Seesaw Gloss Effect Printing via Surface Finish Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional specialty imaging techniques in printing processes often require special inks or materials and are limited in aesthetics, particularly in non-rectangular areas, and struggle to provide dynamic security features that cannot be replicated by conventional copiers or scanners.
Innovation Solution
The development of a specialty imaging technique using standard page description language constructs to create a pattern color space that incorporates dynamic security features, such as color-shifting effects, without the need for special inks, and can be applied to variable data, enabling real-time image-based specialty imaging that uses the print job image as 'paint' to create scalable gloss effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional specialty imaging techniques are used to provide security measures, then fraud protection is improved, but the document aesthetics and design freedom deteriorate due to rectangular area restrictions
Solution Approach 1:
The patent applies dynamics by creating a seesaw gloss effect that changes appearance based on viewing angle. The security element transitions between different visual states (glossy vs. matte appearance) depending on the observer's position, allowing the same element to provide both security functionality and aesthetic flexibility in various document layouts.
Solution Approach 2:
The patent applies local quality by creating different surface properties within the same security element. One portion of the element has a gloss-mark appearance while another has a matte appearance, allowing the element to adapt to different design contexts and provide both security and aesthetic value in varied locations within the document.
2Reliability
If specialty imaging techniques are used to provide dynamic security features, then security against counterfeiting is improved, but the complexity of the printing process and materials required increases
Solution Approach 1:
The patent applies parameter changes by utilizing the gloss-mark effect where the appearance of the printed element changes based on viewing angle parameters. This allows dynamic security features to be achieved through standard printing processes by manipulating the physical state of the printed material rather than requiring complex special inks or multi-step printing procedures.
3Reliability
If conventional security elements are added to documents, then anti-counterfeiting measures are improved, but the space available for other document content decreases
Solution Approach 1:
The patent applies universality by creating security elements that serve multiple functions. The seesaw gloss effect elements provide both security protection and aesthetic appeal, allowing them to be integrated into various document areas without requiring separate dedicated security zones, thus preserving space for other document content.

AI summary
A system and method render see-saw scalable gloss effect image patterns on a recording medium by using to two colors to provide one region with a relatively smooth surface, while a second region has a relatively rougher surface. A third region is added composed of a color different than the first two, wherein the third region has a relatively smooth surface where it intersects with the first region and a relatively rougher surface where it intersects with the second region. As the rendered recording medium is tilted at different angles, the image patterns thereon toggle to create a see-saw effect.
