Case history

Aluminium printing

This section, illustrates the result of an aluminium printing test carried out on a flexographic rotary printer, with colour black, on opaque Amcor at 130 m/min..
The sample tests show two completely opposite results: the UV Ray print is perfectly dry while the competitor’s one, when placed in contact with a sheet, releases almost all the ink due to poor anchorage to the media.
In the images, you can see the tests on the UV Ray samples and on those of the competition right after the printing:

IMMAGINE
UV Ray: the ink is perfectly polymerised and anchored.

IMMAGINE
Competition: the ink has no anchorage and sticks to the back of the reel.

Temperatures on intermittent
This section, on the other hand, indicates the temperatures measured on an intermittent KBA.
Through an international-brand infrared heat camera, the differences were recorded at various speeds and powers, compared to a competitor’s system:

  Power Linear speed Step Temperature °C
UV Ray 30 5    40,3
Competition minimum 5    87,4 + additional fan to cool down the media
UV Ray 50 5  35,7
Competition minimum 5  61,0
UV Ray 50 5  68,4
Competition minimum 5  94,7
UV Ray 50 15    35,3
UV Ray 60 15    35,3

IMMAGINE
UV Ray: 50W at 5 m/min, measured 68.4 °C.

IMMAGINE
Competition: minimum power a 5 m/min, measured 94.7 °C.
