Definitions

  • the invention relates to a printing machine, comprising a flexible support, which is coated with a paint réellesudruckenden, and a device for introducing energy into the ink, wherein the device for introducing energy is arranged so that the energy in a pressure range on the Color remote side can be introduced so that color is transferred from the carrier to a substrate to be printed.
  • the invention further relates to a process for printing a substrate, wherein in a first step, ink is applied to a flexible support and in a second step, the ink is transferred from the flexible support to the substrate according to a predetermined pattern by applying energy through the flexible substrate Carrier is introduced into the paint, evaporates a solvent contained in the paint in the Einwirk Scheme the color and thereby a drop of paint is thrown on the substrate to be printed.
  • a method for printing on a substrate, in which drops of paint are thrown from a color-coated carrier onto a substrate to be printed is for example off US-B 6,241,344 known.
  • energy is introduced by the carrier into the ink on the carrier at the position where the substrate is to be printed.
  • a part of the color evaporates, so that it dissolves from the carrier.
  • Due to the pressure of the evaporating paint the ink droplet thus dissolved is thrown onto the substrate.
  • the necessary energy for transferring the color is introduced, for example, by a laser.
  • the carrier on which the paint is applied for example, is a circulating belt, on which by means of a coating device in front of the printing area color is applied.
  • the laser is located inside the circulating belt, so that the laser acts on the carrier on the side facing away from the paint.
  • a corresponding printing machine is still for example also off US 5,021,808 known. Again, color is applied from a reservoir with an applicator on a circulating belt, which is within the circulating belt, a laser through which the ink is evaporated at predetermined positions and is thrown onto the substrate to be printed.
  • the tape is made of a transparent material for the laser.
  • the circulating belt is coated with an absorption layer in which the laser light is absorbed and converted into heat, and thus evaporates the color at the exposure position of the laser.
  • the application of the paint on the flexible support is generally carried out by rolling mills, wherein a roller immersed in a paint-containing reservoir and the color is transferred by means of the roller on the flexible support.
  • the object of the present invention is to provide a printing machine and a method for printing on a substrate, in which fluctuations in the print quality are avoided by inhomogeneities of the flexible carrier.
  • any distortion waves occurring in the flexible support are smoothed. As a result, a homogeneous surface in the printing area can be achieved.
  • the term "pressure range" refers to the region in which energy is introduced into the ink, a portion of the ink evaporates and a color drop is thereby transferred to the substrate to be printed.
  • the pressure gap that is to say the gap between the flexible support with the ink applied thereto and the substrate to be printed, is moreover evened out. Different gap widths, e.g. caused by waves in the flexible carrier are thus prevented and thereby improves the printed image.
  • the pressure gap can be adjusted by moving the tensioning device in the direction of the substrate to be printed or away from it.
  • the tensioning of the flexible carrier and the planar surface produced thereby ensures that the drop of color leaving the flexible substrate, which is thrown onto the substrate to be printed, follows a targeted path that runs essentially perpendicular to the direction of the flexible carrier. This allows a clean print image can be achieved.
  • the substrate to be printed and the color-coated flexible support have a printing gap in the range from 0 to 2 mm, in particular in the range from 0.01 to 1 mm.
  • the smaller the printing gap between the flexible support and the substrate to be printed the less the droplet expands when it strikes the substrate to be printed, and the more uniform the printed image remains.
  • care must also be taken to ensure that the substrate to be printed does not touch the color-coated flexible support, so that ink is not transferred from the flexible support to the substrate to be printed in undesired places.
  • the energy is preferably introduced focused into the color by the flexible carrier.
  • the size of the point to which the energy to be introduced is focused corresponds to the size of the point to be transferred as a function of the substrate.
  • points to be transferred have a diameter in the range of about 20 ⁇ m to about 200 ⁇ m.
  • the size of the point to be transferred may differ depending on the substrate to be printed and the printed product produced therewith. For example, it is possible to choose a larger focus, especially in the production of printed circuit boards.
  • printed matter in which a font is displayed generally has small printing dots for producing a clear typeface prefers. Even when printing images and graphics, it is advantageous to print as small dots as possible to create a clear image.
  • the flexible carrier used in the printing machine which is coated with the ink to be printed on, is preferably configured in the form of a ribbon.
  • the flexible carrier is a film.
  • the thickness of the flexible carrier is preferably in the range of 1 to about 500 microns, in particular in the range of 10 to 200 microns. It is advantageous to carry out the flexible carrier as possible in a small thickness, so that the energy introduced by the carrier is not scattered in the carrier and so a clean print image is generated.
  • transparent polymer films are suitable, for example, for the energy used.
  • the flexible carrier is stored in a suitable device.
