Thermal printer paper

Thermal paper is a different type of paper than your normal printer paper. It is printed on with heat, not ink. There are advantages to it, such as it’s economical benefit, it’s great reliability, flexibility of size, it comes in BPA free rolls (no toxins in the paper), it comes in 8 ½ x 11 (standard size), and no limit to sheets. The parts There are multiple parts to thermal printer paper. They are as follows. 1. Base paper a. This paper is what holds the chemicals, and is the sturdy structure of the paper. 2. The Under-coating a. This is to ensure a smooth look for the paper, and with which to hold the thermal coating. The smoother this coating is, the better quality the image. 3. The Thermal-coating a. This is the coating which, made of a vast amount of chemical compounds, creates an image when put under heat. How it works The thermal paper crosses over the thermal print head. The thermal coating turns black (or red if used with 2-toned printer and paper) in the heated areas. Two colors can be printed (see above). Each color that is available runs across the print head at a different temperature. Acetone on Thermal paper This video shows some cool effects with acetone on the thermal coating. Reading the comments will explain in brief detail the experiments people have done, and some of the chemistry involved.
