Definitions

  • 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 color control strips can be measured on the running machine with so-called machine densitometers or off-line using, for example, an automatic scanning densitometer, whereby the control loop towards the inking units can be open (quality assessment) or closed (machine control) in both cases.
  • a representative example of a computer-controlled printing machine with a closed control loop can be found in US-PS Nos, among others. 4,200,932 and 3,835,777. In practice, it often happens, for example for reasons of format, that the use of a color control strip is not possible. In these cases, the quality assessment is usually still done visually.
  • a system has recently become known (see, for example, the published UK patent application 2 115 145), which enables a mechanical assessment of printed products even without color control strips.
  • the printed products are scanned photoelectrically over the entire image area, so the measurement is carried out “in the image”.
  • the measurement is carried out on the running printing press by means of a machine densitometer.
  • the sample values from the individual picture elements possibly after special preparation, are compared with the sample values of a reference printed product (O.K. sheet), which may have been prepared, and a quality decision "good” or "bad” is made on the basis of the comparison result according to certain criteria.
  • the decision criteria include the number of picture elements which differ from the corresponding picture elements of the reference by more than a certain degree of tolerance, the differences in the sampled values summed up over selected image areas to the corresponding sampled values of the reference and the differences between the sampled values summed up via certain scan tracks corresponding values of the reference.
  • 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, 1.72, 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 include 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 can e.g. a commercially available scanner ("scanner"), as used for litho films, or any other suitable scanner, for example according to US-PS Nos. 3 958 509 and 4 131 879 or EP publ. Nos. 69 572, 96 227 and 29 561, 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 e.g. after visual assessment for printed products which are found to be of satisfactory quality, so-called proof sheets or OK sheets.
  • This scanning device scans the pressure sheets or OK sheets in exactly the same way as the machine densitometer 120 the printed products and is therefore constructed 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 display devices are not absolutely necessary, these are only drawn to facilitate understanding. In the same way, 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 250 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 e.g. would be connected to computer 150 via cable 251 or 351. 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 printed on the running machine by means of the machine densitometer 120 (or also individual ones Sheets are scanned off-line on a separate scanning device, for example, the OK sheet scanner 320), and an actual remission value R. is determined for each printing ink and for each picture element E.
  • control variables (manipulated values) ST for influencing the ink guiding elements 111-114 of the printing press 100 can also be calculated and the ink guiding of the printing press can thus be regulated.
  • 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, display the area coverage 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 and device 172 the differences between remission target values R and actual remission values R.
  • 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 certain conditions, offset printing makes it possible to remission (change) an image element of the printed product for the individual printing inks from the area coverage of the image element in question in the respective printing plate (or the corresponding screen) Film) to predict.
  • These prerequisites include, on the one hand, knowledge of the characteristic of the printing press and the influence of full density on the change in remission in Dependency of the area coverage and on the other hand that the picture elements are sufficiently small to come to 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 as a function of the area coverage of the printing plates. The table values are obtained by measuring standardized color plates 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. 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 in the short time available cannot be recorded and processed with economically justifiable effort. In addition, significant 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.
  • a picture element E can be, for example, square with an area of approximately 1 cm 2 .
  • 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 subdivided into a larger number, for example 100 sub-elements SE, and the area coverage for each of these sub-elements is determined.
  • 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 about 0.25 to 25 mm 2, a practical example is about 1 mm 2 relative to a pixel size of about 1 c m 2.
  • each individual sub-element SE is determined by means of the plate scanner 220 in a manner known per se, for example by remission measurement integrally over the area of the sub-element or by means of television scanning or scanning using discrete photo sensor fields or the like.
  • a remission subset value RS is now calculated from the area coverage on the basis of the printing characteristic curve previously determined in tabular form, taking into account the overprinting (intermediate table values can be found by interpolation).
  • the individual remission subset values RS of each picture element E s then become the remission setpoint, for example by arithmetic averaging value R of the image element E in question, which is required for comparison with the corresponding remission actual values R. 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).
  • an average full-tone weight factor G e for the entire picture element E in question is formed, for example, by arithmetic averaging.
  • These mean full-tone weight factors G are now used to determine the weight with which a possible deviation of the actual remission value R. from the remission target value R of each individual picture element E should be included in the calculation of the quality measure Q or the control variables ST .
  • the average full tone weight factor G e for example, the standard deviation in the sense of a weight reduction with a large standard deviation can also be taken into account.
  • a sensory weight factor H (or sub-sensory weight factor HS e ) to each individual image element E (or possibly also to each sub-element SE), which represents a sensory-metrical assessment scale for deviations from the setpoint and actual values.
  • These sensory weight factors can be determined, for example, according to CIELAB (Comite International de l'Eclairage) from the sensory metrics L * , a * , b * defined there.
  • a quality measure Q is now calculated for each printing ink and displayed in a suitable manner on the basis of the deviations ⁇ e between the measured actual remission values R. i and the previously calculated remission setpoint values R.
  • This quality measure can be calculated, for example, in such a way that the deviations A e are weighted with the respectively assigned full tone and / or sensation weighting factor G 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 play a special role as surface areas.
  • the control variables ST are preferably determined individually for each individual printing zone by the deviations weighted by the full-tone weight factors G. ⁇ e of the actual remission values R i from the remission nominal values R s of the picture elements E are summed (integrated) over the entire respective printing 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 e.g. as described in US Pat. No. 3,185,088 used 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 a so-called OK sheet 0KB
  • OK sheet 0KB 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 and / or H assigned to the individual picture elements can be adopted from the earlier measurement of the printing plates P.
  • the densitometric measurement of the printed products D on the running machine can be carried out in a wide variety of ways, as long as it is ensured that the remission or remission change of each image element is recorded for each color. It is not absolutely necessary for each individual printed product D to be completely measured a sequential measurement of different image elements on successive printed products is sufficient. Furthermore, for example, 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.
