Information on Barcodes Generators & Scanners

Barcode labels are the tags that help both humans and machines to identify any given product. These labels come in several types and resemble the average tags. These labels are differentiated by the type of base material, called stock, that they are printed on. Labels are currently available in all types of materials and come with a variety of adhesive backings. They can also be ordered in several customized shapes and sizes.

Apart from the basic types of barcodes labels, labels can also be categorized into three main forms: aluminum barcode labels, polyester barcode labels, and ceramic barcode labels. The aluminum labels are very durable, usually with an image on the surface that lasts for a long time, even in the harshest of climatic conditions. It can withstand wear and tear, heat, cold, chemicals and abrasion. The polyester barcode label has an image imbedded in the underside of the plastic material. It uses a permanent industrial adhesive bonding and is known for its dependability. However, the last word in durability is the ceramic barcode label. It is made up of a stainless steel base and coated with ceramic. These labels can withstand strong acids or very high temperatures.

Barcode labels can be further subdivided into the following categories: resin-coated paper barcode labels, paper barcode labels, long-range retro-reflective barcode labels, and floor labels. Resin-coated paper barcode labels are the most common labels used in the official work. These labels are created with the help of tough resin coating for durability. Paper barcode labels are very economical and ideal for tracking of documents.

A long-range retro-reflective barcode label is another case in point. These labels are normally hung from a wall or a ceiling. Made of rigid metal or plastic, these labels provide maximum functionality for long-range scanners. Lastly, we have floor labels. These labels are used in industrial floors and are developed using steel and are then coated with urethane. These labels can withstand heavy vehicular traffic.

With barcode labels forming an intrinsic part of the daily human existence, they are finding an increasing utility in the day to day life. Newer forms of labels are being designed by the day.

Barcode Printers come in various types, including general-purpose laser and inkjet printers. Then there are printers that support multiple symbologies. They are called Thermal bar code label printers. General-purpose laser and inkjet printers cannot directly print barcodes. That is because these basic printers do not support bar code symbologies and are therefore upgraded to do so. They need to be programmed to support bar coding, which may entail addition of more features and fonts.

Barcode printers employ two major printing methods, namely Direct Thermal and Thermal Transfer. Both methods basically involve the same technique to print bar codes with difference in the use of ribbon. They make use of a print-head that applies heat to a surface that is pre-marked. Heated ribbon is used to produce long-lasting images in Thermal Transfer printing, while Direct Thermal does not use ribbon and instead prints the image directly on the label. In Thermal Transfer printing, a large number of materials may be used. This generally helps in creating durable images over a long period of time. Direct Thermal, on the other hand, helps in making put-away labels, receipts and other such small variety.

Ideally, barcode printers can print on labels that are specifically designed for the purpose. However, the printers are also capable of printing on fabrics like polyester. We have printers etching away prints on headbands and even synthetic materials. Quite contrary to popular perception, barcodes are not only black. Barcode printers can print in various colors, but black is generally preferred because a light color may end up with insufficient contrast between the bars resulting in unreadable barcodes.

Nowadays, several security features are available to ensure that there is no counterfeit coding by the printers. The latest thermal printers are capable of printing smart labels that contain radio frequency identification chips within the label media. These smart features go a long way in plugging any loopholes in barcode printing and provide a guarantee of authentication.
