Gloss Effect Image Patterns on Recording Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional specialty imaging techniques in printing processes often conflict with aesthetics, particularly in non-rectangular areas of documents, and are not effective with low gloss toners, as they require high gloss materials and can be easily replicated by conventional copiers and scanners.
Innovation Solution
The implementation of a dynamic pattern generation process using standard page description language constructs to create a pattern color space that incorporates specialty imaging features, allowing for the creation of scalable gloss effects without the need for high gloss materials, and enabling the use of low gloss toners while maintaining security against counterfeiting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional specialty imaging techniques are used to provide security measures, then security protection is improved, but aesthetic appeal deteriorates due to rectangular restrictions and non-integration with document design
Solution Approach 1:
The patent applies dynamics by transitioning from static rectangular security elements to dynamic free-form security patterns that can adapt to any document layout. The system allows security features to be placed in arbitrary shapes and positions throughout the document, not confined to rectangular areas, thereby maintaining both security functionality and aesthetic integration with the document design.
Solution Approach 2:
The patent implements local quality by allowing different regions of the document to have customized security patterns tailored to their specific aesthetic and functional requirements. Each area can have security features that match its local design characteristics, rather than applying uniform rectangular security elements throughout the document.
2Reliability
If conventional gloss effect imaging is used to create security features, then security protection is improved, but material requirements worsen due to the need for high gloss materials and specialized printing processes
Solution Approach 1:
The patent applies parameter changes by altering the surface topology parameter of the printed material. Instead of requiring high gloss materials, the system creates microscopic peaks and valleys through specialized halftone patterns that produce gloss effects through geometric light reflection. This changes the controlling parameter from material glossiness to surface geometry, enabling security features with standard toners.
Solution Approach 2:
The patent substitutes the mechanical/material-based gloss creation method with a geometric/optical method. Rather than relying on high gloss materials or specialized printing mechanics, the system uses computational algorithms to generate halftone patterns that create gloss effects through the arrangement of ink dots, replacing material properties with geometric arrangements.
3Reliability
If conventional specialty imaging techniques are used, then security measures are provided, but ease of operation worsens due to restricted design freedom and rectangular area limitations
Solution Approach 1:
The patent applies dynamics by enabling security patterns to be dynamically placed in free-form areas throughout the document rather than being restricted to static rectangular regions. The system can adapt security element shapes and positions to match the document's design flow, making the design process more flexible and intuitive for users.
Solution Approach 2:
The patent implements universality by creating a security imaging system that can operate in any document area and shape, not limited to specific rectangular zones. The free-form security patterns can be applied universally across different document types and layouts, providing both security protection and design flexibility in a single unified approach.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances document security by providing a scalable gloss effect that is difficult to replicate, integrates well with low gloss toners, and maintains aesthetic appeal across various document areas, while preventing counterfeiting without the need for high gloss materials.
Implementation Method 1
a gloss effect which is visible when a relative angle between an observer's viewing angle and an angle of illuminating the recording medium by an illumination source is a predetermined angle
Data Source
AI summary
Gloss effect image patterns are created by creating a solid color background and overprinting the solid color background with the glossmark. In creating the glossmark, a background base of an electronic image region is painted with a solid color corresponding to a color of a marking material; using a first electronic pattern ink, a background of the electronic image region is painted without knocking out the solid color of the background base of the electronic image region; and using a second electronic pattern ink, a foreground in the electronic image region is painted without knocking out the solid color of the background base of the electronic image region such that a pattern in the rendered image area is only visible when a predetermined angle between an observer's viewing angle and an angle of illuminating the rendered recording medium by an illumination source is realized.
