Substrate coated with a substance which turns black in the immediate areas when heat is applied.
Direct thermal is a printing technology method in which the printer utilizes a paper that reacts chemically to heat. The label rolls are coated with a thermo-sensitive layer that darkens when exposed to intense heat. Direct thermal printers require no ink or ribbon and are typically used when a bar code label needs to endure for a year or less.
Direct thermal printing utilizes a heat sensitive chemically coated paper. The thermal print head is typically a long linear array of tiny resistive heating elements (about 100 to 300 per inch) that are arranged perpendicular to the paper flow. Each thermal print head element locally heats an area on the chemically coated paper directly under the print element. This induces a chemical reaction, which causes a black dot to form in that area. Building it from dot rows as the media passes underneath the active edge of the print head forms the image.
Imprinting process using heated pins to strike specially coated paper to produce an image.
The printing method that uses a chemically coated heat sensitive media. Once the heat from the thermal printhead is applied to the media the media turns black thus imaging on the media.
A process in which a set of pins on a printhead are selectively heated onto heat-sensitive paper (or label stock). In turn, the paper turns dark and a bar code is formed. Over time, a Direct Thermal image will eventually fade. Also known as Thermal Printing.
A specially coated label material that contains microscopic capsules of ink, which burst when exposed to heat. Direct Thermal material is made to allow scanning in either of two light spectrums: visible light or infrared. Direct Thermal labels are ideal for short applications where the label is not required to last more than 6-8 months.
Printing method utilising heat impinged upon a specially coated substrate so the heat turns the surface selectively black. A simple test to establish whether a substrate is direct thermal image or not, is to light a match and hold it near the substrate, close enough to discolour but not burn. A light bulb should produce the same effect.
The printing method that uses chemically coated heat sensitive media. Once the heat from the thermal printhead is applied the media changes colour (usually black) producing an image.
A specialized printing technology using rapidly heated pins that selectively activate a heat sensitive coating applied to the facestock thus forming the desired image.
A method of thermal printing in which images are printed when heat from the thermal printhead produces a black mark on the media.
