the camera setup allows the same camera setup to be used across modules (of

the same type) and systems.

Mask Setup

Mask setup allows you to create a unique named setup that defines what

characters are allowed in each position of a string.

The definition includes a description of the setup, the number of characters

allowed, and what set of characters are allowed at each of the character positions.

For most applications the characters used would be upper case A-Z and 0-9.

To access Mask Setup, select Applications |Global Setups | Mask Setup.

OCR Font Setup

The OCR Font Setup allows the creation of a font that is understood by the OCR

vision tool with a set of characters that is applicable to the user’s needs. This setup

creates the OCR Font Setup file (with extension .xml) and OCR Font files (with

extension .ocr). When adding an OCR element to a card setup the OCR font setup

file is selected as a setting.

The OCR font is created from a Windows TrueType Font (.ttf) file and can be

restricted to contain only the particular characters which are expected to be read

from a card. Restricting the number of characters contained in the font can

increase verification performance by reducing the number of comparisons

needed to interpret a character during the read process.

To access OCR Font Setup select Applications |Global Setups | OCR Font
