know what to expect for every character position. In other words, the software can be instructed what to expect:
alpha, numeric, or special characters. This is called “Field masking” and will be explained in detail later. This
module may be used with a monochrome or color camera.
There are many fonts used in the printing industry. This system is designed to learn new fonts as necessary.
Optical Character Verification (OCV)
The human readable characters are verified at very high press speeds. The OCV module ensures that a string of
sequential characters is read and or verified against a known field or database. In other words, you tell the
software what should be there and the software will report if it was actually there. It will also return a percentage
score as to how well it matched to the trained character. This module may be used with a monochrome or color
camera.
Blemish Detection
This software module is capable of detecting a multitude of print faults from skewing and smears to missing
information. These algorithms also include a “variable image data” function which accounts for variable image
data within a pattern-matching zone and does not report them as blemishes. All of this inspecting is completed at
press speed. This module may be used with either a monochrome or color camera.
Barcode 1D and 2D Health Check
This feature is enabled by a

representative. When requested, the system can be configured
for health check instead of grading. If this feature is enabled, the choices are 1D/2D (Read) or (Health check),
instead of 1D/2D (Read) or (Grade). The computer reports a percentage instead of a grade. For example,
instead of 3.4/06/660 (B), the computer reports 85%. The warning and passing scores are shown as
percentages instead of grades. This module may be used with a monochrome or color camera, and any color
combinations of printed barcodes.
Delta E
The Delta E Color Detection module detects color variations by comparing the trained color (also called the
Golden color) to the image color currently displayed in the field of view.
The Delta E module continuously calculates the average L*a*b* values of all the pixels within a sector according
to CIE 2000 specifications. This module must be used with a color camera only.
