SWY-1001 Screen-Printing Black Watermark Ink is a solvent-volatile drying type anti-counterfeiting ink, specially formulated for screen printing applications. Visually opaque in appearance, it presents a pale off-white color to the naked eye, yet reveals a distinct grey-black watermark effect when held up to light—mimicking the characteristic look of watermarked paper.
 
Featuring easy visual authentication without the need for specialized detection equipment, this ink is widely applied in the security printing of books, periodicals, negotiable instruments, and various official documents.

.SWY-1001 Screen-Printing Black Watermark Ink is a solvent-based volatile drying ink, compatible with most screen printing machines available on the market. Air drying is the recommended curing method; oven drying may compromise the watermark effect to some extent.
SWY-1001 Screen-Printing Black Watermark Ink features fine particles and high viscosity. Stir thoroughly before use, or dilute it with 5%–10% of solvents such as 783 or DBE prior to printing. A screen with 300–350 mesh count is generally recommended for application.
This ink is typically printed between two layers of laminated paper. For single-side paper substrates, it is advisable to print on the reverse side of the paper with a screen of 350–420 mesh count. To achieve an effect closer to that of watermarked paper, apply a screen ruling of 30–50 lines to the pattern.
Before official machine printing with SWY-1001 Screen-Printing Black Watermark Ink, adjust all printing parameters—including screen mesh count, squeegee angle, printing pressure, ink viscosity, and drying time—according to the printing substrate and pattern. Conduct a small-batch test beforehand.
For optimal watermark performance, this ink should be applied to paper with a grammage of less than 80 g/m².
SWY-1001 Screen-Printing Black Watermark Ink is not weather-resistant, acid-alkali resistant, or high-temperature resistant. Avoid using it in high-temperature or outdoor environments as much as possible.
