Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gloss marks, a form of holographic watermark, are challenging to reproduce accurately due to compatibility issues with emulsion aggregation toner and require specialized high-end printers, which are expensive and not widely available, limiting their use in security printing.
Innovation Solution
A method involving adjusting RGB color values for pattern inks, applying geometric patterns, and manipulating these patterns on top of features to create a gloss effect, which can be printed on various media types using standard printers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If gloss marks are created using traditional methods with specialized high-end printers, then the gloss effect quality is improved, but the device cost and complexity increase significantly
Solution Approach 1:
The patent applies the copying principle by creating a digital representation of the gloss mark effect that can be reproduced on standard printers. Instead of requiring specialized hardware, the invention uses software-based pattern generation that mimics the appearance of traditional gloss marks, allowing the effect to be copied across different printing devices without needing the original specialized equipment.
Solution Approach 2:
The patent employs parameter changes by modifying RGB color values for pattern inks and adjusting geometric pattern parameters to create the gloss effect. By changing these digital parameters, the invention achieves variable gloss effects that can be adapted to different printers and media types, resolving the contradiction between effect quality and device requirements.
2Reliability
If gloss marks are produced using specialized high-end printers, then the security feature reliability is improved, but the ease of manufacture and accessibility deteriorate
Solution Approach 1:
The patent applies universality by designing a gloss mark creation method that works across multiple printer types and media formats. The geometric pattern-based approach with adjustable parameters allows the same software solution to function on standard office printers, production printers, and various media types, making the security feature universally applicable rather than limited to specialized equipment.
Solution Approach 2:
The patent utilizes standard, widely available printers rather than expensive specialized equipment. By replacing high-cost dedicated gloss mark printers with common multifunction devices, the invention makes security features accessible to organizations without large budgets, trading the longevity of specialized equipment for immediate accessibility and cost-effectiveness.
3Reliability
If traditional gloss mark methods are used, then the anti-counterfeiting effectiveness is improved, but the cost of implementation increases
Solution Approach 1:
The patent creates a cost-effective copy of the gloss mark effect using digital pattern generation rather than expensive physical application processes. By rendering geometric patterns that simulate gloss effects through software and standard printing, the invention reproduces the anti-counterfeiting functionality without requiring costly specialized materials or equipment.
Solution Approach 2:
The patent reduces implementation cost by using adjustable RGB color values and geometric pattern parameters that can be optimized for different printing conditions. This flexibility allows the same base technology to work across various price points of printers and media, eliminating the need to invest in expensive specialized equipment while maintaining anti-counterfeiting effectiveness.

AI summary
Methods and systems for creating a gloss effect, can involve adjusting a color selected with a first RGB color value for a first pattern ink among a group of pattern inks to appear lighter and selecting a common geometric pattern for the group of pattern inks including the first pattern ink and a second pattern ink. A feature can be written with an object with a second RGB color value and a geometric pattern can be written opaquely on top of the selected common geometric pattern. The feature can be erased within the object with a third RGB color value. The feature can be then written with a fourth RGB color value. The geometric pattern can be then written opaquely on top of the feature in the color adjusted selected for the first pattern ink to create a gloss effect with the geometric pattern opaquely on top of the feature in the color adjusted selected for the first pattern ink which displays the feature.
