Pattern Printing TRIZ Cases

Microstructured indentations on a lamination body allow printed ink to penetrate into the recesses, preventing counterfeiting in decentralized production.

A QR code graphic manufacturing device adjusts gray-scaled values and applies error diffusion to generate hidden graphics.

Modified color elements encroach on adjacent pixels in a laser-sensitive matrix, creating asymmetric patterns that guarantee origin and prevent counterfeiting.

Segmenting a braille body into gloss and matte ink layers resolves the trade-off between layer thickness and surface smoothness.

Segmented cavities on a printing roller control adhesive volume and thickness, eliminating material waste from uniform application and subsequent cutting.

Selective deposition of high-viscosity printing material onto relief structure elevations creates precise microstructures.

Direct coating eliminates heavy plastic substrates and precise alignment, reducing production complexity for 3D displays.

Segmented micromirrors present shifting motifs to resolve the trade-off between limited mirror count and required brightness in anti-counterfeiting designs.

Multi-layer data carrier uses laser-modified printing ink to create visible motif images, resolving forgery security challenges.
