Definitions
- the present invention relates to a method and an apparatus for applying prints on reproduction papers to surfaces of heat-resistant materials, such as in particular mineral objects made of ceramic or glass or those made of metals.
- the papers used for this purpose are printed with the aid of xerocopiers or in the video printing process, these being designed as transfer papers and having a printable plastic coating on the carrier paper which can be separated from the paper.
- Such photocopy papers have z. B. a binder and pigment embedded therein, the so-called toner.
- Other papers that can be used are the so-called video printer papers that carry sublimation colors after printing.
- the heating coil located in the sleeve is subjected to an expansion stress that changes with each printing process, which damages the heating coil, and the device is susceptible to failure.
- the printing process is time-consuming because the heat builds up slowly and the elastic material of the cuff conducts the heat poorly.
- the required temperature approximately 200 ° C
- times of 5 to 8 minutes are required.
- the mechanical stress is detrimental to the paper and the color quality.
- the present invention therefore has for its object to provide a method and an apparatus for the aforementioned purposes, which has a significantly reduced susceptibility to interference, the prints can be applied much faster and with the help of which the prints are washable and scratch-resistant. For further development, a high reproducibility and a very low emission of electromagnetic radiation (EMC) should be guaranteed.
- EMC electromagnetic radiation
- This object is achieved by a method for applying prints located on reproduction papers to surfaces of heat-resistant such as mineral or metallic surfaces, in particular ceramics, wherein the paper carrying the pressure is pressed onto the surface and heated and according to the invention the heat from the Can act on the back of the object to be printed, thereby generating a temperature on the surface at which the print connects to the substrate, then peels off the backing paper and then fixes the print at elevated temperature.
- the radiation source can in principle be of any type, in a very particularly preferred manner it is a halogen lamp.
- Halogen lamps generate a temperature of 1000 ° C and above.
- the lamp can comprise one or more emitters in order to heat the substrate quickly and uniformly.
- the emitters can be combined into fields (DE 43 28 119 C2).
- the release papers bearing the illustration are placed on the outer cup wall and held with a sleeve or the like.
- the cup is then over the radiation source, e.g. a halogen lamp, put on and the bulb ignited at about half the line.
- the cup itself is a splinter protection (for the rare cases when the lamp burns out).
- the sleeve is removed, the backing paper is removed, the cup is then put back on and the print is fixed with full lamp power.
- Another advantage of the method according to the invention is that, in contrast to the prior art, the application of heat to the substrate from the rear does not require a prior coating (primer) with polyester in the case of polyester-containing release papers, which can be printed (after cleaning the surface ) should always be applied immediately.
- the heated ceramic dishes (cups, plates), as well as tiles, and other relatively thin-walled products which can be warmed in the manner according to the invention, as well as metal plates, for example signs and the like, are suitable as substrates.
- the printed surfaces can also be coated in a manner known per se.
- a device for carrying out the method consists of a housing, on the surface of which a halogen bulb is fastened in a base.
- a support surface is provided around the bulb, onto which a hollow body to be printed can be placed.
- a major advantage of such a device in addition to the fact that the sleeves do not have to contain a heating coil, is furthermore that the exchange of the sleeves for printing on different cup dimensions is very simple.
- the cuffs are firmly connected to the device and cannot be changed, so that a separate device must be used for each cup size.
- the housing has a voltage regulator and preferably a timer.
- an insulating collar is placed around the halogen bulb, on the upper edge (plate) of which the product can be placed. If the collar is large enough, it can remain stationary on the housing, e.g. Find cups to be printed with a tensioning sleeve within this space. It can preferably be opened using a hinge.
- the bulb itself can be surrounded by a sleeve made of high-temperature-resistant glass or preferably by a grid, which serves as a splinter protection.
- the temperature control is designed in such a way that the heating of the substrate becomes highly reproducible, which is essential for a constant print quality.
- the radiation source in particular a halogen lamp
- the radiation source be switched on and off continuously at a frequency that can be preceded, so that it "flickers”. This is how it works it by utilizing the temperature hysteresis of the lamp to bring the substrate precisely and repeatedly to the desired temperature level and to keep it, the pulse duration and pulse interval being able to be varied over the heating phase.
- Another decisive advantage of the pulsation of the heat source is that it enables a linear control of the heat emission. This is not the case with regulation via a dimmer.
- a 5% change in the angle of rotation of the setting potentiometer means a 50% change in temperature in the end area.
- the behavior of the lamp over heating and aging is constant.
- the linearity of the temperature setting according to the invention also makes it possible to provide a step switch with a constant setting distance between the grids for the heat pulses to be emitted per unit of time.
- FIG. 1 The device according to the invention is shown in the accompanying FIG. 1.
- a housing 1 there is a voltage regulator 6 and a timer 7 and an on / off switch 8.
- the housing has a head plate 2 with a base (not shown) for a halogen lamp 3, which is designed for a high temperature output.
- the lamp 3 is surrounded by a protective sleeve 5 which, for safety reasons, ensures that no splinters after the lamp 3 burst get outside.
- the sleeve 5 consists of temperature-resistant glass or a metal grid, the latter also ensures an even heat emission.
- the figure shows two variants for printing objects.
- the first relates to a hollow body (with a cylindrical wall), such as a cup 9, which is placed on the lamp 3 and is surrounded by a tensionable sleeve 10 and which presses the release paper 11 bearing the pressure (indicated by dashed lines) onto the outer wall of the cup 9 .
- the cup 9 can rest within an insulating collar 4.
- the second variant concerns the printing of flat objects, e.g. a plate 12. This is placed on the insulating collar 4, a pressing tool 13 pressing on the plate 12 and the release paper 11 (indicated by dashed lines) pressing on the plate 12. If this has a trough, the pressing tool 13 is designed to be correspondingly elastic.
- the halogen lamp 3 is brought to about half the power by means of the controller 6 in order to heat this substrate gently to approximately 200 ° C. Then let it cool slightly, pull off the paper layer and heat to fix with full power, whereby the substrate heats up to approx. 300 ° C.
- the heating time depends on the mass of the objects to be printed and, for conventional cup-shaped cups, is approximately 30 to 60 seconds for both processes, the individual time being set via the time controller 7.
- the heating bulb (L lamp) is switched on and off by the upstream triac (TR).
- the inertia of the heating bulb results in a clearly defined and even heat emission.
- the pulse-pause ratio of the pulse width modulator (PMW) can be set in six defined stages, so that a linear increase in heat can be achieved via the angle of rotation of the rotary switch (S).
- the upstream line filter (PVF Power Voltage Filter) does the rest.
- the pulse-pause ratios were chosen asymmetrically, ie the bulb is switched on longer than switched off.
- the pulse width modulator is controlled in time by the timer, which can be set or reset from zero to 400 seconds using the "Up", "Down” and “Reset” switches. The remaining time is shown on the display. After the printing process has been completed, the timer is reset to the automatically set time.
