Definitions

• the invention relates to a method for producing a transparency with a plurality of identical characters of different sizes arranged one above the other at a distance, which are arranged in a closed light box and are illuminated from the rear by means of a light source, according to the preamble of claim 1.
• the invention characterized in claim 1, that is to say a method for producing a transparency with a plurality of identical characters of different sizes arranged one above the other, which are arranged in a closed light box and are illuminated from the rear by means of a light source , which is characterized by arranging a first positive motif film on the back of a first translucent pane, arranging a first template with a negative motif that is slightly larger than that of the first positive motif film, at a short distance from the back of the first pane, applying a first semi-transparent color with a first color through the first template onto the back of the first pane, the area covered by the first template remaining approximately free.
• Figure 1 is a sectional view of a light box.
• FIG. 3 shows a top view of a first pane with a first positive motif film
• FIG. 4a shows a schematic view of the application of a first semi-transparent color to the first pane
• 4b shows a schematic view of the application of a second transparent color to the first pane
• 4c shows a schematic view of the first pane after removal of the first positive motif film
• 5a shows a schematic view of the application of a third color to a second disk
• 5b shows a schematic view of the second disk after the application of the third color
• 6a is a schematic view of the application of a fourth color to the back of the second disk
• 6b shows a schematic view of the second pane after the fourth color has been applied
• Fig. 7 is a schematic view of the relative position of the first and second disks to each other.
• FIG. 1 shows a sectional side view of a light box 3 with a rear wall 4, in which a light source 5 is arranged.
• a first pane 1 and a second pane 2 are arranged at a distance from one another, the second pane 2 being closer to the light source 5 than the first pane 1.
• the first Disc 1 serves as a cover for the light box and its edges can protrude beyond the circumference of the light box.
• the light box 3 and the rear side 4 can be made of wood, plastic or another suitable material.
• the panes 1 and 2 are made of glass, plastic or another translucent material.
• a first positive motif film 10 is arranged on the back of the first translucent pane 1 (see FIG. 3).
• a first template 12 with a negative motif, which is somewhat larger than that of the first positive motif film, is arranged thereon at a short distance from the rear of the first pane 1.
• a first semi-transparent color with a first color tone is then applied by the first template 12 to the back of the first pane 1, the area covered by the first template 12 remaining approximately free (see FIG. 4a).
• a second transparent color with a second, somewhat lighter color tone than that of the first color is applied to the first color by the first stencil 12 (see FIG. 4b).
• the first positive motif film 10 and the first template 12 are then removed from the back of the first pane (see FIG. 4c).
• a second positive motif film 14 is then applied to the back of the second pane 2, the second positive motif film 14 being somewhat larger than the first positive motif film 10.
• a second template 16 with a positive motif, which is somewhat larger than that of the second positive motif film 14, is then applied at a short distance from the rear of the second pane 2.
• a third color, preferably white in color, is applied or sprayed onto the back of the second pane 2, the area covered by the second stencil 16 remaining approximately free.
• the second positive motif film 14 and the second template 16 are then removed from the back of the second pane 2 (see FIG.
• a third stencil 18 with a positive motif which is somewhat larger than that of the second stencil 16, is applied at a short distance from the front of the second pane 2, and a fifth color, preferably with a white shade sprayed onto the front of the second pane 2, the area covered by the third template 18 remaining approximately free.
• the slices treated in this way are then also arranged in the light box, as described above.
• the first template 12 is preferably arranged at a distance of approximately 2 to 3 mm from the rear of the first pane 1, and the second positive motif film 14 has an overhang of approximately 1 to 4 mm compared to the first positive motif film 10.
• the second template 16 has an overhang of approximately 5 to 20 mm compared to the second positive motif film 14 and is arranged at a distance of approximately 2 to 5 mm from the rear of the second pane 2.
• the first and second disks 1, 2 are mounted in the light box 3 at a distance of approximately 5 to 10 mm.
• the paint can be applied in any suitable manner, but is preferably spray applied.
• the film is preferably a self-adhesive film.
• the entire surface of the two panes can be coated with protective lacquer.
• the front of the first disc should be treated accordingly.
• the colors used can be applied individually, mixed or merging, sharply contoured or running, with the color being applied in any way, for example by means of spraying or screen printing.
• Such movement can e.g. can be achieved in that the second disc 2 is guided on a guide and driven by means of a crank mechanism driven by an electric motor.
• the movement can be in the horizontal and / or vertical direction.
