Thermal paper, and methods and systems for forming the same

A sheet for thermal printing, the sheet comprising:

• a first layer comprising:
• a sheet material dyed in a specific color;
• a second layer coextensive with the first layer and comprising a plurality of discrete particles randomly and evenly arranged per a thickness unit and per an area unit of the second layer, the particles being at least partly transmissive to light in the visible light range;
• and
• a third layer coextensive with the second layer and comprising a plurality of discrete particles evenly arranged per a thickness unit and per an area unit of the third layer, the discrete particles of the third layer being at least partly transmissive to light in the visible light range, wherein the discrete particles of the second layer have a melting temperature that is different from a melting temperature of the discrete particles of the third layer.
