Dry erase markers come in a wide range of colors and are usually sold with a special dry erase eraser. These markers are temporary on a white board, but permanent on paper. A standard set has four colors: red, black, blue and green. Their most common use is in office meeting rooms and lecture halls. The use of a whiteboard replaces a traditional blackboard, which requires the use of chalk.
There are dry erase markers available now in a rainbow of colors, and they can have different types of tips, ranging from chisel to fine tip. The original markers have a chemical odor that can be difficult for people with environmental sensitivities. These markers are now available in low-odor, fruity scents, and with erasers attached to the back of each marker. The eraser tip is an important development, as there is no other tool that allows for precision erasing of writing on a whiteboard.
The ink used for dry erase markers has a combination of pigments and release agents. It is these agents that stop the pigment particles from sticking to the whiteboard and other non-porous surfaces. The ink is a combination of pigment, release agents and chemical solvent. Although these markers are non-toxic, the pigment will stain clothes and skin.
The markers are not affected by water and do not generate any dust. They are thicker than chalk, and easier to use for people with mobility issues in their hands. Less pressure is required with a dry erase marker and the writing surface is easily cleaned without the need for additional pressure.
Whiteboards are the ideal writing material for dry erase markers. They are designed to allow maximum flexibility. They often have a series of linear dots to help the writer align their text for easy reading. Whiteboards have a slightly static-charged surface that helps the pigment to adhere to the surface.
It is important to only use dry erase markers on a whiteboard. The tip can become damaged if used on regular paper or other surfaces and may have to be replaced. Remember to consider the lighting of the room and the location of your audience when using a whiteboard. If the color is too light and the audience is not close by, they may have difficulty seeing the text due to the color contrast between the marker and the whiteboard.
