Definitions

  • the invention relates to a method for curing a UV-curing Printing ink on a substrate in which the Printing ink irradiated with UV light from a UV radiation source becomes. Furthermore, it focuses on a corresponding one Device for irradiating the printing ink with UV light.
  • UV-curing printing inks are low-solvent or solvent-free, radiation-curing inks and have in more and more important recently. This is due to the fact that the energy of UV radiation is high and therefore in printing processes for printing on Printing materials with high printing speed, in particular in flat or high pressure, is an advantage. Also in practical application, for example in relation to the pot life, the solvent pollution of the environment and the Dispose of them in contrast to solvent-based paints application technology advantages.
  • UV-curing inks have a UV-curable binder system from a polymerizing binder or Binder mixture and one or more associated Photoinitiators on.
  • the polymerization can be carried out by UV radiation or networking are triggered, whereby the Color hardens.
  • Known radical polymerizing binders are based of acrylates, whereas the cationically polymerizing ones by one released during UV radiation Mark acidity.
  • the invention is directed independently from the special binder system in general to the Curing UV-curable printing inks.
  • UV-curing printing inks are, for example the following: sheet offset printing (e.g. packaging), Endless offset printing (e.g. direct mail items), Dry offset (indirect high pressure, e.g. cups and tubes), Label printing (book and flexo printing), flexo printing (e.g. packaging films) and screen printing (e.g. technical Parts).
  • sheet offset printing e.g. packaging
  • Endless offset printing e.g. direct mail items
  • Dry offset indirect high pressure, e.g. cups and tubes
  • Label printing book and flexo printing
  • flexo printing e.g. packaging films
  • screen printing e.g. technical Parts.
  • the advantage of UV curing, often called UV drying is called is that the solvent-free or low-solvent printing inks due to UV radiation dry quickly on the substrate so that these are immediately processed or packaged can.
  • the invention is directed to the hardening of the printed Ink and is therefore independent of one special printing process with which the printing ink on the Printing material is applied
  • the arc length of the conventionally used spotlights varies between 10 cm and 220 cm and the specific electrical power ranges from 30 to 250 Watts per centimeter of arc length.
  • the UV light output is about 20 watts per centimeter of arc length.
  • the light tube material exists because of the requirement for UV light transmission made of quartz and the lamps come with operated at a gas pressure of 1 to 2 atm.
  • Lasers in particular excimer lasers, are also used used to generate the UV radiation.
  • the aforementioned, conventionally used UV radiation sources have the advantage that with them a very high area-related UV intensity on the substrate can be generated and therefore very short curing times can be realized in the range of tenths of a second can lie.
  • the disadvantage of excimer lasers is the high one technical effort.
  • the medium pressure and high pressure gas discharge lamps are more common for this reason.
  • they have the disadvantage that their efficiency for the emission of UV light in the relevant spectral range is only about 20%, so that 80% of the supplied Energy is lost and dissipated by cooling must become.
  • the surface temperature of the lamps in the range of 800 to 900 ° C, which is special technical Measures to cool the environment required. Because the lamps not restarted immediately after switching off precautions must also be taken that when the press is at a standstill, the substrate or the printing ink applied to the substrate cannot burn. For this reason are further Heat protection glasses, also in cooled form, as well as swiveling ones Reflectors provided. With a printing press the state of the art, which is a total power consumption of 100 kW, the proportion of the dryer unit more than 50 kW, typically 80 kW.
  • the present invention takes this state into account the technology is based on the task, a method and a corresponding device for curing a UV-curing To create printing ink on a substrate, which the Disadvantages more commonly associated with the high heat development Avoids UV gas discharge lamps.
  • Under spectral Radiant flux is the radiant power in watts per nm understood as a function of the wavelength.
  • the radiation flow is a measure of the intensity of the radiation. By Integration or summation of the spectral radiation flow over a wavelength interval you get that in this Wavelength interval radiated radiation flux.
