Frequently asked questions
Is the marking invisible in daylight?
The blue ink is clear and cannot be seen in daylight. The green ink is milky white and visible as a white marking in daylight. Test on the original material whether the marking is a problem there.
Is the marking water-resistant?
On absorbent surfaces such as textiles, yes. The blue ink is not water-resistant on smooth surfaces – there it is water-soluble. Please check in your own test whether the marking withstands washing or further processing.
What makes the marking visible?
A UV lamp (UV-A, black light). The blue ink is excited in the range of approx. 350–380 nm.
