Bruckmuehl, Germany - A leading European book printing group has now dramatically improved their HP inkjet press performance by putting into commercial operation an adphosNIR^® Photonic drying system to upgrade thier existing HP T360 colour press. The adphosNIR^®-dryer Upgrade fully replaces the existing (original) HP hot-air based unit with HP extended dryer for each printing tower. 

Thanks to the working principle of the adphosNIR^®-technology and the chosen dryer configuration, they can now operate using  regular offset quality substrates which reduces substantially their costs (saving a 3 digit euro amount/per tonne). In addition thanks to the adphosNIR^®-technology and it’s low thermal stress on the substrate, there is much less paper “dry-out” and therefore an equivalent reduction in paper cockle and curl (“waviness”). After dryer replacement, due to the reduced ink penetration into uncoated printed media, a better print quality is possible with higher ink density on the surface, along with more contrast and a more crisp image. 

Finally, an enormous energy savings (50 – 70 %) is found with the adphosNIR^®-dryer operation. As it requires almost no start-up period and as, during non-print operations (stationary web), the adphosNIR^®-dryer switches off, overall it require less than 50% total power consumption compared to the originally installed HP hot air driers. This easily results in a several hundred thousand kWh saving per year and explains the resulting very short payback period (can be less than 12 months). 

The installation of the adphosNIR^®-dryer upgrade takes less than 2 days and can even be done over a weekend in all existing T3xx printing presses.
