Definitions

  • the present invention relates to a printed design creating three-dimensional (3D) visual effect, and more particularly to a process and compound for producing a printed design creating 3D visual effect through an interaction between magnetic particles and a magnetic body.
  • Conventional printing techniques include silk screen printing, automatic plane screen printing, pad printing, etc. All these printing techniques use mono or multiple colors to print and create only a two-dimensional flat visual effect, and therefore fail to meet the nowadays requirements for showing novel appearances by effectively upgrading a product' s visual impression or creating a 3D visual effect.
  • the color, separation in printing process is now carried out using a computer, and a gray scale is employed in printing to present a 3D effect.
  • the computerized printing equipment is expensive to largely increase the cost of printing, while the simulated 3D effect is limited.
  • a primary object of the present invention is to provide a process and a compound for producing a printed design creating 3D visual effect through an interaction between magnetic particles and a magnetic body.
  • the compound of the present invention consists of a printing ink blended with magnetic particles
  • the process of the present invention includes the steps of applying the printing ink containing magnetic particles onto a printing plate on a printing apparatus, and positioning a tool capable of producing a required magnetic force at a predetermined area of the applied printing ink, so that the magnetic particles in the area are attracted and gathered to form ups and downs in the area and create a 3D visual effect.
  • the compound of the present invention consists of 65 ⁇ 95wt% of printing ink, and 5 ⁇ 15wt% of magnetic particles.
  • the printing ink is added with dyes to adjust the color thereof.
  • Fig. 1 shows the mutual relation between magnetic particles in a printing ink of the present invention and a magnetic body.
  • a printing ink 11 blended with magnetic particles 10 is applied onto a printing plate 12, and a magnetic body 13 is positioned beneath an area of the applied printing ink 11, at where a three-dimensional (3D) surface is to be created, the magnetic particles 10 in the still wet printing ink 11 are attracted by the magnetic body 13 to gather in the area and create ups and downs therein to show a 3D visual effect.
  • 3D three-dimensional
  • the printing process creating 3D visual effect according to the present invention is different from the conventional printing techniques in that the present invention may be implemented with an existing printing apparatus 15 (see Figs. 3, 4, and 5) without the need of designing a new one.
  • a compound disclosed in the present invention which is a type of printing ink, for producing printed design creating 3D visual effect cooperates with a magnetic tool 16, so that magnetic particles 10 contained in the compound of the present invention are attracted and gathered by the magnetic tool 16 to create the 3D visual effect.
  • the compound of the present invention includes 65 ⁇ 95wt% of printing ink 11, 5 ⁇ 15wt% of magnetic particles 10, and 5 ⁇ 30wt% of dyes, which are well blended.
  • the magnetic particles 10 added in the printing ink 11 react to magnetic force when the printing ink 11 is still wet, and are differently distributed under the magnetic force to create the 3D visual effect.
  • the magnetic particles 10 are iron oxide red (Fe 2 O 3 ).
  • Another example of the compound of the present invention includes 65 ⁇ 95wt% of printing ink, and 5 ⁇ 15wt o of magnetic particles, which are well blended. When it is desired to create a black and white printed design, simply mix the printing ink 11 of a primary color with the magnetic particles 10 directly.
  • the printing ink 11 may contains polyvinyl, polyvinyl chloride, urethane resin, isophorone, cyclohexanone, phenyl alkyl solution, and ethylene glycol solution.
  • FIG. 2 shows the structure of a tool 16 used in the present invention to produce magnetic force.
  • the tool 16 uses magnet or electric current to produce magnetic force of the same polarity or different polarities, or different intensity to cause changes in the distribution of the magnetic particles 10 in the printing ink 11.
  • the tool 16 is referred to as a bottom-attraction tool herein, which is able to produce fallings on the applied printing ink 11 to create a 3D visual effect; and when the magnetic tool 16 is positioned above the printing plate, as shown in Figs. 3 and 4, the tool 16 is referred to as a top-attraction tool herein, which is able to produce raisings on the applied printing ink 11 to create a 3D visual effect.
  • the magnetic tool 16 may include a winding and be supplied with electric current to produce the magnetic force. With this type of tool 16, it is possible to adjust a magnitude of the magnetic force produced, so as to create different 3D visual effects.
  • a screen plate or a stencil plate is first positioned on the printing plate 12, so that the printing ink 11 is coated on the printing plate 12 according to the design or designs defined on the screen plate or the stencil plate. Since the printing ink 11 has magnetic particles 10 blended therewith, it is possible to create a 3D visual effect at a predetermined area of the applied printing ink 11 on the printing plate 12 through arrangement of the magnetic body 13 below the printing plate 12 corresponding to the predetermined area.
  • a printing apparatus 15 which includes a scraper 17 (see Figs. 3 and 5), a pad printer, or the like.
  • a protective layer 14 may be applied over the finished 3D printed design, as shown in Fig. 1.
