Definitions

  • the invention relates to the polygraphy and relates in particular a printing process called Orloff réelle is known and mainly for applying a protective pattern in the printing of value documents, in particular of Money sign, is applied.
  • the Orloff multi-color printing process is based on dyeing a collective printing form with the help of color stencils, wherein the collective printing form and the color stencils respectively a form cylinder and stencil rollers are arranged.
  • the drive of the stencil rollers from the forme cylinder takes place by means of a toothed gear.
  • Such a transmission ensured a fixed position of the templates with respect to the collective printing form, which position during the printing process is maintained.
  • An Orloff multicolor image is created by creating a continuously colored line formed with color transition.
  • the coloring of their various sections in appropriate Colors understood.
  • all color templates cover when they are laid on the collective printing the total area of the picturesque Field of the collective printing form completely, without that different individual color surfaces are stacked.
  • a template creates a clay plate in its construction with one hundred percent filling of the printing (ink-transferring) Surface.
  • the configuration of such surfaces is the pattern of the multi-color image to be displayed certainly.
  • the closest analogue solution was the one in the Application EP 0092887 A1 disclosed method of indirect and direct Orloff multicolor printing adopted Coloring the collective printing plate of a forme cylinder with the help of of stencil rollers whose color stencils comprise clay plates different configuration are.
  • the location of the templates is with respect to the collective printing form by that of the forme cylinder taking place gear drive of the stencil rollers fixed so that in this way during the printing process the Possibility of shifting the stencil rollers relative to the forme cylinder in both the axial and in the circumferential direction is excluded.
  • the main disadvantage of the existing method is that Lack of a mixing zone between two sections of different Colors in the indirect Orloff réelle and a small one Length of this zone (insufficient for the achievement of a Mixed color) in direct Orloff printing, which does not allow thereby the color gamma and the color wealth of the continuous colored line and therefore of the Orloff pattern itself enlarge.
  • the object of the inventively proposed Orloff multi-color printing process is, the quality of products, namely the color richness and the color gamma of the colored ones Line, and consequently the safety of value documents against any counterfeiting.
  • the task consists in enabling the formation of a Mixing zone between two sections of different colors the Orloffmusters and the generation of an iris effect in the limits of complete capture of the image in the Circumferential direction.
  • the stated object is in the inventive Orloff multi-color printing process solved in the coloring of the Collective printing form of a forme cylinder with the help of this Template rollers connected by a toothed gear consists, according to the invention, the coloring of the collective printing plate of the forme cylinder with the aid of stencil rollers is achieved by giving it a cyclical reciprocating forced movement in the axial and circumferential directions relative to the forme cylinder (return pulsation) is issued without the gear drive the same of the disturbing the latter, the size of the reciprocating Movement of stencil rollers in a range of Values between 0.2 and 4.0 mm, while the ratios between the number of retrograde movements and the Speed of the stencil cylinder are irrational numbers, which are in the range of 2 to 10.
  • the proposed method also provides for the installation of a additional storing stencil roller with forced movement within sizes that are the specified motion quantities correspond.
  • the said roller provides a tone plate according to the format of the pictorial field of the collective printing form and picks up or transfers the multicolor image during her Contact with the blankets of a collection rubber cylinder.
  • the border zone of the color template is predominantly through Introduction of a decreasing after the filling surface, continuous or stepped grid scale, whose Linear dimensions and gradation curves the length of the zone and determine the continuity of the color transition and the as Point or linear scale is formed, wherein the Rasterliniatur the mentioned scale in a range of values between 8 and 40 lin / cm.
  • the gradation characteristic of the stepped Raster scale the filling surfaces of the fields of the grid cell of 80, 60, 40 and 20%.
  • the continuously colored line is using a grid scale a fill area of the fields of the grid cell of 10, 40 and 80% used.
  • a technical result in the use of the invention can be achieved, is the creation of new ones artistic and technological possibilities of construction the actual multicolor Orloff pattern, since the production a zone of continuous color transition in the protective pattern it allows an iris effect within the limits of the complete Capture of the image in the circumferential direction too produce.
