e-Join Delved into the Subdivision Field of Medical Image Output and Entered the "Specialized, Exquisite and Innovative" Thermal Printing Solution

Thermal printing is a non-impact method of creating images on paper and synthetic film. The process applies heat from a thermal printhead onto thermal material. The base material used in the thermal printing process may be selected from a variety of paper grades or synthetic films (e.g. PP, PE, or PET) with a special chemical coating applied to one side to make it sensitive to heat.

The technology uses the printing head to heat the thermal printing material, which makes the chemical reaction of the material sandwiczed in the substrate coating to create a clear image. It has the advantages of fast speed, low noise and clear printing, and is more environmentally friendly than laser and inkjet printing technology. e-Join (Hong Kong) Technology Co., LTD., located in Hong Kong, China, pioneered the research and development of thermal printing method, and has been widely used in the field of medical image printing and output, becoming one of the manufacturers in the world with both thermal medical dry imager and large-scale production capacity of thermal medical dry film.

In 2011, the R&D team of "e-Join Technology" studied various products and technologies at that time, and completed the breakthrough of circuit board from 2 layers to 8 layers. The control technology core was upgraded from single chip microcomputer to ARM and FPGA, and a number of patents were obtained. The electronic temperature controller is used to control the temperature of the print head, which makes the temperature control more accurate, the preheating time is short, the image uniformity is better, and the printing efficiency is higher.

Thermal printing has a number of important advantages over traditional printing processes; it is fast, clean, quiet, reliable and easy to maintain. There are a limited number of mechanical parts, no messy ribbons or toners, and no inking devices are needed to create the image.

Since thermal printers only have one or two moving components, they are very reliable and economical to operate, and maintenance costs are extremely low. The entire system is compact, simple to operate and suitable for use in virtually all applications.

Thermal printheads are usually much smaller and lighter than the printing elements used by other imaging processes, so thermal printers are suitable when compact size, portability and on-demand printing are needed. At the same time, a sharp and precise image of excellent quality is produced consistently and quickly by properly matching the thermal paper to the printhead by varying the chemical coating formulation.

In recent years, microprocessors have been installed to control printhead operation with major improvements in image sharpness and clarity. A thermal printhead has a large number of tiny resistors, which individually react to convert an electrical impulse into heat. The heat from the printhead on thermal material creates a reaction with the chemical coating to produce an image. The image is produced within milliseconds of contact and is normally black in color. The depth and range of colors may be produced by varying the chemical formulation applied to the base material.

The quality and performance of thermal printing depends heavily on the careful matching of thermal material to printhead equipment specification. As a result, a range of thermal materials is used across a wide spectrum of thermal printers for different applications. To give the required physical characteristics and properties, the type of base material - paper, board, or synthetic film - varies from application to application, as does the thickness and weight of various base materials.

The end result is a specialized high-tech product with thermal characteristics and properties compatible with the thermal printing system in its specific printing application. The end product also possesses the physical and product characteristics and properties essential to the very application itself, (which are typically stiffness, durability, tear-resistance, water-resistance and other similar performance criteria.)
