An indelible marker is also known as a permanent marker. It can write on almost everything and is permanent on most porous surfaces. Moreover, permanency is not finite and could depend on several things.
What makes a marker indelible lies in the ink ingredients or the type of ink used. The surface and storage condition should also be considered when it comes to permanency.
Indelible markers, on the other hand, are either made with:
- Alcohol-based ink,
- Oil-based ink,
- Pigment-based ink,
- or a combination of these three and other solvents.
Its ink also possesses additional features such as being waterproof, fraud-proof, and lightfastness.
- Waterproof is where writings can resist fading when exposed to water or moisture. It is a key feature for indelible markers used in laboratories and outdoor applications.
- Fraud proof is the capability to resist ink removal from solvent exposure. This feature is specifically important in preventing fraudulent activities such as check washings, alterations of signatures, and other details on important documents.
- Lightfastness is the ability to resist fading upon sun exposure. Dark colors are said to be lightfast than light or bright colors. This is an important feature if you are looking for archival markers that are believed to last for years.
Like other markers, an indelible marker pen is used for various purposes. It is used for writing, drawing, lettering, labeling, self-expression, and many others.
Because of its durability, professionals and many industries prefer to use indelible markers for tagging, engineering surveys, logistics, identification, warehousing, laboratories, documentation, and other purposes.
There are also markers featuring indelible ink for medical purposes; they are indelible marker dental pens.
How Does It Work?
Indelible markers similarly work like other markers. It comes in a barrel that contains the ink and a felt tip that releases the ink.
Its light and its pen-like structure make it easy to apply and control. Like regular markers, they are also available in different tip types: fine tips and chisel tips.
Its application is wide and can be used for plastic and on different surfaces such as paper, wood, metal, glass, stone, ceramics, fabric, leather, and even on skin.
