May 23, 2024 (press release) –

SCREEN Graphic Solutions Co., Ltd. (SCREEN GA) has finalized development of the Digital Primer Option for its Truepress LABEL 350UV SAI S UV inkjet printing system. The new option maximizes UV inkjet printing capabilities by significantly improving print quality, adhesion and durability. SCREEN GA plans to launch the ink worldwide starting in October 2024.


In the packaging industry, including the label segment, a wide variety of substrates are used in different regions and for different jobs, and in recent years, due to environmental issues, the number of such substrates has been increasing. Compared to other digital methods, UV inkjet printing is more suitable for wide substrates and is more durable, and its popularity has increased based on these advantages.
However, compared to analog printing with its wide range of ink types, UV inkjet printing may not produce satisfactory results on some special substrates, specified substrates and certain regional substrates. In digital printing, it is also difficult to use multiple ink types, and the wettability varies depending on the ink and substrate, resulting in differences in quality, adhesion and durability.
In response to these trends, SCREEN GA has developed the Digital Primer Option for its Truepress LABEL 350UV SAI S to improve adhesion, graininess and other characteristics. This option utilizes the extra head space in the Truepress LABEL 350UV SAI S to install an inline inkjet primer unit without requiring additional installation space and additional main UV lamps1.
The primer unit can automatically generate a primer layer based on print data. This ability to apply the primer without additional work maximizes the superior usability of digital printing. Furthermore, the ink itself can be a near-transparent color and can be used like a varnish in some cases, making it more decorative and a means of adding value. In this way, the inline primer unit can be used to expand the range of materials and applications for digital printing, increase the digital printing processes, and add value. This creates further cost advantages and contributes to the system’s environmental friendliness by reducing waste and power consumption.
SCREEN GA remains committed to enriching lives and continuing to make the world more colorful through print. This underpins its goal of helping to build a sustainable society and create greater prosperity for its customers and all others worldwide.
