Definitions

  • the invention relates to a method for producing an original, in which a recording layer located on a carrier is exposed in terms of information and lattice to form a relief image, the recording layer being exposed through separate color separation templates which are transparent in the area of the respective projection color and whose partial image areas overlap-free adjoin each other, and in which the recording layer is developed after exposure.
  • a nickel matrix with different relief depth is created separately, with which one of the separate embossed images is created.
  • the relief depths are different, with the relief depth being greatest for the cyan extract and smallest for the yellow extract.
  • These embossed images are rasterized.
  • the embossed images are overlaid on a three-layer relief image from which colored images can be projected. The technique described produces very bright, high resolution color images.
  • the relief images can be reproduced relatively cheaply and quickly by embossing.
  • the object of the invention is to improve the method described in the introduction in such a way that, with at least the same quality of the projection images in terms of brightness and sharpness, time is saved in the exposures of the recording layer.
  • the procedure is such that up to a uniform relief depth, that of a certain one Projection color corresponds, is exposed lattice.
  • the grating depth for the respective color separation image is thus adjusted in the case of the grating-free image-wise exposure.
  • the explanation for this seems to be that the relief depth initially increases in a lattice construction phase, since the exposed parts of the layer expose faster than the layer parts previously covered by webs of the structural lattice, and then there is a lattice removal phase in which the relief depth decreases again, especially when approaching to the wearer in the final stage of the exposure.
  • the lattice structure and lattice degradation is largely independent of the layer thickness of the recording material, for example a photoresist.
  • the reproducibility and the luminosity of the projection colors are in any case the same or even better than if the recording material is exposed immediately in a grid-like manner until the support is reached.
  • the image is produced in such a way that a new layer of photoresist is exposed with a grid of 240 mJ / cm 2 .
  • exposure is carried out under suitably placed color separation templates, which are only transparent at the image areas of the respective color separation color and at the white image areas, namely to achieve the projection colors red / yellow / blue, the color separation templates with energy densities of 70/90/120 mJ / m 2 shines through.
  • a black separation template is crossed over to the grating and a grid of 138 lines / mm is placed on the pre-exposure and an energy density of 140 mJ / cm 2 is irradiated.
  • the original obtained is irradiated with white light and a colorful image is projected according to the original by means of an optical system with a light intensity of 1: 2.8.
  • the black parts of the image can be described as dark brown rather than black.
  • the spectral transmissions, which are shown in the figure, were measured at the colored image points. Above a scattered light component of approximately 3%, transmissions with maximum values of around 50% build up, curve A for blue-violet a maximum at approximately 460 nm, curve B for green a maximum at approximately 510 nm, curve C for yellow Maximum of approximately 620 nm and curve D for red, with an orientation towards magenta, have a maximum at approximately 650 nm.
  • the exposure times must be multiplied by a factor of 1.06 for the corresponding color rendering of the embossed PVC foils to take into account different refractive indices between PVC film and the photoresist layer.
  • An approximately 2.5 .mu.m thick layer of a sensitometrically harder photoresist than in Examples 1 and 2 is irradiated in a contact arrangement with a grid of 600 lines / mm made of metal bars on a glass plate with actin-safe light, developed in aqueous alkaline solution and irradiated with white light.
  • the projection light is imaged by optics with a light intensity of 1: 2.8. Depending on the energy densities supplied, the following projection colors appear in table 3, column 2.
