Bundle Processing on APPS
APPS uses optical character recognition (OCR) technology to read both OEL and address block information to sort the mail
Current read rates for OEL bundles is around 80%
Read failures occur due to:
– The address block is obscured by opaque strapping material
– The address block is obscured by opaque shrink wrap
– The OCR fails to correctly decode the OEL

Image Capture
Gray Scale Image – 5,807Kb
Binary Image – 201Kb
OCR decodes Binary Image

Clear Strapping Examples
Strap flush with surface Strap spaced away from surface

Federal Register Notice
Recommends placing the address label in one of the four corners of the mailpiece
Where the label WILL be covered - Proposed DMM Changes
Clear strapping (less than 70% haze)
Clear shrinkwrap (less than 70% haze)
An optional bundle label:
Includes the OEL, the words “OPTIONAL BUNDLE LABEL”, and the City, State, and ZIP Code

OCR Decoding Challenge
APPS OCR Result
Mis-segmented Characters, not Identified as “*”
“SORT” read as “SORF” Due to touching “*”

Future OEL improvements
These are NOT in the proposed DMM changes
Add a bar code to the package and / or OEL label
Use of OCR-friendly fonts for OEL data
Add redundant single-character indication of OEL type
Eliminate dashes ( - ) in OEL, which can appear to touch when printed poorly
Separate fill characters with spaces, to eliminate near-touching
