2 Dimensional (2D) Bar Codes

A machine readable symbol of rows of encrypted data arranged in a rectangular or square pattern. Can store large amounts of text, numbers, extended & Unicode® characters or photos, making them a much better option for very large amounts of data storage.


Alphanumeric

Character set that consists of upper and lower case letters, numbers 0 through 9 and characters such as the dollar sign, plus, minus, period, comma and other special characters.


Bar Code

A series of black bars and light spaces that are used to represent letters and/or numbers. The bars have varying width and arrangements in order to represent different characters.


Ceramic Marked

Imaged ceramic label applied and fired. Extremely durable and will not lose weight over time.


Code 39

If you are making a general-purpose system that needs to read only numbers and uppercase letters, you can use Code 39. A variable length, bi-directional, self-checking, alpha-numeric linear bar code. It contains 0 through 9, capital letters A through Z, minus symbol, plus symbol, forward slash, space, decimal point, dollar sign and percent symbol. Each character is encoded by 9 bars, 3 of which are always wide.


Code 128

For general-purpose use, Code 128 is usually the best choice. A variable length, bi-directional, continuous, self-checking, alphanumeric linear bar code. Characters in Code 128 consist of 3 bars and 3 spaces with a total character width of 11 modules. It can encode the full 128 character set.


Data Matrix

A very space-efficient 2D symbology that uses a unique perimeter pattern that helps the scanner determine cell locations. The cells are made up of square modules. It can encode letters, numbers, text, bytes of data, extended characters, unicode characters and photos.


Flexographic Marked

Ink based static printing and label converting.


Interleaved 2 of 5

For barcoding numbers only, use Interleaved 2 of 5. This symbology has the flexibility to encode any even number of digits. A continuous, self-checking, numeric symbology linear bar code. It consists only of the numeric values 0 through 9.


Laser Etched

Direct product marking using a high powered laser to burn away the surface coating on a product.


Linear Bar Codes

Black and white vertical bars located on the side of the container. Contains various amounts of data ranging from simple number chains to large amounts of numeric and alphanumeric data sets.


Photo Imaging Marked

Ultra high-density graphically perfect images.


Symbology

Term used to describe how information is encoded into the physical attributes of the bars and spaces. It is the set of rules for a particular type of bar code; analogous to language.


Thermal Marked

Ribbon based printing 200-600 dpi. Pressure sensitive labels capable of holding up at - 196°C and exposure to various chemicals including DMSO, methanol, isopropyl alcohol, etc.


Bar Code Formats

• Pressure Sensitive Labels: A pressure sensitive label that consists of a label substrate and adhesive designed to form a bond with a smooth surface and hold securely at room temperature.

• Laser: Permanent bar code is laser etched directly onto the product.

• Ceramic: Bar code is applied to a ceramic label, then the product is fired. Extremely durable and will not lose weight over time. Ideal in environments with strong caustics, acids or temperature extremes.

• Photo Imaging: Ultra high-density, graphically perfect images are applied to the product.

• Flexographic: Bar code printing using flexible printing plates made of rubber or plastic. The inked plates with a slightly raised image are rotated on a cylinder that transfers the image to the substrate. Flexography uses fast-drying inks. It is a high-speed print process that can print on many types of absorbent and non-absorbent materials and can print continuous patterns.

• Digital: Bar code is produced using full process color 1800 dpi, variable data printing.

• Laser: Direct product marked

• Photo Imaging: Ultra high-density, graphically perfect images applied directly to product

• Flexographic: Ink based static printing and label converting, fast drying inks

• Digital: Full process color 1800 dpi, variable data