  • the carrier which is coated with paint
  • the carrier coated with ink is then unwound and passed over the printing area, in which color is transferred from the carrier to the substrate to be printed with the aid of the laser. Subsequently, the carrier is rewound for example again on a roll, which can then be brought to disposal.
  • the flexible support is designed as a circulating belt.
  • ink is applied to the flexible support with a suitable applicator before it reaches the printing position, ie the point at which the ink is transferred from the support to the substrate to be printed with the aid of the energy input. After printing, some of the ink has been transferred from the support to the substrate. As a result, no homogeneous color film is on the support. Thus, for a next printing operation, it is necessary to coat the support again with paint. This is done the next time the corresponding position on the paint application device. In order to avoid that the ink dries on the flexible support and in order to produce a uniform ink layer on the support, it is advantageous to first remove the paint present on the support before a subsequent application of ink to the support.
  • the removal of the paint can be done for example by means of a roller or a squeegee. If a roll is used to remove the paint, it is possible to use the same roll with which the paint is also applied to the backing. For this purpose, it is advantageous if the rotational movement of the roller is in the opposite direction to the movement of the flexible carrier. The color removed from the flexible carrier can then be returned to the ink supply. Alternatively, if a roller is provided for removing the paint, it is of course also possible to provide a roller for removing the paint and a roller for applying paint.
  • the ink is to be removed from the flexible carrier with a doctor blade, then any doctor known to those skilled in the art can be used.
  • the flexible support In order to avoid that the flexible support is damaged when applying the paint or when removing the color, it is preferred if the flexible support with the aid of a counter roll against the applicator roll, with which the color is applied to the carrier Roll that removes the paint from the backing or presses the squeegee that removes paint from the backing.
  • the backpressure is adjusted so that the color is substantially completely removed, but there is no damage to the flexible support.
  • the tensioning device comprises at least two guide elements, which are arranged on both sides of the device for introducing energy.
  • at least one guide element in the transport direction of the flexible support in front of the device for introducing energy and at least one guide element behind the device for introducing energy is arranged.
  • the flexible carrier is tensioned precisely in the region in which the energy is introduced and the ink is transferred to the substrate to be printed.
  • the distance of the guide elements is preferably chosen so that this is at most twice as wide as the device for introducing energy. If the energy is introduced with a laser, it is even possible for the spacing of the guide elements to correspond to the width of the laser beam used, so that it can be passed undisturbed between the guide elements. Due to the small spacing of the guide elements, even a small force for tensioning the flexible carrier is sufficient to achieve a flat surface of the flexible carrier in the pressure region.
  • Suitable guide elements are for example tension rollers, air cushions or stationary rods.
  • tensioning rollers When tensioning rollers are used as guide elements, they can rotate at a circumferential speed which corresponds to the speed of the flexible carrier.
  • it is also possible, in particular to achieve an improved clamping and thus a flat surface of the flexible support when the tension roller, which is arranged in the transport direction of the flexible support behind the device for introducing energy, a greater peripheral speed than the speed of the flexible support, or alternatively, if the tension roller, which is in the direction of travel of the flexible support in front of the device for introducing energy, moves at a lower peripheral speed than the speed of the flexible support.
  • both the idler before the device for introducing energy runs slower than the speed of the flexible carrier and the idler disposed behind the device for introducing energy runs faster than the flexible carrier.
  • the tensioning rollers can each be provided with its own drive, or a drive is provided for both tensioning rollers.
  • the connection of the tension rollers can then be done for example via a transmission.
  • stationary rods are used instead of tensioning rollers along which the flexible carrier runs, these are preferably formed without sharp edges, in particular on the surfaces along which the flexible carrier is guided, in order not to damage the flexible carrier.
  • Particularly suitable are rods with a circular, an oval or any other curved cross-section, which has no edges, in particular in the region in which the flexible support is guided.
  • the rods are cylindrical, i. designed with a circular cross-section.
  • the material of the surface of the stationary rods is chosen so that it has only a low coefficient of friction compared to the material of the flexible support. In this way it can be avoided that the flexible carrier adheres too strongly to the stationary rod used as a tensioning element.
  • the guide elements are rigidly fixed in position. Only when using tension rollers, a rotational movement can take place. A radial movement of the guide elements is not possible in this case.
  • the guide elements are movably mounted, it is also possible, for example, for the guide elements to be directed towards or away from one another can be moved away. Suitable guides and bearings, with which such movements are possible, are known in the art.

  • the tensioning device comprises a guide element which is permeable to the energy used.
  • the guide element which is permeable to the energy used is in this case directly at the pressure area. That is, the guide member is positioned between the energy delivery device and the flexible support so that the energy with which the ink evaporates from the support and is transferred to the substrate must be passed through the guide member.
  • a laser is preferably used as energy used to vaporize the ink and transfer it to the substrate to be printed.
