Definitions

  • the invention relates to and relates to printing especially a printing process called Orloff réelle is known and mainly for applying a protective pattern when printing value documents, in particular from Money sign, is applied.
  • the Orloff multi-color printing process is based on coloring a collective printing form with the help of color templates, the collective printing form and the color stencils each on a forme cylinder and be arranged on stencil rollers.
  • the drive of the stencil rollers from the forme cylinder takes place by means of a toothed gear.
  • Such a gear ensures a fixed position of the templates with respect to the collective printing form, what position during the printing process is maintained.
  • An Orloff multicolor image is created by creating a continuously colored line with color transition formed.
  • the boundary of the Transition of a line segment of one color into one Line section of the other color due to the lack of mixing zones of these colors in indirect print and by existence a minimal mixing zone of colors in the direct Orlofftik.
  • all color stencils cover when they are placed on the collective printing form the total area of the painterly Field of the collective printing form completely without different individual color areas are placed on top of each other.
  • a stencil provides a clay plate in its structure with 100 percent filling of the printing (color transferring) Surface.
  • the configuration of such surfaces is from the pattern of the multicolor image to be reproduced certainly.
  • the main disadvantage of the existing process is that Absence of a mixing zone between two different sections Colors in indirect print and a slight one Length of this zone (insufficient to achieve a Mixed color) in direct print, which does not allow thereby the color gamma and richness of colors of the continuously colored line and therefore the Orloff pattern itself enlarge.
  • the object of the proposed Orloff multi-color printing method is, the quality of products, namely the richness of color and the color gamma of the colored ones Line, improve and consequently security of value documents against any counterfeiting. More specifically the task is to enable the formation of a Mixing zone between two sections of different colors of the Orloff pattern and the generation of an iris effect in the limits of full capture of the image in the Circumferential direction.
  • the task is in the invention Orloff multi-color printing process solved that in the coloring of the Collective printing form of a forme cylinder with the help of with this stencil rollers connected by means of a toothed gear there, according to the invention the coloring of the printing form the forme cylinder with the help of template rollers is achieved in that this is a cyclical back and forth forced movement in the axial and circumferential directions relative to the forme cylinder (return pulsation) is issued without the same gear drive from that to disrupt the latter, the size of the reciprocating Movement of the stencil rollers in a range of Values are between 0.2 and 4.0 mm, while the ratios between the number of retrograde movements and the Speed of the stencil cylinders are irrational numbers, which are in the range of 2 to 10.
  • the proposed method also includes the installation of a additional storing stencil roller with forced movement within sizes that match the specified movement sizes correspond.
  • the roller mentioned is a clay plate according to the format of the painterly field of the collective printing form and takes or transfers the multicolor image during your Contact with the rubber blankets of a collecting rubber cylinder.
  • the border zone of the color template is mainly through Introduction of a continuous, decreasing according to the filling area or stepped grid scale, whose Linear dimensions and gradation characteristics the length of the zone and determine the continuity of the color transition and the as Point or linear scale is formed, the raster line the mentioned scale in a range of values is between 8 and 40 lin / cm.
  • the gradation characteristic of the stepped Grid scale the filling areas of the fields of the grid cell of 80, 60, 40 and 20%.
  • the continuously colored line is marked with a grid scale a filling area of the fields of the haster cell of 10, 40 and 80% used.
  • a technical result when using the invention can be achieved is to create new ones artistic and technological possibilities of construction of the actual multicolored Orloff pattern, since the production a zone of constant color transition in the protective pattern it allows an iris effect within the limits of complete Capture the image in the circumferential direction produce.
  • the iris zones of the color transition enlarge the whole Richness of color of the pattern thanks to a complementary color and thanks to color tones without limiting their orientation about the extent and length of such zones.
  • Fig. 1 are the principles of zone formation the constant mixing of two colors to form one Complementary color illustrated.
  • the stencil rollers are used to ink the printing form a forme cylinder the possibility of a permanent cyclical reciprocating forced movement (M) relative given to the forme cylinder in the axial and circumferential direction, without their gear drive from the forme cylinder is disturbed.
  • M permanent cyclical reciprocating forced movement
  • One of the possible variants of the forced movement of the Stencil ink rollers can be used with a cam mechanism his.
  • the process also sees an additional transfer of colors by introducing an additional storage Stencil roller with positive displacement within the above indicated sizes before that an even mix the colors in the zone of their continuous transition.
  • the storing template represents a clay plate which according to the format of the picturesque field is equal to the area of the collective printing form.
  • the saving Stencil roller has no inking unit and takes up or transmits the multicolor image during their contact with the rubber blankets of the collecting rubber cylinder.
  • straight Orloff multi-color printing depends on the incorporation of a saving Stencil roller with positive displacement with the installation an additional template - the clay plate - as a result the arrangement of the collective printing form and the color templates one and the same forme cylinder together.
  • a grid scale In the construction of the color template is in its border zone introduced a grid scale, the density of which is different Filling area of the grid cell is specified. With respect to the border of the template, this area decreases, whereby it forms a value sequence of 100 to 0%.
  • the grid scale itself can be graded or continuously decreasing. The dimensions and characteristics of this grid scale are in the formation and formation of the zone of continuous color mixing decisive in the continuously colored line.
  • the grid line of such a scale lies in one Range of values between 8 and 40 lin / cm.
  • the width of the Raster transitions - VAR from 0 to 50 mm.
  • the length of the zone of a continuous color transition will be determined by the total size of the grid scale and lies in a value range from 1 to 25 mm and above.
  • the real one Continuity of color transition in this zone depends from the gradation characteristics of the grid scale. These requirements corresponds to e.g. a five-field scale with a Filling area of the fields of 80, 60, 40 and 20%.
  • Using a grid scale for example a fill area of 10, 40, 80% allows at least three optical densities within the boundaries of a basic color to get multicolored continuously colored line.
  • the line's different optical density by reducing the thickness of the paint layer on top of it as a result a change in the fill area of the grid scale generated color template.
  • the continuity of the color mixture and the revelation of the Zone with the complementary color in the continuously colored Line depends not only on the color characteristics of the Colors, but also from the selection of viscosity grades of the basic printing inks forming this zone.
  • the selection The viscosity index of the inks is in a range from values between 20 and 125 poise. For example are the viscosity values of two inks that form the zone of a continuous color transition for which indirect orloff printing equal to 70 and 80 poise respectively.
  • the zone is steady Color mixing in the continuously colored line 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 storage collecting roller with forced movement achieved according to claim 2, with the proviso that the Requirements of claims 3, 4 are met.
  • the fill area of these zones in the grid scales of the blue and red stencils Color accordingly forms the following series: 3a - 80% + 20%, 3b - 40% + 40%, 3c - 20% + 80%.
  • the steady zone of color transition (N) between the blue and the red base color can in the conventional methods of indirect and direct Orloff multi-color printing cannot be obtained.
  • the iris effect is within the pattern the full detection of the orientation directions on the circumference educated. In this way, this zone depends on the steady Color transition in the continuously colored line not their orientation with respect to the axis of the forme cylinder of the printing press.
