Recently, while reading a magazine I noticed ink on my fingers. Why is this happening?
Mar 28, 2018

The ink that was used to print that magazine has poor squalene oil resistance. Squalene oil is human skin oil and is softening or dissolving the ink. Fingerprinting that appears on high gloss UV coatings is caused by squalene oil. Cold set inks have little or no dryer and the ink is absorbed into the uncoated stock and can smear when rubbed.
