How does the screen printing transfer work?
In screen printing transfer, the screen print is not printed directly on the substrate, but beforehand on a special transfer paper. Once the motif is printed on the transfer paper, it is sprinkled with a fine adhesive granulate and then dried for several minutes through a drying channel. The excess granules lying next to the ink on the transfer paper are to be blown away in the machine outlet with a blower.
How can excess granules be safely removed?
Contact and separation of doctor blade, screen and substrate can cause all materials involved to become electrostatically charged. The granules may also already be electrostatically charged on delContact and separation of doctor blade, screen and substrate can cause all materials involved to become electrostatically charged. The granules may also already be electrostatically charged on delivery. The granules also adhere next to the printed areas of the transfer paper due to the electrostatic charge of the materials involved in the printing process. The excess granules cannot be completely removed with a conventional blower. This results in customer complaints due to quality defects.
The electrostatically charged materials must be discharged without contact using ionizers suitable for the application. In order to successfully discharge the product, it is necessary to install the ionizers in a physically ideal position.
