Other Printing Matter TRIZ Cases
- Electronic Greeting Card With Embedded Multimedia Player
Embedding a universal multimedia player inside the card structure resolves the trade-off between content versatility and device complexity.
- Security Document Lenticular Grid for Tamper-Resistant Verification
Offset image element grids behind a rear lenticular lens grid filter visual data by viewing angle, preventing unauthorized manipulation of stored information.
- Passport Data Page Security Features for Tamper Detection
Security features extending from the data page into the binding flap reveal visible offsets when manipulated, preventing undetected extraction.
- Composition Book Perforation Geometry for Consistent Page Removal
Varying perforation distances from sheet centerlines compensate for folding geometry, eliminating size variation when removing pages for binder use.
- Transfer Film with Complementary Relief Structure for Optical Clarity
A transfer film uses a carrier with a master relief structure to deposit a complementary microstructure onto a surface layer.
- Optically Variable Laser Marking on Plastic Security Articles
Sequential low and high power laser passes generate angle-dependent optical effects, preventing photocopy reproduction of plastic security features.
- Elastomeric Polymer Spine Bond for Passport Booklet Flatness
An elastomeric polymer adhesive joins passport data pages and security laminates along the gutter edges, reducing restoring force to keep the booklet flat open.
- Cutting Substrate Alignment via Longitudinal Mark Discontinuities
Optical units detect discontinuities in longitudinal cutting marks to activate transverse mark detection for precise substrate alignment.
