Definitions

  • ABSTRACT An irridescent surface pattern comprising an array of deformations superimposed on an array of dots marked on an impressionable light-reflecting surface, the spacing between the dots and the spacing between the deformations difiering by a small percentage.
  • the dots are produced by half-tone printing on the foil of a foil-laminated sheet of paper and the deformations are produced by embossing the foil with a half-tone plate made of triacetate sheet material using a screen size different to the screen size used by the plate for printing the dots.
  • the type of irridescent decorative pattern with which the present invention is concerned is a surface pattern, different parts of which will reflect light at different angles respectively, these angles of reflection being adapted to undergo changes in response to changes in the angle of incidence of the light impinging on the patterned surface.
  • the present invention provides a method of producing an irridescent surface pattern comprising the steps of marking an impressionable, light-reflecting surface with a pattern of spaced dots and of deforming the said surface with a pattern of spaced depressions, the spacing of the depressions and the spacing of the dots differing by not less than 1% and by not more than 10% of the larger spacing.
  • the present invention also provides a sheet or other object bearing an irridescent surface pattern comprising a light-reflecting surface marked with a pattern of spaced dots and deformed with a pattern of spaced depressions, in which the spacing of the depressions and the spacing of the dots differ by not less than 1% and by not more than 10% of the larger spacing.
  • FIG. 1 is a large scale, diagrammatic representation of a small portion of an irridescent pattern
  • FIG. 2 is a cross section of part of a foil laminated sheet of paper bearing the pattern of FIG. 1, and
  • FIG. 3 is a diagrammatic view of a cylinder printing machine
  • FIG. 4 is a block-diagram summarising the method of producing the pattern.
  • FIG. 1 consists of a rectangular array of dots 1 superimposed on a rectangular array of depressions 2.
  • the effect of a depression overlapping a dot has been represented by light cross-hatching 3; this representation is, however, diagrammatic and of necessity fails to show the parallax effect caused by the bottom of the depressions being below the plane of the surface.
  • the percentage difference between the spacing of the dots and the spacing of the depressions can be clearly seen from the length 4 (10X the spacing of the dots) and the length 5 (X the spacing of the depressions) to be of the order of 5% of the larger spacing.
  • This difference in spacing has been used in the drawing for the sake of clarity but the preferred difference is of the order of 3%, whilst the preferred spacing for decorating a sheet of paper is less than l/lOOth of an inch.
  • the sheet is first printed with a pattern of dots by means of an ordinary letter-press block using a halftone 133 screen.
  • a half-tone plate is then produced which has a surface pattern of raised dots such that the number per inch of these last-mentioned dots is 3% greater or 3% less than the number per inch of the dots printed on the sheet.
  • a triacetate sheet bearing an inverted half-tone plate is produced from the said halftone plate with the aid of a solvent and a pair of rollers.
  • this triacetate sheet 10 is stuck, e.g., by means of adhesive tape 12, on the flat bed 11 of a cylinder printing machine generally indicated as 15 and the printing machine is operated, without ink, to emboss the required number of patterned sheets 8.
  • the required finished product is a picture with only the background pattern as described above, the foregound areas 14 of the picture are blanked out during the production of the patterned background and the foreground of the picture is reproduced on the blanked out area by a conventional printing process.
  • FIG. 2 A cross-section of the pattern as applied to a foillaminated paper sheet 8 is shown in FIG. 2.
  • a sheet of foil 6 on a backing of paper 7 is marked with ink dots l and is deformed with depressions 2. As in FIG. 1 the dots 1 are at a wider spacing than the depressions 2.
  • the block diagram of FIG. 4 summarises the steps used in the production of an irridescent pattern on a foillaminated sheet of paper.
  • a method of producing an irridescent pattern upon a light-reflecting surface which comprises:
  • step A embossing the marked surface resulting from step A" with a pattern of deformations corresponding to said pattern of raised projections by pressing said plate against the marked surfurace.
  • said plate is a halftone plate having a surface pattern of raised dots of the same size as said marked dots, said raised dots being 3% greater or 3% less in their number per inch than the number per inch of said marked dots.
