Waterproof ink is a type of ink that is resistant to water damage. It is often used for writing or drawing on surfaces that may come into contact with water, such as maps, architectural drawings, and marine charts. Waterproof ink is also used in some types of pens, markers, and printers.
Indian ink is a type of ink that is made from a mixture of carbon black, water, and shellac. It is commonly used for drawing and calligraphy. Indian ink is not waterproof, but it is water-resistant, meaning that it does not smudge or run easily when exposed to water.
The main difference between waterproof ink and Indian ink is their water resistance. Waterproof ink is resistant to water damage, while Indian ink is water-resistant. Waterproof ink is also more permanent than Indian ink, meaning that it is less likely to fade or deteriorate over time.
Here is a table that summarizes the key differences between waterproof ink and Indian ink:
| Feature | Waterproof Ink | Indian Ink |
|---|---|---|
| Water resistance | Waterproof | Water-resistant |
| Permanence | More permanent | Less permanent |
| Uses | Writing or drawing on surfaces that may come into contact with water, maps, architectural drawings, marine charts | Drawing and calligraphy |
