REA PC-Scan LD3

Verify Printed Bar Code Symbols or Film Masters

The REA PC-Scan LD3 system incorporates a copy of TransWin32 software for use with a PC and a measuring device (Laser Device). The Laser Device has a built in measuring unit with a solid state red light laser driven by a motor. Measurements are transferred to the software for evaluation. The evaluation is divided into two parts. One part according to ISO/IEC 15416 (CEN or ANSI evaluation) the other part according to Symbology specifications and/or standards. In case of EAN Codes ISO/IEC 15420 (traditional evaluation)

Software Controlled

Against the standards and specifications measured values are presented clearly on the screen.

The screen shows the two evaluation methods at the same time. ISO/IEC 15416 method evaluates in detail the reflectance profile with different aspects. Quality is presented in 5 steps. The user is able to preset a minimum quality requirement for a 'pass' according to the application or printed material characteristics. The traditional evaluation gives detailed metric results, bar width and positions as extreme and average values direct on the screen. Detail values for each bar and space can be shown in a separate table. As well as printed codes the REA PC-Scan is able to measure positive and negative Film Masters according to ISO/IEC 15421.

Optional Codes: This software has optional extra symbologies. The measuring program is also included in this package. Unknown Codes or random samples can be measured by the measuring program. This is useful for colour contrast evaluation in preprint or to evaluate unreadable barcodes.

Film Master Platen: The Film platen has a 1 cm slit instead of the 3 cm slit in the standard platen. A positive and negative Film Master is included for calibration purposes.

Adaptor for Curved Surfaces: This option is a special bottom plate prism. This supports the measurement of barcodes on circular bodies like cans, bottles and beakers. A defined position is required for measuring. Bar codes have to be printed in ladder format on curved surfaces.

Models: The measuring unit of the REA PC-Scan (Laser Device) is available in four different models. Two different red light wave lengths - either 670 or 635 nm - and two different measuring widths, either 155 mm or 240 mm.
