The Gallus Screeny Advanced Line (A-Line) sets new standards

As an OEM, Gallus has always been committed to delivering the highest standards in terms of quality, safety, performance, reliability, responsibility and technological advances for its Gallus Screeny Genuine screen printing plates.

This Gallus promise is also reflected in the new Gallus Screeny Advanced Line (A-Line). Due to be released on the market from beginning of 2015, it draws on the Gallus Screeny S-Line in terms of ink layer thickness and print resolution.

Reinventing the screen printing plate

For the Gallus Screeny A-Line, the complete architecture of the screen printing plate – from the micro-mesh structure to the photopolymer layer – was examined to ensure it fulfilled as many of the criteria for a good screen printing plate as possible. In simpler terms, the combined Gallus expertise gathered over 30 years of developing and producing screen printing plates was used to reinvent such plates.

The results are impressive:

• Optimised combination of tried-and-tested and new raw materials
• Improvement and perfection of manufacturing processes

The ongoing optimisation of the production workflow for screen printing plates and many years of experience in materials development have improved the products significantly. The diagram below shows the evolution of the Gallus Screeny Genuine screen printing plates, from the Gallus Screeny Standard Line and Gallus Screeny S-Line to the Gallus Screeny A-Line. All the screen printing plates have been designed in such a way that each improved generation is able to deliver greater productivity for the same applications, as all previous generations.

Criteria for a good screen printing plate

Robustness, excellent print results, optimum image resolution, a wide range of possible applications, a perfect ink flow, high print speed and straightforward final checking of the imaged screen printing plate are important factors that have been taken into account during the development of the Gallus Screeny A-Line. By fulfilling these criteria, the Gallus Screeny A-Line sets entirely new standards for screen printing on the label market.

• Extreme robustness

The main feature of the Gallus Screeny A-Line is its exceptional robustness, which is particularly advantageous when handling screen printing plates both inside and outside the press. This robustness greatly simplifies handling in prepress and production. The excellent basic stability of the Gallus Screeny A-Line minimises the risk of damage to the screen printing cylinder, thus lengthening the cylinder’s service life.

• Low overall costs per label thanks to simple handling and maximised re-utilisation rate

Manufacturing the screen cylinder, transporting it to the press, its frequent installation in and removal from the press, and its cleaning and storage are all made much easier. The Gallus Screeny A-Line is therefore ideal for maximising the number of times plates can be re-used. This higher re-utilisation rate is also the quickest way to significantly cut costs per screen-printed label.
The more often the same screen printing plate can be used for repeat jobs with the identical print image, the lower the “total price” for the screen cylinder and the lower the total costs per label.

• Simple final checking of imaged screen printing plate

The Gallus Screeny A-Line has a new, violet-coloured photopolymer layer that provides a perfect contrast for the human eye. In yellow light, it is now even easier for prepress employees to judge whether the screen printing plate is correctly imaged and if the polymer layer has been washed out perfectly. The final check of the fabric prior to printing is of crucial importance. If the screen printing plate hasn’t been perfectly imaged and washed out, this will lead to waste in the print shops’ production halls. Only a carefully prepared screen printing plate can deliver the best possible print results, optimised image resolution and perfect ink flow.
