory printed products, so-called proof sheets or OK sheets.
  • OK sheet scanner 320 This scanner scans the pressure or OK sheets in exactly the same way as the machine densitometer 120 Printed products and is therefore structured accordingly.
  • OK sheets can be scanned directly and even advantageously directly from the machine densitometer 120 in the printing press 100.
  • this scanning device referred to below as “OK sheet scanner 320”, is shown as a separate element.
  • the four optical display devices 171, 172, 270 and 370 are preferably color television monitors, which allow a visual representation of the measured values recorded by the scanning devices or the data determined therefrom by the computers.
  • four separate display devices are not absolutely necessary, these are only drawn for ease of understanding.
  • the system could also have only a single computer instead of three, which would then have to operate all of the connected scanning devices, display devices, etc.
  • the plate scanner 220 with its computer 350 and its display device 270 and the OK sheet scanner 320 with its computer 350 and its display device 370 can also form independent units, which then, for. B. would be connected via cable 251 or 351 to the computer 150. All of these possibilities are indicated in Fig. 1 by the dashed frames. They are completely irrelevant to the invention and the invention is in no way limited to them.
  • the printed products D are scanned photoelectrically on the running machine by means of the machine densitometer 120 (or also individual sheets off-line on a separate scanning device, for example the OK sheet scanner 320) and for each printing ink and for each picture element E.
  • Actual remission value R certainly.
  • the individual remission target values R s and the corresponding remission actual values R are compared with one another and control variables (manipulated values) ST for influencing the ink guide members 111-114 of the printing press 100 are calculated from the comparison results, and the ink guide of the printing press is thus regulated.
  • control variables (manipulated values) ST for influencing the ink guide members 111-114 of the printing press 100 are calculated from the comparison results, and the ink guide of the printing press is thus regulated.
  • the formation (and suitable display) of a quality measure is also possible in addition to the calculation of tax parameters for the color management.
  • the display devices 270, 171, 172 and 370 can serve to display the sample values or the values calculated therefrom.
  • Device 270 can, for example, cover the area or the brightness distribution of the individual printing plates P determined therefrom, device 370 the brightness distribution of the OK sheets, device 171 the remission target values R s and device 172 the differences between remission target values R s and remission actual values R ; Show.
  • the display devices can also be used to display all possible other data of interest.
  • the method according to the invention is thus based on the knowledge that under offset printing it is possible under certain conditions to determine the remission setpoint of a picture element of the printed product for the individual printing inks from the area coverage of the picture element in question in the respective printing plate (or the corresponding raster film ) to predict.
  • These requirements include a. on the one hand, the knowledge of the characteristic of the printing press and the influence of the solid color density on the change in reflectance depending on the area coverage, and on the other hand that the picture elements are sufficiently small to provide meaningful results.
  • the printing characteristic which takes into account all influences such as paper quality, printing ink, dot gain, ink acceptance, overprinting, wet-on-wet printing, etc., can be determined empirically relatively easily.
  • Tables are created for the reflectance of the printed product as a function of the area coverage of the printing plates. The table values are obtained by measuring standardized color tables that were printed on the respective printing press under representative conditions. For the measurement of these color charts, that scanner is preferably used with which the printed products are later also measured during operation, in the present case the machine densitometer 120.
  • the influence of the solid tone density on the remission change due to the dot gain can also be recorded using tables.
  • the above-mentioned color charts are used under appropriate printing conditions, i.e. H. printed with varying solid density of all printing inks.
  • the picture elements E In order to achieve the highest possible accuracy, the picture elements E must be chosen to be as small as possible. A natural lower limit is given by the grid fineness (e.g. 60 lines per cm). In practice, however, this lower limit cannot be reached for technical and, above all, economic reasons. This applies above all to the measurement of the printed products D on the running machine, since the amount of data that arises under the usual sheet formats under these circumstances is part of the short time available socially justifiable effort cannot be recorded and processed. In addition, considerable positioning difficulties would arise.
  • Image elements E of approximately 25 to 400 mm 2 in area are acceptable for remission measurements on the running printing press. Practically, a picture element E z. B. be square with about 1 cm 2 area. With image elements E of this size, however, the predetermination of the remissions, taking into account the overprinting on the basis of the surface coverage of the printing plate, becomes too imprecise.
