Thermographic Printing
Thermographic printing refers to two types of printing, both of which rely on heat to create the letters or images on a sheet of paper. The simplest type of thermography is where the paper has been coated with a material that changes colour on heating. This is called thermal printing and was used in older model fax machines and is used in most shop till receipt printers. This is called direct thermal. More complex is thermal transfer printing that melts print off a ribbon and onto the sheet of paper. Thermography as raised print process Thermography is also the name of a post print process that is achieved today using traditional printing methods coupled with thermography machines. Thermography machines consist of three sections with a through conveyor. The first section applies thermographic/embossing powder, made from plastic resins, to the substrate (normally paper). The areas selected for raised printing are printed with slow-drying inks that do not contain dryers or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printing
Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century.Shelagh Vainker in Anne Farrer (ed), "Caves of the Thousand Buddhas", 1990, British Museum publications, Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.

Thermal Printer
Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by passing paper with a thermochromic coating, commonly known as thermal paper, over a print head consisting of tiny electrically heated elements. The coating turns black in the areas where it is heated, producing an image. Most thermal printers are monochrome (black and white) although some two-color designs exist. Grayscale is usually rasterized because it can only be adjusted by temperature control. Thermal-transfer printing is a different method, using plain paper with a heat-sensitive ribbon instead of heat-sensitive paper, but using similar print heads. Thermal transfer printer require the use of wax-based ribbons that adhere to the substrate during the printing process. As a result, users must load both labels and ribbon, essentially using an alternative ink system. Design A thermal printer typically contains at least these components: * Thermal head: Prod ...

Fax Machine
Fax (short for facsimile), sometimes called telecopying or telefax (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 device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines transmit an audio-encoded digital representation of the page, using data compression to transmit areas that are all-white or all-black, more quickly. Initially a niche product, fax machines became ubiquitous in offices in the 1980s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cash Register
A cash register, sometimes called a till or automated money handling system, is a mechanical or electronic device for registering and calculating transactions at a point of sale. It is usually attached to a Cash register#Cash drawer, drawer for storing cash and other valuables. A modern cash register is usually attached to a printer that can print out receipts for record-keeping purposes. History An early mechanical cash register was invented by James Ritty and John Birch following the American Civil War. James was the owner of a Bar (establishment), saloon in Dayton, Ohio, Dayton, Ohio, US, and wanted to stop employees from pilfering his profits. The Ritty Model I was invented in 1879 after seeing a tool that counted the revolutions of the propeller on a steamship. With the help of James' brother John Ritty, they patented it in 1879. It was called ''Ritty's Incorruptible Cashier'' and it was invented to stop cashiers from pilfering and eliminate employee theft and embezzlemen ...

Receipt
A receipt (also known as a packing list, packing slip, packaging slip, (delivery) docket, shipping list, delivery list, bill of the parcel, Manifest (transportation), manifest, or customer receipt) is a document acknowledging that something has been received, such as money or property in payment following a sale or other transfer of goods or provision of a service. All receipts must have the date of purchase on them. If the recipient of the payment is legally required to collect sales tax or Value-added tax, VAT from the customer, the amount would be added to the receipt, and the collection would be deemed to have been on behalf of the relevant tax authority. In many countries, a retailer is required to include the sales tax or VAT in the displayed price of goods sold, from which the tax amount would be calculated at the point of sale and remitted to the tax authorities in due course. Similarly, amounts may be deducted from amounts payable, as in the case of Withholding tax, ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Transfer Printer
Thermal-transfer printing is a digital printing method in which material is applied to paper (or some other material) by melting a coating of ribbon so that it stays glued to the material on which the print is applied. It contrasts with direct thermal printing, where no ribbon is present in the process. Thermal transfer is preferred over direct thermal printing on surfaces that are heat-sensitive or when higher durability of printed matter (especially against heat) is desired. Thermal transfer is a popular print process particularly used for the printing of identification labels. It is the most widely used printing process in the world for the printing of high-quality barcodes. Printers like label makers can laminate the print for added durability. Thermal transfer printing was invented by SATO corporation. The world's first thermal-transfer label printer SATO M-2311 was produced in 1981.

Fahrenheit
The Fahrenheit scale () is a scale of temperature, temperature scale based on one proposed in 1724 by the German-Polish physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a Salt (chemistry), salt). The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F (about 2.6 °F less than the modern value due to a later redefinition of the scale). For much of the 20th century, the Fahrenheit scale was defined by two fixed points with a 180 °F separation: the temperature at which pure water freezes was defined as 32 °F and the boiling point of water was defined to be 212 °F, b ...

Celsius
The degree Celsius is the unit of temperature on the Celsius temperature scale "Celsius temperature scale, also called centigrade temperature scale, scale based on 0 ° for the melting point of water and 100 ° for the boiling point of water at 1 atm pressure." (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the closely related Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific point on the Celsius temperature scale or to a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who proposed the first version of it in 1742. The unit was called ''centigrade'' in several languages (from the Latin ''centum'', which means 100, and ''gradus'', which means steps) for many years. In 1948, the International Committee for Weights and Measures renamed it to honor Celsius and also to rem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diploma
A diploma is a document awarded by an educational institution (such as a college or university) testifying the recipient has graduated by successfully completing their courses of studies. Historically, it has also referred to a charter or official document of diplomacy. The diploma (as a document certifying a qualification) may also be called a ''testamur'', Latin for "we testify" or "certify" (testari), so called from the word with which the certificate begins; this is commonly used in Australia to refer to the document certifying the award of a degree. Alternatively, this document can simply be referred to as a degree certificate or graduation certificate, or as a ''parchment''. The certificate that a Nobel laureate receives is also called a diploma. The term diploma is also used in some historical contexts, to refer to documents signed by a monarch affirming a grant or tenure of specified land and its conditions (see Anglo-Saxon charters and diplomatics).

Paper Embossing
Embossing and debossing are the processes of creating either raised or recessed relief images and designs in paper and other materials. An embossed pattern is raised against the background, while a debossed pattern is sunken into the surface of the material but might protrude somewhat on the reverse side. Techniques Often used in combination with foil stamping, embossing alters the surface of paper stock or other substrates by providing a three-dimensional or raised effect on selected areas. The procedure requires the use of two dies: one that is raised and one that is recessed. The dies fit into each other so that when the paper is pressed between them, the raised die forces the stock into the recessed die and creates the embossed impression. A specific level of pressure is applied to the dies in order to squeeze the fibers of the paper, which results in a permanently raised area in the paper. When the dies are produced, a die maker engraves the desired image into several m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dye Sublimation
Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage. This understanding of the process was later shown to be incorrect, as there is some liquefication of the dye. Since then, the process has become properly known as dye diffusion, though this technically correct term has not supplanted the original name. Chemical technology in Printing and Imaging Systems, ed. J A G Drake, 1993, pp 73-85 Historically, "dye sublimation" referred to page printers that use a thermal printhead to transfer dye from a ribbon directly onto the print media via sublimation. While it originally was used in creating prepress proofs, today this technology survives in ID card printers and dedicated photo printers, ofte ...
