Inks are water soluble inks.
Once the ink has dried, it becomes waterproof. Fast-drying KB Inks actually shrink as they dry, producing very sharp, clean impressions. All KB colors and blacks are compatible with laser printers. The heat produced by today's laser printers has no effect on them, unlike varnish inks and thermography. More than 50 stock colors and blacks are available, as well as any special matched colors.
