Koehler Paper has announced that Blue4est® Pro eco-friendly linerless labels have been successfully certified for Toshiba Tec Singapore’s all-in-one printer TRST-L1. Blue4est® Pro is the innovative follow-up to the popular Blue4est® thermal paper for cash register. Linerless labels do have various advantages, including waste reduction and cost efficiency.
Linerless labels free of chemical developers
Just like conventional Blue4est® POS paper, Blue4est® Pro is guaranteed to be free of chemical developers and can be used with normal thermal printers. Instead of a chemical reaction to heat, Blue4est® thermal paper uses a purely physical mechanism for its printing results. Tiny bubbles in the functional layer collapse when subjected to heat from the thermal printhead, which results in the black layer underneath becoming visible. Moreover, Blue4est® Pro features an additional layer that protects the paper from mechanical damage for use as label stock. Converted to linerless labels without release liner, Blue4est® Pro is a sustainable and cost-efficient solution as it reduces waste and provides more flexibility.
Comprehensive paper tests successfully completed
Intensive paper tests have been run in Singapore in different climatic environments over several months with linerless labels made from the new eco-friendly Blue4est® Pro thermal paper as well as the traditional KT 72 TC PF phenol-free thermal paper. Different criteria have been applied to simulate intensive use on the new TRST-L1. Sebastian Früh, Director Thermal Paper Division at Koehler Paper, states: “We have tested different applications with our high-quality thermal paper on Toshiba Tec Sin-gapore’s new all-in-one linerless printer, including print accuracy for texts, printing of graphics and logos, or barcode readability. It came out that our eco-friendly Blue4est® Pro as well as our topcoated phenol-free thermal paper work very well as linerless labels and are a perfect match with Toshiba Tec Singapore’s new all-in-one printer.” Toshiba Tec Singapore will add Koehler Paper’s Blue4est® Pro and KT 72 TC PF phenol-free thermal paper to the printer user guide for their all-in-one TRST-L1 from now on. “The linerless printers are designed to deliver outstanding reliability and adaptability across a wide range of industries,” said Louisse Lim, Assistant General Manager of Business Development at Toshiba Tec Singapore.“ With the TRST-L1’s innovative dual-orientation functionality, businesses can seamlessly integrate our solutions into their operations while staying agile in a rapidly changing landscape. Our partnership with Koehler Paper marks an exciting step forward in providing customers with greater performance, improved efficiency, and more sustainable printing solutions.”