  • each individual element E of the printing plates P (or the raster films on which they are based) is therefore divided into a larger number, e.g. B. divides 100 sub-elements SE and determines the area coverage for each of these sub-elements.
  • the determination of the area coverage for the image elements of the printing plates is therefore carried out with a higher resolution than the remission determination of the image elements of the printed products.
  • the size of the sub-elements SE can be approximately 0.25 to 25 mm 2 , a practical example is approximately 1 mm 2 based on a picture element size of approximately 1 cm 2 .
  • each individual sub-element SE is determined by means of the plate scanner 220 in a manner known per se, e.g. B. by remission measurement integrally over the area of the sub-element or by means of television scanning or scanning by means of discrete photosensor-feider or the like.
  • the area coverage is now based on the printing characteristic curve previously determined in tabular form, taking into account the overprinting a remission subset RS S is calculated (intermediate table values can be found by interpolation). From the individual remission subsets RS s of each picture element E is then by z. B. arithmetic averaging of the remission setpoint R s of the image element E in question, which is required for comparison with the corresponding remission actual values R i of the printed products D.
  • each sub-element SE is assigned a sub-full weight factor GS e that takes this influence into account.
  • These weight factors contain the required change in full tone (change in layer thickness) for each printing ink for a desired change in reflectance, taking into account the overprint and the local area coverage.
  • the weighting factors can be determined from tables for the full tone change as a function of the reflectance change. These tables can be determined from the table values for the reflectance as a function of the solid density (see influence of solid density).
  • each individual image element E or possibly also each sub-element SE
  • a sensation weight factor H (or sub-sensibility weight factor HS e ), which represents a sensation-based assessment scale for the setpoint-actual value deviations.
  • sensation weight factors can e.g. B. according to CIE-LAB (Comite International de l'Eclairage) from the defined sensory metrics L * , a * , b * .
  • a quality measure Q is now calculated for each printing ink on the basis of the deviations ⁇ e between the measured actual remission values R i and the pre-calculated remission setpoint values R s and is displayed in a suitable manner.
  • This quality measure can be calculated, for example, in such a way that the deviations ⁇ e are weighted with the respectively assigned full tone and / or sensation weighting factor G e or H, and added (integrated) over one or more selected surface areas of the printed product.
  • the surface areas can be adapted to the respective printed product. It is also possible to achieve several quality measures in this way.
  • the print zones Z (FIG. 2) specified by the printing press form a special role as surface areas.
  • the control variables ST are preferably determined individually for each individual printing zone by the deviations ⁇ e of the actual remission values R i weighted by the full tone weight factors G e from the remission target values R s of the picture elements E be summed (integrated) over the entire respective pressure zone Z.
  • the deviations ⁇ e of the actual remission values R i weighted by the full tone weight factors G e from the remission target values R s of the picture elements E be summed (integrated) over the entire respective pressure zone Z.
  • other evaluation and calculation methods are also possible here.
  • the area coverage determined by the plate scanner 220 can be integrated via the individual pressure zones Z and z. B. as described in US-PS-3185088 for presetting the color guide members.
  • the remission target values R i of the individual image elements E are calculated in advance on the basis of the area coverage of the corresponding image elements of the individual printing plates P or, if the measurements on these cannot be carried out for any reason, on the corresponding raster films, on the basis of which the printing plates were made.
  • a printed product that is found to be good can also be used as a basis for comparison. This would then no longer need to be scanned with the same resolution as the printing plates P, since only the remissions in the individual picture elements are of interest. These remissions can be determined either using the OK sheet scanner 320, or else using the plate scanner 220, if they are not already stored.
  • the weight factors G e and / or H e assigned to the individual image elements can be taken from the previous measurement of the printing plates P.
  • the densitometric measurement of the printed products D on the running machine can take place in many different ways, as long as it is ensured that the remission or remission change of each picture element is recorded for each color. It is not absolutely necessary for each individual printed product D to be measured completely, but a sequential measurement of different image elements on successive printed products is also sufficient. Furthermore, e.g. B. each individual color can be measured according to the respective inking unit or the remissions in the individual printing inks can be determined together on the finished printed product. A double measurement before and after each individual inking unit is particularly expedient, since in this way the influence of the respective color can be recorded particularly precisely.
