Definitions

  • the invention relates to an inkjet printing system, in particular to an inkjet printing machine and to a formulation unit for an inkjet printing machine and to a method for preparing ink for the inkjet printing system.
  • ink for inkjet printing machines is prepared from specialised ink manufacturers in ink production plants with an output capacity between 50 to 300 liter per batch. With these production facilities only one color is produced at a time. Because of the large batches often corrections have to be made to the ink to achieve the correct rheology. After the preparation of every batch the facility has to be cleaned for the next color.
  • the ink which consists to 50-60% of water is filled in usually 5 or 10-liter shipping canisters and is sent all over the world. Since most manufacturers promise a 2-year shelf time the ink needs to be stabilized with a high level of solvent and for some type of ink anti-fungi chemicals to make it stable.
  • one problem to be solved by the present invention is to reduce logistical efforts for supplying ink to printing systems. Additionally, the quality of the ink as to air bubbles and required solvent and anti-fungi chemicals should be increased.
  • WO 00/44569 discloses a formulation unit for an inkjet printing machine.
  • the problem is solved by a formulation unit for an inkjet printing machine as defined in claim 1.
  • the ink does not have to be filled in canisters and to be shipped to the printing machine. In this way it is possible to prepare the ink when it is needed in the printing process and in particular also in a lower quantity. Thus fewer chemicals for preserving the ink are necessary and the logistic costs for providing the ink can be reduced.
  • a further preferred embodiment of the formulation unit comprises at least two preparation devices and at least two storage tanks connected to said preparation devices, for the preparation and the storage of the same or respectively different inks.
  • Such an embodiment allows for example to prepare two or more ink colors at the same time. It is also possible to produce besides different colors also a different kinds of ink or another chemical (here also referred to as "ink"), for instance for a treatment of the substrate.
  • every preparation device serves for the preparation of one ink it is not necessary to clean the preparation device after every ink preparation procedure, inducing less water consumption for cleaning. It is considered as suitable to clean the preparing device approximately every 2 to 4 weeks of machine time, which means very easy maintenance.
  • connection from a storage tank to the printing device of a further preferred embodiment of the formulation unit is adapted to supply ink continuously from the storage tank to the printing device during the printing process.
  • the storage tank of the formulation unit is constantly conneted to the printing device.
  • the preparation device is adapted to prepare ink which is supplied to the storage tank while ink is supplied from the storage tank to the printing device in particular according to the demand of the printing device. In this way, the supply from and to the storage tank can take place concurrently and independently.
  • This also involves the possibility to establish a partially or wholly automated process where ink is prepared in the preparation device according to the filling level of the storage tank and/ or according to the demand of the printing device.
  • the ingredients of the ink have to be filled manually into the preparation unit, for example a dye in form of powder or in form of a color-concentrate, which are difficult to handle and to dose, from a prepared package, or a certain volume of the necessary additive chemicals or of deionized water.
  • the amount of additive chemicals and deionized water is for example defined by the package size of a dye-powder.
  • a dye-powder is still filled in manually, wherein the deionized water and the additive chemicals are added by means of known automated metering equipment.
  • a color-concentrate is used for preparing the ink, which already contains the necessary additive chemicals and only deionized water needs to be added.
  • dye-powder, dye-fluid or color-concentrate are referred to as "dye" irrespective of whether or not all necessary chemicals are already contained in the dye. Where appropriate, a distinction will be made.
  • the formulation unit comprises a dosing device for automatically dosing at least one ingredient of the ink, in particular the dye.
  • a dosing device for automatically dosing the dye enables a wholly automated process for preparing ink in the formulation unit, in particular also on demand.
  • a dosing device for automatically dosing the dye enables also the preparation of different volumes of ink, for example for preparing a smaller amount of a sparsely used ink in a printing procedure.
  • the formulation unit comprises a degassing device which is arranged between the preparation device and the storage tank and wherein the storage tank is a buffer vacuum container which is connected directly to the ink inlet of the printing device.
  • the ink is directly supplied to a storage tank which is a buffer vacuum container and therefore does not contain gas or air that could incorporate into the ink.
  • the outlet of the buffer vacuum container is connected directly to the ink inlet of the printing device. This tubing is also free from gas or air that the ink can be jetted with high quality onto a substrat.
  • an inkjet printing machine with a formulation unit and a printing unit.
  • the printing unit comprises a printing device for jetting ink onto a substrat, an ink supply device for supplying ink to the printing device and a substrat supply device for supplying the substrat to the printing device.
  • the formulation unit of the inkjet printing machine is designed as described before.
  • the size of the formulation unit is small as also the amount of ink which is prepared in one preparing process.
  • ink distribution canisters and also storage tanks of known inkjet printing machines contain unsually several liters of ink for longer printing periods which means long residence and storage times particulary for ink with small output quantities.
  • the formulation unit of the injet printing machine according to the invention allows frequently preparing and storing smaller volumes of ink according to the demand of the printing process and printing device respectively. In this way a simple, reliable and thus economical installation with very easy maintenance is provided.
  • the substrate on which the printing device of the printing machine jets ink is preferably a textile.
  • the invention for inkjet printing machines for other substrats like paper or films, foils or any other substrate suitable for inkjet printing.
  • the problem is solved by a method for preparing an ink using a formulation unit in particular as described above.
  • the method depends on the kind of the dye used.
  • the method is especially suitable for being performed by using the above described formulation unit, and in particular with an injet printing machine as described above.
  • any other suitable formulation unit for performing the method, a dye designed as color-concentrate is used, which contains further chemicals, in particular solvents necessary to prepare ink.
  • a first step (a) the tank is filled with a first amount of deionized water.
  • a preferred amout for the first filling is about one third of the final volume of water.
  • Deionized water is required for maintaining the purity of the product at a maximum level.
  • a certain amount of a dye preferably in form of a color-concentrate according to the volume of the prepared ink is put into the tank.
  • the color-concentrate is heated up to 30°C, preferably up to 50°C, preferably up to 55°C, preferably up to 70°C prior to being mixed with deionized water.
  • the advantage of using the dye in form of a color-concentrate is that dust formation can be reduced, preferably prevented.
  • a third step (d) the indegrients within the tank are mixed in a way that the dye, preferably in form of a color-concentrate dissolves completely and possibly no air is introduced into the fluid.
  • a second amount of deionized water (a preferred amount is two third of the final volume) is added to the tank and in a fifth step (f) the indegrients within the tank are again mixed to dissolve the ingredients completely and in a way to avoid the introduction of air into the fluid.
  • the indegrients and the formulation unit are adapted such that the whole process takes less than 10 minutes which means high flexibility and low logistic costs as the lead time for the preparation of ink is very short.
  • the method comprises the steps:
  • the second embodiment differs from the first embodiment of the method in an additional step b) wherein additive chemicals are added to the water in the tank. Those chemicals serve in particular for enhancing the dissolution of the color concentrate (for example Hostapal or DEG).
