Definitions
- the present invention relates to printing devices. More concretely, the invention relates to means for printing different polygraphic matter, both simple and highly artistic.
- Printing machines comprising a printing form in the form of a stencil applied on a mesh, means for applying ink onto the form and means for forcing the ink through through cells of the stencil and carrying it to the surface of the material being imprinted.
- the printing form is made in the form of a mesh covered with a layer of light-sensitive emulsion which upon exposition through a photoform under the effect of UV radiation is hardened on the space portions to be filled. The unhardened portions of the emulsion are washed off.
- the hardened emulsion is subjected to setting by thermal treatment and is covered with a special composition to protect it against acids or alkalis.
- ink is applied to the form, the ink being forced through the open cells of the mesh by a doctor blade and is transferred to the paper.
- the hardened layer is removed from the mesh, which is again covered with a light-sensitive emulsion to prepare the next stencil.
- a disadvantage of such machines is the necessity of making and setting up a printing form in order to print each run. This process is not only lengthy per se.
- the fashion in present-day polygraphy is characterized by small runs of the publications, as a result of which the time necessary to prepare a machine for operation becomes comparable with the time spent on printing, i.e. expensive equipment is used ineffectively.
- At the base of the invention lies the object of creating a printing machine which immediately after finishing printing a preceding publication could begin printing a subsequent publication without replacement of the printing form.
- a printing form is made in the form of a mesh, all the cells of which are filled with ink, and means for selectively forcing ink through the cells of the mesh is made in the form of a quantum-mechanical oscillator of a light bean, with a device for focusing it to the size of a cell of the mesh and with a device for deflecting that beam over the rows of its cells.
- the beam of the quantum-mechanical oscillator in accordance with a program, knocks out drops of ink from corresponding cells of the mesh onto paper, and since the ink is applied to all the cells of the mesh of the form in each cycle of printing, there is no need to replace the form in the machine which operates according to a program directly from the computer.
- the quantum-mechanical oscillator of the light beam be provided with a beam diameter modulator in order to expand, in accordance with the program, the zone of mesh cells which are simultaneously covered by the beam.
- the printing machine be provided with means for forcefully cleansing the mesh cells of the form of ink not transferred onto the surface of the material being imprinted after completion of one deflection cycle of the light beam.
- the proposed printing machine comprises a form cylinder 1, made in the form of a mesh with cells 2, and a printing cylinder 3, between which a paper sheet 4 moves.
- the form cylinder 1 is linked by means of rolls 5 and 6 to a vessel 7 containing ink.
- a slot nozzle 8, through which compressed air is supplied, is disposed inside the cylinder 1.
- a means 9 for selectively forcing ink through the cells 2 of the mesh is also disposed inside the cylinder 1.
- This means is made in the form of a quantum-mechanical oscillator 10 of a light beam 11 with a beam diameter modulator 12, with a device 13 for focusing the beam 11 to the size of a mesh cell and with a device 14 for deflecting that beam along the rows of cells 2.
- the proposed printing machine operates in the following manner.
- the form cylinder 1, the printing cylinder 3, the rolls 5, 6 rotate in the direction shown by the arrows, the paper sheet 4 moves and air is forced into the nozzle 8.
- ink is applied in a uniform thin layer from the vessel 7 onto the mesh of the form cylinder 1, filling its cells 2.
- the light beam 11 of the quantum-mechanical oscillator 10 is focused, deflected in a horizontal plane along the row of cells 2 of the mesh of the form cylinder 1 and, in accordance with a program, knocks ink out of corresponding cells of the mesh in each of its rows, the ink being transferred to the paper sheet 4.
- the knocking out of the ink takes place in accordance with the discovery of the "light-hydraulic effect" (Vaccina No. 65, BI No. 19, 1969), wherein when there is absorption of a quantum-mechanical oscillator light beam in a liquid, impact momentum occurs.
- a fragment of the mesh of the form cylinder 1, from the cells 2 of which ink has been knocked out, is shown in Fig. 2.
- the cells 2 of the form cylinder 1, from which ink is not transferred to the sheet 4 after passage through the zone of deflection of the light beam 11, are forcefully freed of ink by blowing compressed air from the nozzle 8 through them.
- the shape of the proposed printing machine is not necessarily cylindrical. It can also be, for example, flat and execute reciprocal motion relative to the beam being deflected transverse thereto.
- the form can also be stationary, and the quantum-mechanical oscillator beam may be deflected over the whole field thereof.
- the proposed printing machine can also print multicolored matter. In order to do this it should comprise several of the printing sections described above, and the paper sheet 4 will be sequentially passed between cylinders 1 and 3 of those sections.
- the printing machine is designed to print different polygraphic matter, both simple and highly artistic.
