Definitions
- the invention relates to a print control strip for checking and controlling the printing process with individual color fields of different color and structure which are arranged in a row and which are divided according to the color zones of the ink fountain of a printing press.
- Print control strips are a well-known means of assessing and controlling the print quality and the preliminary stage of printing in modern printing machines. For this purpose, they have different numbers and arrangements for each individual color to be printed, fields which are to be assessed visually, so-called signal fields and measuring fields. In addition, multicolored fields are usually specified for certain controls.
- a print control strip usually contains the following fields:
- fields with microlines and microdots can be provided for specific purposes.
- Densitometers have been used almost without exception as measuring devices for measuring the individual fields of the pressure control strip, and other color measuring devices have only been used in special cases.
- Print control strips of this type which are used for the control and / or regulation of the coloring, are matched in their division to the ink zone distances of the printing press in question.
- the control and / or measuring fields for assessing the other quality criteria are less common on the print control strips.
- the "full tone control" is particularly advantageous because only the saturation as a measure of the color layer thickness is included in the measured value DV as a variable. The assignment of the measured value within the printing process is therefore clear.
- a disadvantage of the pure solid tone control has proven that, despite the matching solid ink density, the print and the print template do not have to match visually, both in the measuring field and in the image. There are a number of reasons for this, e.g. different pigments or dyes, different substrates and the like.
- variable "density raster DR" also includes variables, that are independent of the coloring itself. Worth mentioning here are the pressure between the plate and blanket cylinders, the printing substrate, the blanket, the dampening solution and the dampening solution guide, the pressure plate, and pushing and duplicating.
- Variables derived from solid density DV and screen density DR can also be used for color control.
- Measuring strips are used in both the regulation according to DR and the regulation according to the halftone tone value F, in which single-color dot matrix fields for all printing inks are present in each color zone.
- the grid fields predominate here. All other fields are less common.
- the zonal color compensation that takes place due to the lateral rubbing is used.
- the lateral rub is equal to the width of a color zone plus a small overflow.
- EP-A 0 255 924 relates to a method and a device for influencing the color appearance of a color area in a printing original and discloses in FIGS. 14 and 15 a print control strip in which a screen composed of the colored basic partial colors in each zone Control field is measurable and in every second or third zone a screen or solid color field is also black is measurable. This document therefore only reveals individual control fields. Since this document has not been previously published, it is of no importance for the question of inventive step.
- the further known (DE-A 36 04 222 shows a set of individual color strips to achieve a uniform printing result, which makes it possible to now also print combination measurement fields which result from the overprinting of single color measurement fields.
- the measurement values obtained from these combination measurement fields are mainly used to control the inking units
- the individual color fields are lined up with different colors and structures and are sized according to the color zones of the respective ink fountain of the printing press.
- the object of the invention is to provide a pressure control strip which allows the optional use of both the full tone control / regulation and the screen tone control / regulation.
- the color control / regulation is to be made possible in an optimal manner according to sizes derived from solid full tone and density grid of single and / or multicolored grid fields.
- the print control strip has, according to claim 1, zonal alternating single-color solid color fields for each printing color and single-color grid fields for each printing color.
- the main advantage of a print control strip constructed in this way is that the printer has the choice of using one or the other control strategy depending on the subject. He can e.g. also carry out the setup and adjustment according to standard solid ink densities and regulate the production to constant adjustment sheet screen densities or screen tone values. Conversely, it also makes sense if, for example, a "replacement proof” such as "Cromalin” or "Matchprint” is available as a print template.
- the printer is therefore not forced to buy, store and manage multiple types of print control strips, resulting in lower costs. Neither does he have to decide before the printing plate copy which control method should be used in printing.
- the solution to claim 2 offers the further advantage that the additional multicolored grid fields in the print control strip are optimally suitable for both densitometric and colorimetric measurement.
- the multicolored grid fields are integrated in the print control strips with the same frequency as the single-color solid and grid fields - i.e. also two-zone.
- Claim 3 identifies an embodiment variant with single-color solid-color fields and multi-colored grid fields in a two-zone structure.
- a surface coverage composition of the individual colors involved is proposed according to the invention for the metrological control of multicolored grid fields, which, as a sum of all one, two and possibly three and four-color partial areas, result in approximately the same degree of area coverage as the single color grid fields used in the control strip.
- An embodiment of the invention is shown schematically in the drawing for some color zones.
- the print control strip 1 is provided with individual color fields 2 of different colors and structures which are lined up in a row. Border lines 3, which correspond to the pressure control strips 1, are attached for explanation divide the ink zones of the ink fountain of a printing press.
- the individual color zones are continuously identified by numbers 4.
- the print control strip is alternately provided with single-color solid-color fields 5 for each printing color and with single-color grid fields 6 for each printing color.
- the monochrome grid fields 6 are advantageously designed as a dot grid. Both the solid tone fields 5 and the grid fields 6 are arranged alternately over the length of the print control strip 1.
- every second color zone between the grid fields 6 is provided with multicolored dot grid fields 7 in the region of the boundary lines 3.
- each dot matrix 7 is almost identical to the covered areas of dot matrix 6 and preferably in the three-quarter tone range, it being immaterial whether a dot grid with 75% halftone tone value of one color or the dot grid 7 shown in the exemplary embodiment as a three-color grid, in which cyan has 40%, magenta 32% and yellow also 32%.
- the necessary area coverage of the individual color separations as well as all partial areas resulting from the combined printing can be determined according to the "Neugebauer equation". Is z. If, for example, an average practical tonal value increase in printing of 15% at 40% screen tone value is taken into account, the following screen areas with identical coverage would result in printing.
- Single color grids 75% screen value Two-color grids 2 ⁇ 48% screen value
- the proportion of paper white is approx. 13% in all cases
- Multi-color grid fields designed in this way also have the advantage that they do not overestimate color shifts due to changes in the ink acceptance behavior.