  • the iris zones of the color transition increase the total Rich in colors of the pattern thanks to a complementary color and thanks to tints without limiting their orientation about the extent and length of such zones.
  • Fig. 1 the principles of forming a zone the steady mixture of two colors to form a Complementary color illustrated.
  • the stencil rollers are when coloring the collective printing plate a forme cylinder the possibility of a permanent cyclic reciprocating forced motion (M) relative given to the forme cylinder in the axial and circumferential directions, without that of the forme cylinder successful gear drive is disturbed.
  • M permanent cyclic reciprocating forced motion
  • Research has shown that Production of a mixing zone with at least one complementary color the size of this movement of the stencil roller in a range of values between 0.2 and 4.0 mm, which is a displacement of the template relative to the central location in the limits of 0.1 to 2.0 mm in both directions.
  • One of the possible variants of the forced movement of Stencil paint rollers can be the use of a cam gear be.
  • the procedure also sees an additional transmission the colors by introducing an additional storing Forced roller stencil roller within the above given sizes, which is a uniform mixture ensures the colors in the zone of their steady transition.
  • the saving template represents a clay plate representing the format (size) of the picturesque field is equal to the area of the collective printing form.
  • the saving Stencil roller has no inking and picks up or transmits the multi-color image during their contact with the blankets of the collection rubber cylinder.
  • the straight Orloff multi-color printing depends on the incorporation of a storing Forced roller stencil roller with the installation an additional template - the clay plate - as a result the arrangement of the collective printing plate and the color stencils one and the same form cylinder together.
  • the color stencil In the construction of the color stencil is in its border zone introduced a grid scale, their density by different Fill area of the grid cell is specified. With respect to the boundary of the template, this area decreases, where it forms a value sequence of 100 to 0%.
  • the grid scale itself can be stepped or continuously decreasing. The dimensions and characteristics of this grid scale are in the formation and formation of the zone of continuous color mixing in the continuously colored line.
  • the raster line of such a scale lies in one Range of values between 8 and 40 lin / cm.
  • the width of the Grid transitions - VAR from 0 to 50 mm.
  • the length of the zone of a continuous color transition becomes determined by the total size of the grid scale and is located in a value range of 1 to 25 mm and above.
  • the real one Continuity of the color transition in this zone depends from the gradation characteristics of the raster scale. These requirements corresponds e.g. a five-field scale with a Fill area of the fields of 80, 60, 40 and 20%.
  • a raster scale for example with a fill-in area of 10, 40, 80% allows, at least three optical densities within the boundaries of a primary color of to obtain multicolored continuously colored line.
  • the different optical density of the line by reducing the thickness of the paint layer due to this a change of the fill area of the raster scale of generated color template.
  • the continuity of color mixing and the disclosure of Zone with the complementary color in the continuously colored Line does not just depend on the color characteristics of the Colors, but also on the choice of viscosity grades of the basic printing inks forming this zone.
  • the selection the viscosity indexes of the printing inks is in one range of values between 2 and 12.5 Pa ⁇ s (20 and 125 poise).
  • For example are the values of the viscosity of two inks, the form the zone of a continuous color transition for which indirect Orloff pressure equal to 7 and 8 Pa ⁇ s (70 and 80 poise).
  • the zone becomes steady Color mixing in the continuously colored line through the forced movement of the collecting rollers according to claim 1 and by the installation of an additional, designed as a clay plate Template and a storing collecting roller with forced movement achieved according to claim 2, with the proviso that the Claims of claims 3, 4 are met.
  • the fill area of these zones in the raster scales of blue and red stencils Color forms the following row accordingly: 3a - 80% + 20%, 3b - 40% + 40%, 3c - 20% + 80%.
  • the continuous zone of the color transition (N) between the blue and the red base color can in the traditional methods of indirect and direct Orloff multi-color printing can not be obtained.
  • the iris effect in the pattern is within the full detection of the orientation directions on the circumference educated. In this way, this zone depends on the steady Color transition in the continuous colored line not from the orientation of the same with respect to the axis of the forme cylinder of the printing press.
