Watermark Ink For Offset Printing

Product Description:

1. Before you use the watermark ink, you need to clean the roller and confirm that there is no residue of ink on the roller.
2. We suggest you could use the single-colored printing machine to print the paper.

Product Application:

Watermark inks can be printed in offset, letterpress and flexography; they are used for printing a watermark which will give a certain transparency on a paper, not exceeding 90gsm. As those inks are rather oily, it is advisable to print them on the back side of the paper and to avoid overprinting them.

The effect of transparency will be reach after a period of 24-48 hours, because ink needs that time for a complete migration through the paper. Consequently a coated paper cannot be used.

Letterpress is the best printing process because the watermark ink is push inside of the paper. In addition to our standard version, our range includes fluorescent watermark inks, fluorescent in blue, green and yellow under UV lights. A watermark ink is also available for wet offset, but less efficient.

After you print the watermark ink on the paper, it looks the same effect as the watermark paper. Through the light, you could see the clearly water marked image.
