    User Interface Illumination Icons Direct Part Mark (DPM) verifiers have multiple lighting options to grade according to various grading methodologies and standards (such as AIM-DPM). When verifying using ISO15415, only the 45Q lighting option is available for selection; when verifying using ISO 29158 (AIM-DPM), all lighting options are available for selection. Note: Some lighting options are not allowed in some application standards so you should only select options that provide you with a result that is valid for your application.

    Settings Settings Accessing the Settings Menu To access Settings, select the Settings icon in the upper left hand corner of the interface. Application Settings The contents of the settings window will depend upon the Application Standard that you select. This is because the application standard automatically selects many parameters.
  • Page 28 Settings The GS1 Application standard allows barcodes to be verified according to GS1 General Specifications. GS1 General Specifications contain several categories of applications which are described in its Tables 1-11. You can select from among these tables to specify the application category for your barcodes. For example, if you are printing for point of sale (POS) applications, Table 1 is applicable to your barcodes.
  • Page 29 Settings MIL-130-STD UID This application standard will properly report the quality standard used to grade the code and the data structure used in (Construct 1 or Construct 2) for UID marks specified in MIL-STD 130. The MIL-STD spells out what grades are acceptable and requirements for data format.
  • Page 30 Settings UDI/HIBC This application standard checks symbols that meet UDI requirements using either GS1 or HIBCC guidelines. You must specify either ISO 15415 grading or ISO 29158 grading. You may select Dot Peen if it is applicable. Since the data content required for UDI compliance varies depending upon the medical device, only the data format (but not what content is present or missing) is validated.
  • Page 31 Settings Data Parsing and Validation Grading Standard: For any Application Standard selected, a choice must be made for to use either ISO 15415 or ISO 29158 (AIM-DPM) depending on your application. ISO 15415: Reports and displays according to ISO/IEC 15415 which is typically used for label based barcodes. ISO 29158 (AIM-DPM): Select this if you want to utilize the AIM-DPM verification standard.
  • Page 32 Settings ISO/IEC 15434: This option checks data for many industry standards which encode information using ISO/IEC 15434 data structures. These barcodes generally begin with the sequence )]><RS>nn<GS> where nn are two digits which are typically 05, 06 or 12. MIL-STD 130 and some shipping container applications use this formatting style Dot Peen: Use this option for barcodes created with the dot peening process, which is a process where dots are peened onto a...

    Grading Standards and their Parameters AG (Average Grade of Damage across many parts of the Finder Pattern): This is a grade that considers the accumulated effect of damage to several parts of the finder pattern. Five values are averaged together. One of these is the lowest of all the grades associated with all the clock track segments, namely TCT, TTR, TQZ and RCT, RTR, RQZ.

    Grading Standards and their Parameters All of the Fixed Pattern Damage grading (other than AG shown above) are not renamed, but are functionally different since the global threshold and modulation grading scale are different. In general, symbols will obtain a significantly higher grade according to AIM-DPM than ISO 15415.
