The PC-Scan LD4 incorporates a Software package and a measuring device (Laser Device). The Laser Device has a built in measuring unit with a diode red light laser driven by a motor. Measurement are transferred to the Software for evaluation.

The evaluation is divided into two parts. One part according to ISO/IEC 15416 (ANSI) the other part according to Symbology specifications and/or standards. In case of EAN Codes the international Standard ISO/IEC 15420 is the reference for the traditional evaluation.

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 quality requirement according to the application or material characteristics.

The traditional evaluation gives detailed metric results, bar width and positions as extreme and average values direct on the screen. In a table detail values for each bar and space.

As well as printed codes the PC-Scan/LD4 is able to measure positive and negative Film Masters according to ISO/IEC 15421.

PC-Scan/LD4 – Technical Specifications and Options

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 color contrast evaluation in preprint or to evaluate unreadable bar codes.

Film 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 bar codes on circular bodies like cans, bottles and beakers. A defined position is required for measuring. Bar code have to be printed in ladder form on curved surfaces.

Basic Models

The measuring unit of the PC-Scan/LD4 (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.
