IMPORTANT: The LVS-7500 External System is designed to inspect labels, record and display
the results, and supply optional signals to the printer or other external system. The LVS-7500
External System cannot “stop”, “score out void” or “reprint” labels; these are functions that are
the responsibility of the printer. Be sure your printer has these necessary capabilities and
interface connections to utilize the output capabilities of the LVS-7500 External System.
Optical Character Recognition (OCR)
Unlike the OCV Module, this module “reads” characters and reports the data content. This data is typically
variable and the content remains unknown until it is read. It is important to note that the system can be trained to
know what to expect for every character position. In other words, the software can be programmed on what
characters to expect: alpha, numeric, or special characters. Many fonts are used in the printing industry. The
LVS-7500 External System is designed to learn new fonts as necessary.
IMPORTANT: The LVS-7500 External System does not distinguish between
touching/overlapping characters; thus, characters must not touch or overlap. The LVS-7500
External System reads and/or verifies uppercase characters only.
Optical Character Verification (OCV)
The OCV module verifies human readable characters at unparalleled speeds at point sizes as low as four printer
points (one printer point is defined as 1/72
nd
of an inch or .35 mm). The LVS-7500 External System OCV module
ensures that a string of sequential alpha-numeric characters is verified against a known field or database. In
other words, you program the software to detect what characters should appear and the software reports if the
characters actually appeared. The software will also return a percentage score as to how well the character(s)
matched to the trained character(s).
IMPORTANT: The LVS-7500 External System does not distinguish between
touching/overlapping characters; thus, characters must not touch or overlap. The LVS-7500
External System reads and/or verifies uppercase characters only.
Number Validation
Verifies the expected order of any numerical series, detects duplicates and sequence errors, and matches
variable numbers with external data files.
Data and Code Matching
Verifies encoded data that represents human readable information and ensures synchronicity of multiple fields
within a label.
