- Provides a raised area for visual and textured results.
- High transparency.
- Good flexibility at high film weights.
- Exhibits good lay with a smooth finish.
- Fast for cure.
- Viscosity suited to printing via a letterpress duct or rotary screen.
- LA161 offers good adhesion on a range of substrates.
Technical Specification
| Viscosity | 1100 – 1400 cps at 25 °C |
| Volume Recommendations | 10.0 g/m² |
Application
For letterpress the best results are achieved by running the letterpress roller train as open as possible.
When running on screen units the optimum mesh types are as follows:
- Gallus – BT or BZ will result in a printed ink film thickness of approximately 280μm
- Stork – RM 75 40% will result in a printed ink film thickness of approximately 260μm. (This can enable a height of 0.5mm to be achieved)
Substrates
This ink system has been purposely designed for use on many papers, boards, synthetics and foils both supported and unsupported. The inks are press ready and the use of performance additives is not recommended without prior consultation or recommendation by ALDUS INKS. This ink system is not suitable for thermal active papers without the use of a suitable over varnish.
NB. Due to the wide variety of synthetic substrates available we cannot provide guarantees for ink adhesion. We recommend the use of good quality top coated substrates. Non - top coated substrates can also be converted providing the material is corona treated or primed prior to printing.
It is recommended that adequate testing be carried out prior to production runs.
Overprinting
This product is not suited to direct overprinting using thermal transfer, hot foil or laser.
Other Information
All products must be mixed/stirred thoroughly to ensure consistency prior to printing, failure to do so may alter the performance or finish of the ink.
This product can be used for indirect food packaging applications without the presence of an absolute barrier, such as glass or metal as part of the final packaging construction.
