Clear Toner Marking for Variable Data Jobs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for rendering marks on substrates, such as watermarks or authenticating marks, often interfere with the readability of content due to their appearance, especially when a colored toner layer is used beneath the content layer, and there is a need for a system to create a generally transparent mark that is easily identifiable during casual inspection.
Innovation Solution
A method and system for forming a variable data job using clear toner, where original image data is converted to a clear channel color plane, and then merged with variable image data to create a print job that includes a clear toner mark with a glossy appearance, allowing the mark to be observable without visual aids and not interfering with the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a light application of monochrome ink or toner is used to create a watermark mark, then the mark becomes detectable under casual inspection, but the mark appears washed out and may still interfere with content readability
Solution Approach 1:
The patent applies color changes by using clear toner instead of monochrome toner to form the watermark mark. The clear toner contains pigment particles that reflect light differently than the substrate, creating a visible mark through optical property changes rather than color application. This allows the mark to be detectable under casual inspection while maintaining transparency and not interfering with underlying content.
Solution Approach 2:
The patent changes the optical parameters of the mark by using clear toner with specific reflective properties. The clear toner particles have different light reflection characteristics compared to the substrate, creating a visible contrast through parameter changes in light interaction rather than through color or density changes. This resolves the contradiction by making the mark detectable while maintaining content readability.
2Difficulty of detecting and measuring
If a colored toner layer is applied beneath the content layer to create a visible mark, then the mark becomes easily identifiable, but the mark creates a washed out appearance and reduces content readability
Solution Approach 1:
The patent uses clear toner that changes optical properties through light reflection rather than applying color. The clear toner particles reflect light differently than the substrate, creating a visible mark without adding color that would interfere with content. This allows the mark to be easily identifiable while maintaining content readability.
Solution Approach 2:
The clear toner acts as an intermediary between the substrate and the viewer's eye. Instead of directly applying colored toner that would interfere with content, the clear toner mediates the light interaction, creating a visible mark through optical property changes while allowing light to pass through to the underlying content, thus maintaining readability.
3Object-generated harmful factors
If a fluorescent watermark is used that requires visual aids to be viewable, then the mark is not viewable under casual inspection, but the mark can be made viewable when illuminant alters light conditions
Solution Approach 1:
The patent uses clear toner that creates optical property changes through light reflection, allowing the mark to be detectable under casual inspection without requiring special illuminants or visual aids. This differs from fluorescent watermarks that require altered light conditions by using inherent optical property differences between the clear toner particles and the substrate.
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
The system enables the creation of a transparent mark that is easily identifiable and does not interfere with the content, providing a noticeable glossy appearance that is observable without altering the viewing conditions, thus addressing the challenge of mark visibility and content readability.
Implementation Method 1
The clear mark is formed of clear toner particles that reflect light differently than the substrate
Data Source
AI summary
A method for forming a variable data job includes a fixed original image provided by original image data in a first multiple channel color plane and content provided by variable image data in a second multiple channel color plane. The original image data is converted to fixed image data in a clear channel color plane. Raster image processing is performed on the fixed image data to translate the fixed image data into a first ready-to-print file. The ready-to-print file is saved in a memory as a post-RIP file. The variable image data is subsequently provided in at least the second multiple channel color plane. Image processing is performed on the variable image data to obtain a second ready-to-print file. The post-RIP file is merged with the second ready-to-print file for forming the variable data job. The variable data job is printed to render output.
