Screen GP Australia has introduced a new high opacity white mode that offers more opaque white for the Truepress Jet L350UV SAI S, the specialised UV inkjet label printing system developed, manufactured and distributed by Screen.
White ink is most commonly applied as a base layer on coloured, metallic or clear stocks. In these applications, white ink is printed first, followed by cyan, magenta, yellow and black (and special colour) inks on top. In these instances, the white ink is used to overcome the colour, or translucency, of the substrate, providing a white background or base. On clear substrates and clear bottles, white is necessary to prevent light from passing through and washing out and affecting other colours.
As digital has permeated the label sector, both the volume and value of digital printing shipments in the label printing market have shown consistent annual increases. The growth rate of digitally-printed labels has been particularly strong, when compared to shipment volumes, demonstrating the high added value offered by digital printing.
There has also been special interest in labels that reflect consumers’ desires to buy specific products, including those promoting local production for local consumption and limited-time campaigns, as well as original designs that may involve variable content.
These trends have in turn led to a growing number of situations in which high-quality items such as ‘prime labels’ are required. However, if a bottle or package’s contents, for example, are darkly coloured, the colour may show through a label, affecting the impact of its design. This has become a point of concern for printing companies seeking higher quality where fundamentally translucent media is concerned.
In response to this growing need, Screen has launched a high-opacity white mode as an option for its Truepress Jet L350UV SAI S digital label press. When used with clear film or similar labels, this new printing mode provides more opaque white, preventing the colour of bottles or package contents, from showing through. This helps to maintain rich colour saturation, ensuring high-quality labels with eye-catching visual appeal, even when applied to translucent base materials.
The liquor, cosmetics and toiletry industries are increasingly employing UV inkjet-based digital printing as a substitute for silk-screen printing. Digital printing provides these industries with a number of advantages, including shorter turnaround times, lower costs and reduced environmental impact, and demand is expected to grow consistently going forward.
Screen has a long history of developing inkjet printing technologies that offer both high speed and high quality, and has also worked to promote production line automation and create a range of solutions to resolve specific customer needs. By combining these various aspects, Screen hopes to open up further new markets and contribute to the continuing growth of the overall label printing industry.
The high-opacity white mode is available as a retrofit to existing Screen Truepress Jet L350 SAI installations, or as an inclusion in new installations.
Screen L350UV SAI presses are sold through partner Jet Technologies in Australia and New Zealand.
