Drawing inks are available in various compositions adapted to the respective drawing surface media (paper, foil etc). For technical drawing purposes, black drawing inks are predominantly used.
Their special properties are:
• high-contrast
• fast-drying
• water-resistant
• erasure-proof against lead pencil erasers (free of abrasive material)
• lightfast
• can be used in reprography
In addition to the above, colour inks and foil inks as well as etching inks for uncoated glass-clear foils are available.
