Choosing an inappropri ate scanning aperture will result in i naccurate quality measures. Too small an aperture may det ect reflectance nonuniformities (spots and voids) that would not affect scannin g with a “normal” aperture size. Too larg e an aperture will not be able to resolve i ndividual elements of the symbol.

In 1982 the American National Standards Institute, (ANSI) X3A1 Techn ical Subcommittee with the assistance of other ANSI and indust ry committees and bar code authorities, began studying the i ssu e of bar code print quality in other symbologies for all types of printing methods.
Numeric ranges exist within the alphabetic gr ades. Use of the numeric equivalents may provide great er assistance in determining symbol pro blems. The following illustration shows a Scan Re flectance Profile from a Quick Check ® PC scan of a symbol.
The lowest reflectance value for at leas t one bar (Rmin) mu st be half or less than the highest reflectance value for a space (R max). For example, if the highest space reflectance value is equal to 80%, t he reflectanc e value of at least one bar in the profile must be 40% or less.
A ≥ 70% B ≥ 60% C ≥ 50% D ≥ 40% F < 40% Defects are voids (light areas) found in the bars or spots (dark areas) found in the spaces and quiet zones of the code. According to the ISO/IEC print quality guideline, each eleme nt is individually evaluat ed for its reflectance non- uniformity.
PC, the symbol will fail Decode even if all other parameters pass. Deco de is a Pass/Fail parameter. The Scan Grade is the lowest grade receive d out of the eight parameters tested from a given scan profile.
common corrective actions that can be attempted to remedy symbol qual ity problems. Problem: Low Symbol Contrast (SC) or PCS Possible Causes: • High Minimum Reflectance (Rmin) • Bars too “light” • Incorrect verification light source • Low Maximum Reflectance (Rmax) • Dark substrate Potential Solutions: • Darken bars, i.
Possible Causes: • Small X dimension (<0.10”) makes narr ow spaces appear too narrow. • Verifier aperture too large Potential Solutions: • Make narrow spaces slightly wider than narr ow bars (if possible). • Check for proper verifier aperture size (see W and/Mouse Aperture Selection Table on page 21 .
• Too fast, too slow, too variable • Practice scanning smoothly, with little pressure on the wa nd. • Practice scanning the symbol, outsi de of Quiet Zone to outside of Quiet Zone in about one-half secon d. Scanner Missing, Scanner Disable d • The software is unable to detect the presenc e of a wand.
Parts of a Bar Code Symbol Each symbology has its own characteristi cs. Basic charact eristics of bar code symbologies are: • The number of element widths. • Two-width symbologies have only two eleme nt widths (wide and narrow). Codabar, Code 39, and Interleaved 2-of-5 are two-width symbologies.
• Whether there is a required check di git or character for the symbology, Check digits/characters help ensure that symbol data is correctly entered into the computer system.
The Quick Check ® PC provides a quick and comprehens ive basis for a bar code quality program. Setting up a bar code quality program req uires an understanding of the requirements of a given applic ation, wh ether for in-house use or to satisfy customer requests.
Glossary of Terms achieved width: The actual element width based on measurements. algorithm: A set of steps guaranteed to effect a desired result by virtue of mathematical proof.
