During printing, ink will penetrate deeper into porous media compared to non-porous media. The deeper the ink penetrates into the media, the more difficult it is to fully cure the ink. Un-coated corrugated cardboard is considered to be porous media.
For printing images on porous media with high ink loads the following safety guidelines are recommended:
Use Canon Production Printing recommended profiles. This will help limit the ink load to a safe level. Canon Production Printing recommended profiles can be found at http://www.onyxgfx.com/my-onyx/drivers-and-profiles/
Use “Production” or slower print modes if possible
Set UV lamp power levels to high
Handle printed media with prescribed gloves
Avoid un-coated cardboard media with a high content of recycled materials. Media with a high content of recycled materials will allow ink to penetrate deeper in to the media
NOTE
For printing in “Express” mode the UV lamp power level is fixed at the highest possible level by the printer .
