  • Digital image data are used to expose a photosensitive material by applying light point by point to the photographic paper.
  • the light pulse for exposing a pixel on the photographic paper is in each case by a light-emitting diode (LED), according to the stored digital image information, generated and passed through an optical fiber in an exposure head, through which the light pulse is finally directed to the photographic paper.
  • the outlet ends of a plurality of optical fibers are in a frame of the exposure head immediately adjacent to each other, strung together.

  • the advantage is achieved so that the exposure head only requires a third of the number of optical fibers.
  • this also has the further advantage that the three colors for generating a pixel are thus applied simultaneously, and thus a higher accuracy is achieved compared to the otherwise necessary, successive exposures of the individual colors on a pixel.
  • the advantage of the design of the device according to claim 2 is that due to the characteristic of the course of the spectral transmittance of the interference filter used, an optimum yield of light of the light sources used is achieved.

  • the light sources 14, 15, 16 are each held in a holder or a tube 30, 31, 32 and their light is focused in each case by a lens 33, 34, 35.
  • the tubes 30, 31, 32 or optical axes 36, 37, 38 of the lenses 33, 34, 35 are aligned approximately star-shaped.

  • interference filter 40, 41 for deflecting the beam path of the light sources 14, 15 offers the advantage that light losses can be kept particularly low.
  • interference filters are formed by alternating-layer systems, ie multiple layers with alternating high and low refractive indices. Since the layers are virtually free of absorption, a nearly lossless division of a spectral range to reflection and transmission is possible, the limit being determined by a steep edge of the transmission curve.
  • a filter is used for the interference filter 40 whose spectral transmittance for red light is almost zero, while light of a smaller wavelength range, such as the green light of the light source 15 and the blue light of the light source 16 Interference filter can pass almost unattenuated.
  • the red light of the light source 14 is reflected and passes through the entrance hatch 29 in the optical fiber 18.

  • the hatches 48 are in each case consecutive lines 50, also in the lateral direction, ie with respect to the directions 11, 12 added.
  • this lateral displacement of the hatches 48 must be taken into account by a corresponding time delay of the transmission of the data of the digital image 3 to the drive circuit 20 (FIG.
  • the mask 47 is preferably formed from a glass sheet provided with a coating. For exact mounting in the exposure head 8, the mask 47 also has centering marks 51.
  • FIG. 5 shows a greatly enlarged detail of the mask 47 with two hatches 48, according to FIG. 4.
  • the illustrated section shows two hatches 48 and dashed lines indicated exposure strips 52, as they are generated by the passage of the hatches 48 in the direction 11 on the photosensitive material 2.
  • the exposure head 8 (FIG. 1) over the material 2 only every second line 50 is generated by the lines of the digital image 3 to be generated.
  • the generation of corresponding intermediate lines 53 ensues, during a second movement of the exposure head 8, on the basis of the data of the digital image 3.
  • successive lines 50, 53 thus have a line spacing z 54 whose value is equal to half the hatch distance d 49.
  • This method of applying nested lines 50 and intermediate lines 53 is also referred to as interlacing.
  • each hatch 48 perpendicular to the direction 11, 12 of the movement of the exposure head (8) has a height 55 whose value is greater than the line spacing z 54.
  • the exposure strips 52 of lines 50 and exposure strips 56 of FIG Intermediate lines 53 between each successive lines 50 and intermediate lines 53 overlap each other. This can be avoided unwanted streaking.
  • a width 57 of the hatch 48 has a value which is greater than the line spacing z 54. Both the height 55 and the width 57 of the hatch 48 thus extend beyond the maximum theoretical areal extent of a pixel. This corresponds just to a square with a side length which is equal to the line spacing z 54.
  • width 57 of the hatch 48 is consequently also an overlap between adjacent Pixels within a line 50, 53 reached.
  • the lateral overlap with respect to the direction 11, 12 is additionally increased by moving the exposure head 8 continuously over the photosensitive material 2 (FIG. 1). This overlap of the exposure areas of individual pixels in the lateral direction 11, 12 results from the path traveled by the exposure head 8 or the hatch 48 during the duration of an exposure pulse.
  • the maximum duration of an exposure pulse is equal to the transit time for covering the width of an exposure point corresponding to FIG Line spacing z 54.

Points of material 2 near the maximum width of the hatch 48, i. in an area near the width 57 of the hatch 48, are thus exposed to the exposure of a light pulse much longer than is the case for other points. This is symbolically indicated by exposure curves 60 of the exposure strips 52 and exposure curves 61 of the exposure strips 56, respectively. It is easy to see that in areas where exposure strips 52 and exposure strips 56 overlap one another, the exposure curves 60, 61 overlap, resulting in an overall exposure curve with approximately constant progression and no abrupt changes.
  • the height 55 as well as the width 57 of the hatch 48 are preferably equal to 1.8 times the line spacing z 54.
  • T difference stands for the time duration between the first exposure process and the second exposure process at the same location of the material 2.
  • the method for correcting the intermittency effect thus consists in first producing at least one first line 50 of pixels 53 during a first movement of the exposure head 8 and subsequently producing at least one second line 53 of pixels 62 during a second movement of the exposure head the first row 50 and the second row 53 at least partially overlap each other.
  • corrected image data for the second line 53 is calculated by compensating for the changed exposure effect of the second exposure process for each of the pixels 62. This compensation is effected by a change in the intensity and / or by the change in the pulse duration of the corresponding exposure pulse by a value which is proportional to the logarithm of the ratio of the time interval between the exposure of the pixel 63 and the exposure of the pixel 63 and a reference time interval.
  • FIG. 6 shows an enlarged section of the photosensitive material 2 with the lines 50 exposed thereon and an intermediate line 53.
