A number of competing technologies have emerged, each with its own characteristics, and among these, thermal printing has progressed from providing primarily a utility function confined to special paper for calculators or portable terminals, to a much wider range of applications and capabilities. Today's market offerings range from low cost, quiet, home printers using a transfer ribbon to provide solid black or colour printing on selected smooth bond-like paper, to machines capable of printing several pages a minute at densities of 200 per inch and higher.

  • Thermal Transfer Vs. Direct Thermal: Five Key Considerations
    Thermal Transfer vs. Direct Thermal: Five Key Considerations BY SATO America Direct thermal label printing has traditionally been a niche Knowing the difference between thermal transfer printing and technology used across several narrow vertical markets including direct thermal printing is only the first step in evaluating the two meat, poultry and dairy. However, developments in thermal paper alternative technologies for use in a company’s label printing technology have resulted in a broader range of products that are application. The following considerations, while not an exhaustive now suitable for use in many applications across nearly any vertical list, account for the key areas of review during the technology market. The result has been increased interest in direct thermal as evaluation stage. the technology choice for new or upgraded applications. THERMAL PRINTHEAD LIFE & COST First, what’s the basic difference between direct thermal printing and thermal transfer printing? In simplest terms, thermal transfer From the above comparison, note that direct thermal printing printing utilizes a thermal ribbon and direct thermal printing does requires the printhead elements be in direct contact with the label not. Thermal transfer involves the thermal printhead elements material as it is pulled across the printhead. Conversely, thermal (dots) heating the backside of a thermal transfer ribbon to melt transfer printing has thermal ribbon acting as a “buffer” between and transfer the compounds on the front side of the ribbon to the the printhead elements and the label material. Many thermal label material, thus creating the printed image. Direct thermal ribbons are designed with a back-coating that serves to increase printing requires a heat sensitive label material.

  • Examination of Photocopies and Computer Print Outs
    Examination of photocopies and computer print outs Surbhi Mathur Assistant Professor Gujarat Forensic Sciences University What is a photocopy???? • It is a copy of usually written or printed material made with a process in which an image is formed by the action of light usually on an electrically charged surface. Contd…. • It is also called xerography, which was derived from two Greek words “xeros” , meaning dry and “graphos” , meaning writing. • Xerography was invented in the late 1930s by an American patent lawyer named Chester Carlson. It is a printing and photocopying technique that works on the basis of electrostatic charges. How does photocopier machine works??? • To produce photocopies of an original document, the photocopy machine first makes a temporary image, a sort of negative of the original. • Inside the machine is cylinder or drum made of a highly conductive metal, usually aluminum, coated with a photoconductive, often selenium. Contd…. • The surface of the drum is then charged using LED or laser light source. • The printed area of the original document will form positive charge on the drum, forming a latent image of the printed matter. Contd…. • The charge on the image area is used to attract the negative toner particles to make the image visible on the drum surface. • A stronger electrical charge of the same type is given to the paper. This causes toner to transfer from drum to paper. Contd…. • The toner is adhered or fixed to the paper by heat and pressure. • A lamp or hot roller melts the toner, which is absorbed into the paper. Handling of photocopied documents • Photocopied exhibits should be stored in paper folders not plastic.

    Thermal vs. Inkjet Printing Why thermal technology? Why inkjet printers are not mobile? • Low running costs: No ink or toner, the cost per page will remain • Recommended uses of inkjet technology are generally limited to the same regardless of how much print is on the page. a home or office environment. • Reliable: Thermal print technology is inherently reliable – • Inkjet printers are known to have problems in mobile using a very limited number of moving parts and operating under a environments where temperature or pressure extremes occur. wide range of environmental conditions. Cold ink or pressure variations can upset the printing process impacting print quality. • Print quality: Thermal technology uses precise temperature and contact with the paper to place a pixel (printed dot) onto a page. • The nozzles used in inkjet printers may become easily clogged in This means precise placement of every dot producing high print the extreme environments required for mobile printing. quality character and graphic images. • The many moving parts of the printer cannot withstand the harsh • Easy to maintain: There are no consumables such as ink, toners or use of mobile users. drums to replenish.
