Definitions
- controllability of the inking unit with regard to the range of colors has disadvantages both in terms of the standard effort, as well as in terms of the resulting resulting complexity of the inking unit, as well as in terms of the desired Different color samples have no effect on subsequent ones Printed copies.
- inking systems e.g. B. in offset printing the anilox inking unit, that is Short inking unit for printing with low-viscosity printing inks, for example for the Newspaper printing, the ink more directly over an anilox roller and a few Bring the intermediate cylinder onto the printing form and thus considerably reduce it Show complexity with all the resulting benefits.
- inking units only allow a very limited regulation of the Color range.
- Each substrate now needs a specific one for a defined solid color density Color quantity, depending on surface roughness, absorbency, kick-off behavior and others.
- An inking unit that cannot be regulated in terms of ink quantity in connection with A binary printing form can therefore only have certain solid densities, depending on The type of substrate fluctuates, it should not be different depending on the substrate Anilox roller or a color of other pigment concentrations or viscosity be used.
- the object of the present invention is therefore to provide a method for varying the Color density of the full tone when printing within a rotary printing press develop that despite the constant color supply of the inking unit or the color-applying elements a control of the solid color density, or a Adjustment of the halftone values in the print allowed.
- the object is achieved by the measures of claim 1. That included the printing process used itself can preferably be lithographic offset, High pressure, flexographic or electrophotographic or electrographic Be pressure. However, the invention is not limited to these methods.
- the geometric tonal value increase in color transfer from the Note the printing form on the substrate.
- dot gain is based on the concept of area coverage. Area coverage is defined as the share of Area in a specific location that is covered with paint. This is measured either via optical-geometric measurement methods, which the pure measure geometric area coverage or by measuring the Transmission ratios of fully covered area (full tone) and the partially covered area (halftone), which is then the effective or optical Measure area coverage.
- the screen dot size (in a basic screen) is a decisive factor for the print quality. Lighter color nuances are usually represented in printing by rasterizing the three basic colors cyan, magenta and yellow together with black. The dot size is determined in the binary imaging of the printing form in accordance with the tonal values of the respective image information. During screening, bright image areas are broken down into small and dark image areas into larger screen dots (binary, area-variable image information). This applies to both a periodic autotype grid and a stochatic grid.
- the area coverage in% serves as image information.
- the halftone value can be in Percent area coverage are specified, i.e. 0% for white and 100% for Full surface. As is well known, the halftone tone value does not correspond to the print geometrical area coverage on the printing form, since both geometrical and optical effects also lead to a so-called dot gain.
- Tonal value increase in the sense meant here is the increase in Coverage from the printing form to the substrate.
- the dot gain splits into two parts, an optical and a geometric.
- the optical component is caused by light migration in the substrate (light trap) uncovered areas to the covered areas.
- the geometrical The part that just plays a role in the method according to the invention is represented by Squeezing effects in the ink transfer points from the printing form to the substrate or in electrophotography using toner clouds around the actual image areas evoked around. This effect reduces that on the printing form not covered area geometrically from the edges of the covered area.
- Controlling the color given is the basic grid of halftone dots for the area-variable image information, which determines the area coverage, a very fine, preferably compared to the basic grid by at least a factor of two finer micro grid is subordinate to the area coverage of the basic grid the set percentage is reduced.
- the printing form now takes according to the geometrically covered areas from the system providing the color Ink off - in offset these are the inking rollers of the inking unit - through which However, the microgrid does not appear on the printing substrate more.
- the dot gain results from the difference of the known Screen tone value for the printing form illustration and the measured Screen tone value in print.
- the dot gain as a deviation of the Screen tone value in print from the screen tone value of the printing form can be used for Imaging and micro grid backing can be used directly in a so-called Pressure characteristic curve are shown.
- This generation of characteristic curves and their Use in the printing process is from densitometric measuring technology for Printing presses are well known and are not discussed further here.
- Fig. 1 B shows schematically. It is of course possible in Area of the highlights according to FIG. 1 C) to dispense with a micro grid, or to set to 0% tonal value reduction. Also a smooth transition with a high one Reduction with large tonal values and little to no reduction in small tonal values are conceivable.
- the entire point structure must be in its transmission characteristics be characterized and compensated.
- Area lower optical density of a raster point and in particular also the Solid tone density must of course be used when determining a tone value curve be taken into account.
- the effective optical area coverage is then analogous to previous measurement, the ratio of remission of the grid area to Solid area, even if the printing form for both the solid and the halftone dot Can have holes.
- the above procedure is also based on stochastic grids and hybrid Grid transferable.
- the points are then essentially the same size a micro grid is highlighted. This happens in an extended version of the Then the procedure after checking the environment is not, or only to a lesser extent Extent when a point stands alone or a cluster does not have a certain size exceeds.
- the micro grid can also be stochastic both in connection with conventional as well as stochastic Screening.
- the method according to the invention for offset printing is preferably used an anilox inking unit used.
- the printing form preferably a thermal one imageable plate or sleeve without chemical aftertreatment, which is a very high edge sharpness and resolution is allowed in or outside the Printing machine with a resolution of z.
- the laser imagesetter writes with continuous steel.
- the basic grid is not modified for maximum color transfer, or set to 0% area coverage reduction.
- 25% in the covered areas i.e. the Area elements of the binary image information
- the Laser writing beam each two pixels (halftone dots) wide, i.e. e.g. switched on for 10 ⁇ m, then one pixel (halftone dot) i.e. for 5 ⁇ m switched off. In the adjacent writing line, one pixel is then offset, written the same pattern, so that each 5 ⁇ m insulated holes arise.
- Another embodiment can write beams larger than 10 microns use, but is not limited to this. Is in the writing direction of the Laser beam realizes a higher addressability than the spot diameter corresponds, the addressability grid in the scanning direction is narrower than transverse to Scanning direction. It can be used to create rectangular holes that are perpendicular to the Scanning direction lie (see Fig. 3 A)) up to the square hole (see Fig. 3 B) and C)) and rectangular hole in the scanning direction.
- the proportion of 20 ⁇ m points to 10 ⁇ m points can then still be an intermediate gradation can be created.
- Area of the higher Area coverage can be transferred with the same effective area coverage Color amount can be controlled via the average hole size. If the holes in the Medium is larger, more color is transferred than medium-sized ones but more numerous holes, because then the continuous solid areas are smaller.
- this can also be used for correcting tonal value characteristics in conventional inking units which can be regulated in zones or over a wide range.
- the full tone is not interspersed with holes and its effective density is reduced, but only the halftone dots according to a predetermined characteristic.
- it can be used to produce a printing press with a linear transfer characteristic by just compensating for the effective dot gain.
- Another alternative application is a local reduction in the full tone or Screen density, depending on predictable color transfer deviations from the target, e.g. Paint waste or stenciling. This is a compensation of Weaknesses in the paint application system possible, both independent of the subject can also be subject to subject.

Abstract
Description
Dies gilt sowohl für ein periodisches autotypisches Raster als auch ein stochatisches Raster.
In diesem Fall wird nicht der Vollton mit Löchern durchsetzt und in seiner effektiven Dichte reduziert, sondern nur die Rasterpunkte nach einer vorgegebenen Kennlinie. Beispielsweise kann damit eine Druckmaschine mit einer linearen Übertragungscharakteristik erzeugt werden, indem die effektive Tonwertzunahme gerade kompensiert wird.
