Definitions

  • Fig. 1 a cross-section through a transparent carrier with a layer of bichrom ated gelatine at one side
  • Fig. 2 a cross-section through the same carrier with a screen-plate applied to its hichrornated layer
  • Fig. d is a cross section through the h1-Y chromated gelatin coated carrier after exposure through the screen, which has beenl removed and with a diapositive Yapplied to the reverseside of thearrier and after exposure through said diapositive, and
  • Fig. 5 is a cross section through the transparent carrier and its bichromated gelatln after exposure and development.
  • a plate a, Fig. 1, of a more or f'less transparentnmaterial, such as cellulold, acetylcellulose (cellon), aper or the like is at ,one side covered with a layer l5 Kunststoff a thickness of 0,06 to 0,08 mm. of bichromatedgelatine in such a manner that the gelatine firmly adheres to its carrier a.
  • 'lhe screenplate c, Figs.- 2 and 3, (having transparent LED 'UNDER THE JPROVISIUNS 0F T ACT 0F MARCH 8, 1921, 41 STAT. lb., 1813.)
  • the screen c is removed and a diapositive e of the picture to lbe reproduced is applied to the reverse side of the carrier and the bichromated gelatin layer Z) is exposed to light passing through the diapositive e and the carrier b to the bichromated gelatine b, so that this portion ot itis completely tanned up to the surface of the layer, see h, i, k, Al, Figs. 4 and 5.
  • the face of the printing form is level in so -tar as the bars d, d, Flgs. 2, 4 and 5, of the screen remain of equal depth throughout the whole picture.
  • the exposure from the back of the printing plate forms a reliefv which corresponds exactly with the picture, so that at the parts of the picture where less light has penetrated recesses are ytermed between the bars of they screen, which recesses are intended to hold the ink.
  • rllhe bars of the-screen are at the surface of the bichromated-gelatne layer i5 of the same width as the lines of the screen, while they are thinner in the depth of the layer of gelatine, which is due to the fact lthat the light during the copying of the screen cannot act so intensely at lower depths ofthe layer of gelatine.
  • These extremely fine bars in the depth of the layer ot gelatine are strengthened at the' bottom of the layer by exposure through the diapositive rom the back of the printing plate so that they do not break down during the developing process.
  • an intaglio-printing form comprising a carrier plate having a level screen on one face and a relier ⁇ of the picture to be reproduced 'between the bars of said screen, the saidV screen and the said relief consisting of tanned bichromated-gelatine 3.
  • an intaglio-printing form comprising a carrier plate havinga level screen on one face, the bars of said screen being undercut and a relief of the picture to be reproduced between the said bars of said screen, the said screen and the said relief consisting of tanned bichromated-gelatine.
