Thermal fax paper

Technology Each area of application follows its own rules and sets its own requirements. Whether labels or receipts at POS, lottery tickets or admission tickets, bank statements, travel tickets or ECG printouts. Mitsubishi has the right thermal paper for the job.

Thermal fax paper

History[ edit ] The earliest Thermal fax paper thermal papers were developed by NCR Corporation using dye chemistry and 3M using metallic salts.

The NCR technology became the market leader over time, although the image would fade rather rapidly compared with the much more expensive, but durable 3M technology.

Texas Instruments invented the thermal print head inand the Silenta computer terminal with a thermal printer, was released in the market in The Silent was the first thermal print system that printed on thermal paper. During the s, Hewlett-Packard integrated thermal paper printers into the design of its Thermal fax paper series desktop computers, and integrated it into the top of the series CRT terminals as well as in plotters.

In the s and early s, Japanese producers such as RicohJujo, and Kanzakiusing similar dye-based chemistryformed partnerships with barcode printer manufacturers such as TEC, Sato, and others and entered the emerging global bar code industry, primarily in supermarkets.

Leading pressure-sensitive label producers such as Avery Dennison became major consumers of direct thermal paper for label applications. In the late s and early s, thermal transferlaser printingelectrophotographyand, to a lesser extent, ink jet printing began to take away industrial and warehouse barcode applications due to better durability.

Direct thermal made a strong comeback with point of sale receipts gasoline pumps, cash registers, rental car receipts, etc. DuringNintendo used thermal paper technology for their Game Boy Printer.

Chemistry[ edit ] Four different types of imaging chemicals are used in thermally sensitive papers: A third widely used leuco dye is Crystal violet lactone. Red or magenta color can be achieved with dyes such as Yamamoto Red Yellow can be produced by the protonation of a triaryl pyridine, such as Copikem Yellow These dyes have a colorless leuco form when crystalline or when in a pH neutral environment, but become colored when dissolved in a melt and exposed to an acidic environment.

Developers[ edit ] Leuco dyes, in general, provide little color when melted unless they are melted in conjunction with one or more organic acids. Zinc salts of substituted salicylic acids, such as zinc di-tert-butylsalicylate have also been commercially used as developers.

Sensitizers[ edit ] A leuco dye and a developer, when melted together, are enough to produce color. However, the thermal threshold of the coated layer containing the colorizing components is determined by the lowest melting component of the layer.

Furthermore, developers and leuco dyes often mix poorly upon melting. To optimize the colorization temperature and to facilitate mixing, a third chemical called a sensitizer is commonly added to the imaging layer. Sensitizers are commonly simple ether molecules such as 1,2-bis- 3-methylphenoxy ethane or 2-benzyloxynapthalene.

These two materials melt at approximately C, which is a practical lower limit for thermal coloration. These low-cost ethers are excellent low viscosity solvents for leuco dyes and developers, and this facilitates color formation at a well-defined temperature and with minimum energy input.

Stabilizers[ edit ] Dyes in thermally sensitive paper are often unstable and return to their original colorless, crystalline forms when stored in hot or humid conditions. Stabilizers often share similarities with developers and are often complex multifunctional phenols that inhibit recrystallization of the dye and developer, thereby stabilizing the printed image.

Zink[ edit ] In the early s, Polaroid developed the Zink "zero-ink" technology. It has several layers: Zink technology allows the printing of full-color images in a single pass without requiring ink cartridges. The color addressing is achieved by controlling the heat pulse length and intensity.

These dyes form microcrystals of their colorless tautomerswhich convert to the colored form by melting and retain color after resolidification.Set your store and be able to check inventory and pick up at your local store. Fax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single.
