Toray Graphics Introduces Waterless Offset Printing Plate


The new IMPRIMA LJ plate has been developed for label printers looking for a high quality, high durability water-washable plate that provides printing stability and significant sustainability value.

With printing resolution up to 175 lpi, label printers can be assured of producing even the most demanding jobs with ease. Plus, the IMPRIMA LJ plate is 200% more durable than comparable waterless offset printing plates.

This thermal negative CTP printing plate uses a standard imaging wavelength of 830 nanometres. It is ideal for label production but can also be used for a wide range of other applications, including CD/DVDs, loyalty cards, metal decoration and for printing on non-absorbent substrates.

These plates are also ideal for printers using UV curable inks as well as for sheetfed and on web presses that require production quality such as density stability during the print run. Its high resistance to chemicals and UV inks makes it an extremely durable plate. It also offers ideal screening at 1-99% with 36 micron FM or hybrid screening, and 2-98% with AM screening at 175 lpi.

Since this is a water-washable plate, it requires no chemicals in the developing process, and it can be processed in most available waterless processors. It also does not require post-baking. This makes it easy to insert into any offset workflow and results in low-cost processing.

Other benefits include:

• Stable dot reproduction.
• High ink coverage.
• Up to three hours daylight resistance under standard safe-light conditions.
• Long shelf life, suitable for archiving.
• Compatible with all waterless inks.
• Following these developments, Toray will in the near term introduce a new plate type for other printing segments: the IMPRIMA WJ high resolution and high durability water-washable plate.
