These inks can be printed in offset, letterpress or flexography, they are used to print a watermark which will give a certain transparency to media which do not exceed 90 g/m². As these inks are quite oily, it is recommended to print them on the back of the support and to avoid overprinting afterwards (risk of refusal). On the front any ink can be used.
The maximum effect of the ink will be observed after a period of 24 to 48 hours to allow the ink to “migrate” into the paper. Of course no coated support can be used.
Letterpress remains the best means of printing because the ink is then “pushed” into the support. In addition to the standard version, our range includes UV fluorescent versions in blue, green and yellow. A version usable in wet offset is also available.
