Reusing screens is one of the most effective ways to cut costs in screen printing, and it's influenced by the following factors: matching the technical properties of the screen printing plate to the specific application, handling the screen printing cylinder in the printing press, and handling the screen printing cylinder outside the printing press. By controlling these influencing factors, high reuse rates can be achieved, thereby significantly reducing the "cost per screen printing label."
It is extremely important to select the right screen printing plate with the correct technical properties for the respective printing task: Gallus Screeny screen printing plates consist of nickel-plated steel mesh onto which a photopolymer layer is applied by machine with maximum precision. Depending on the combination of mesh structure, wire thickness, galvanized nickel layer, thickness, and adhesion of the photopolymer layer, different reuse rates are achieved for the various screen printing plate types. The extremely comprehensive range of Gallus Screeny screen printing plates with different technical properties meets all printing and economic requirements.

Every print job places individual demands on a screen printing plate. For print jobs where the print image is likely to change, lower reuse rates are perfectly acceptable. Gallus Screeny Standard, for example, is very well suited as a screen printing plate type for this purpose. On the other hand, Gallus Screeny S-Line is recommended for labels that are reproduced several times without changes, as it is significantly more stable than the standard generation.
Gallus Screeny Taktil also often achieves very high repeat rates: on the one hand, the tactile symbols and areas in the print image hardly change, and on the other hand, Gallus Screeny Taktil screen printing plates are coated with a thick photopolymer layer, which gives the screen printing plate an additional photopolymer armor.
The Gallus Screeny Digital varieties are based on the S-Line and Taktil technology, which is why the same high economic reuse rates can be achieved here too.

The handling of the screen cylinder in the printing press is another important factor in achieving a high reuse rate for the screens. The type-specific installation and removal of the cylinder in the screen printing unit, the optimal adjustment of all printing parameters in relation to the print job, the best possible adjustment of the squeegee, etc. are all process steps and details that influence the service life of the printing screens. The more often production employees practice these process steps in their daily work, the more experienced they become. However, if screen printing is a finishing process that is rarely used in everyday production, these steps should be practiced from time to time. Our Gallus Screeny Service & Support Team will be happy to help you with this.

The reuse rate of the screen cylinders outside the printing press is determined by various process steps, which Gallus has automated in order to achieve higher reuse rates.
If, for example, the screen cylinder is cleaned manually by an employee, there is a risk of damage during the cleaning process. However, this can be significantly reduced by automating the cleaning process. In order to achieve the highest possible reuse rate for the screen cylinders, the purchase of a screen cylinder cleaning device, such as that offered by Gallus (ID no. GL.0177400/00), is essential once a certain number of screen printing jobs have been completed in production. Storing screen cylinders with glued screen rings is also an economically sensible decision, as this prevents the screen cylinder from being damaged when the screen rings are removed.
Regardless of how many screen printing jobs you handle in your production, there is nothing stopping you from starting to reuse screens today and significantly reducing your costs per screen-printed label. Gallus Screeny Support will be happy to help you with this decision, with selecting the right screen printing plate for your application, and with training on how to handle the screen cylinder inside and outside the printing press.
