- the combination of the third squeegee and the first squeegee improves and increases the process speed of the device according to the invention.
- the rotating hollow cylindrical screen template can thus be moved faster with a higher turn.
- the pane preferably includes glass panes, more preferably glass panes of different size or dimensioning. Excess or unused color due to the geometry of the disk is transferred to the paint stripping roller via the second squeegee.
- the distance between the screen and the ink removal roller is set so that both rotate independently of each other and at the same time the ink residues can be transferred.
- a feed trough is preferably arranged between the third squeegee and the second squeegee.
- the feed chute allows the transport of excess paint which runs back from the screen within the screen stencil over the second squeegee and can not be transferred to the ink removal roller.
- the second squeegee transfers the color present in sieve meshes to the ink removal roller.

- the ink collected in the ink removal roller can be returned via hoses back into the rotating hollow cylindrical screen template.
- the color removal roller preferably comprises a color scraper.
- the color scraper allows the transfer of the paint located on the color removal roller into the paint collector.
- the ink supply device preferably comprises hoses or nozzles.
- the ink supply device introduces new paint into the rotating hollow cylindrical screen template.
- the ink supply device can also be coupled with the ink collecting container and reuse ink already used. This color feedback lowers the production costs.
- the screen preferably has a hole diameter of 40 ⁇ to 70 ⁇ .
- the individual mesh width depends on the motif to be printed and the composition, viscosity and wetting of the color.
- the color preferably contains stoving paint.
- the stoving paint may preferably be cured on the disc following the bending process following the inking. Alternatively, a separate heating process, preferably at 500 ° C to 800 ° C is possible.

- the paint is applied over the first squeegee through the screen on the disk.
- the (pre-) filling the screen with paint via the third doctor reduces the amount of ink present in the area of the first doctor blade. Larger amounts of ink in the area of the first doctor blade often lead to clumping or smearing on the disk to be printed.
- the disc leaves in the next step, the hollow cylindrical screen template on the treadmill. The remaining ink within the screen is transferred via a second doctor blade to an adjacent rotating paint stripper roller.
- the paint on the disc is preferably baked.
- the baking process improves the stability and durability of the paint.
- the disc is preferably preloaded or partially preloaded.
- the tempering process of the disk is preferably used for baking the paint. The integration of the burn-in process into the tempering process makes a separate burn-in process superfluous and thus saves process energy.
- the treadmill is preferably moved at a speed of 5 m / min to 20 m / min, more preferably 10 m / min to 17 m / min, in particular greater than 30 m / min. This speed allows compared to the prior art, a more cost-efficient printing process at significantly higher cycle times.
- the hollow cylindrical sieve stencil and the ink removal roller preferably rotate in opposite directions.