  • Low-pressure gas discharge lamps are Lamps usually with a gas pressure between 10 mbar and 50 mbar, preferably between 20 mbar and 30 mbar operate. Your specific electrical power consumption is considerably lower than with medium pressure and High pressure lamps and ranges between 0.2 and 2.5, preferably between 0.5 and 1.0 watts per centimeter their arc length. Although the low pressure gas discharge lamps an efficiency for the relevant UV range have, which is higher than in the usual lamps and is between 30 and 40%, is the total achieved UV radiation flow significantly lower than with conventional lamps used. It is approximately 0.2 watts per centimeter of arc length and is therefore about a factor 100 smaller than with conventional medium and high pressure lamps.
  • UV-curing printing inks can also be cured satisfactorily with low-pressure gas discharge lamps, even if the printing ink has a UV illuminance of between 1 and 100 mW / cm 2 , preferably between 10 and 50 mW / cm 2 , is irradiated.
  • the UV irradiance of the printing material is approximately 1 W / cm 2 .
  • the irradiance relating to the printing material indicates which radiation flux strikes a surface element of the printing material which is optionally inclined at an angle to the radiation direction.
  • the irradiance has the unit W / cm 2 .
  • the low pressure gas discharge lamp can advantageously in the UV-B or UV-C range lie.
  • a line spectrum refers to this on the wavelength with the highest UV intensity.
  • this relates Indication of the maximum of the spectral radiation flux distribution.
  • this characteristic refers to the Maximum in terms of lines and continuous Emission areas.
  • a low pressure gas discharge lamp whose above a wavelength of 190 nm, spectral integrated above 240 nm in particular UV radiation flux more than 50%, preferably more than 75% their UV radiation flux, especially their UV-C radiation flux, is.
  • the above a wavelength of 190 nm, especially integrated spectral above 240 nm UV-C radiation flux more than 50%, preferably more than 75 % of the UV radiation flux is.
  • a further advantageous feature can be provided be that several low pressure gas discharge lamps with differing emission spectra are used, in particular a combination of a UV-C lamp with a UV-B low-pressure gas discharge lamp.
  • radical hardening Colors also have the advantage that their chemical Composition can vary very widely.
  • the one here most commonly used binders mostly absorb considerable in the UV-C range, so that even when used of photoinitiators absorbing in the UV-C range only low reactivity of the ink can be achieved can.
  • they are cationically curable Printing inks used binders in the UV-C range to a high degree transparent, so that even with a UV-C or UV-B low pressure gas discharge lamp a high Reactivity can be achieved. From the above Reasons are in the context of the invention cationic curing inks based on epoxies preferred. Radically curing colors are also usable.
  • a printing ink is used the printing process according to the invention is cured, their binder component for that of the low pressure gas discharge lamp emitted in the UV-C or UV-B range UV light is highly transparent so that it is deeper Layers still sufficient of UV light can be achieved.
  • the usual layer thicknesses for offset are between 1 and 3 ⁇ m and in flexographic printing between 3 and 8 ⁇ m. Add to that in each case the crimped edges of a maximum of 20 ⁇ m thickness, so that the binder is sufficient up to a thickness of 20 ⁇ m should be transparent.
  • the properties in particular are related of the binder, namely its transparency for what is used UV light, and the reactivity of the binder photoinitiator system significant. Furthermore, how usual, the individual components miscible and with each other be tolerated, i.e. do not trigger spontaneous reactions.
  • the fillers and additives can be in liquid or solid form and are subject to the same Transparency requirements for UV light like the binders.
  • the printing ink should be sufficiently reactive for the UV light and can be activated by this. This is especially true for the photoinitiators used in the Wavelength range should be sufficiently reactive.
  • the Reactivity means two things. On the one hand, the Absorption of UV light must be sufficiently high. On the other hand The photoinitiators should absorb the absorbed energy also respond well to the corresponding radicals (radical Polymerization) or acids (cationic polymerization) to trigger the chain reaction for the polymerization transfer or implement. The photoinitiator should therefore absorb to a sufficiently high degree and more appropriately Concentration. He must also be able to the energy of the absorbed UV light on the monomers transferred to. This applies to both the radical, as well also for cationic hardening.
