Tresu offers expanded chamber doctor blades, ink supply systems

Tresu Group is presenting an expanded range of chamber doctor blades and supply systems for automating ink flow in label and package printing at Labelexpo Europe 2019.

The company will also provide information about its strengthened customer care program that helps flexo printers to maximize machine time, and customized retrofittable flexo units for integration with narrow-web coating and printing lines.

Tresu chamber doctor blade systems, in widths from 185mm to 6,000mm, feature patented rubber seals, controlling pressure while preventing leakage and air contamination – enabling clean blister-free print with fast drying characteristics and improved gloss values at faster print speeds. Chambers are available in carbon fiber form, featuring light weight and optimum corrosion resistance, while ceramic and aluminum alternatives are also available for various applications. 

The Tresu FlexiPrint Reservoir Saveink chamber, for widths up to 800mm wide, includes an optimized reservoir, needing no connected pump. Ink may be added without press stoppages.

Also exhibited will be Tresus’s new carbon fiber D3P chamber for paperboard and flexible packaging flexo applications. The chamber provides clean doctoring when working with anilox roll diameters that are common with these applications, and features a smooth ink-repellent internal surface. These features enable controlled ink flow and thus consistent quality prints, at speeds of up to 800m/min.    

Made with a single component and featuring a pneumatic fast blade-change clamping system, the D3P is claimed to offer superior strength to withstand high printing speeds, and lighter weights than aluminum alternatives, resulting in easier handling, contributing to faster set-up times. 

Tresu supply systems automatically control flow, pressure level and color density to provide consistent print quality without air contamination, and thorough, fast, simultaneous chamber-cleaning. As part of the automatic cleaning, a high proportion of the unused ink can be returned to the bucket, resulting in significant long-term ink savings. The chambers can be retrofitted as an upgrade of existing equipment. Tresu’s F10 iCon ink supply system regulates ink flow, pressure and viscosity, maintaining constant ink density values. It performs automatic ink changes, including chamber cleaning and ink returns in minutes, saving time and materials.

Furthermore, Tresu has strengthened its Customer Care program that provides ancillary and machine customers with a comprehensive, ongoing support package to maximize machine uptime and assure consistent quality. Services provided include 24/7 support, machine and equipment upgrades, life cycle management, proactive diagnostics to boost performance, and a fast supply of consumable products and spare parts, optionally through an enhanced webshop.  

Henrik Kristensen, vice-president, Tresu ancillary and customer care, commented: ‘Faster delivery times, customization and stringent quality standards are now the norm in label and packaging supply chains. Tresu’s program of ancillary and retrofittable flexo systems, backed up with comprehensive global customer care, provides the flexo printer with a firm basis for automating processes, reducing setup times, eliminating waste and assuring predictable, repeatable results.’
