Light-Sensitive Coating for Duplicate Check Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing duplicate negotiable instruments, such as checks, are time-consuming and costly due to the need for personalized information on both the original and duplicate versions, requiring multiple printing steps and increasing production time and costs.
Innovation Solution
A printing system that uses a light-sensitive coating on duplicate base stock to transfer information from an original negotiable instrument to its duplicate, reducing the need for printing personalized information on both by using a mated base stock exposed to light, such as UV or laser light, to achieve a legible and human-readable transfer of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personalized information is printed on both original and duplicate negotiable instruments, then complete transaction records are achieved, but production time and costs increase
Solution Approach 1:
The patent applies the copying principle by transferring printed information from the original negotiable instrument to the duplicate through light exposure. The duplicate base stock contains a light-sensitive coating that captures the printed information optically, creating a legible copy without requiring separate printing operations. This reduces production steps while maintaining complete transaction records on both original and duplicate instruments.
Solution Approach 2:
The patent uses light as an intermediary medium to transfer information from the original to the duplicate negotiable instrument. The light-sensitive coating on the duplicate base stock acts as a mediator that receives light exposure through the original's printed areas, thereby transferring the information without direct physical contact or complex printing mechanisms.
2Manufacturing precision
If multiple printing steps are used for personalized information, then accurate personalization is achieved, but production costs increase
Solution Approach 1:
The copying principle eliminates multiple printing steps by using optical transfer. The light-sensitive coating on the duplicate base stock directly captures the printed information from the original through light exposure, achieving accurate personalization in a single step rather than requiring separate printing operations for each duplicate.
Solution Approach 2:
The patent replaces mechanical printing systems with an optical system. Instead of using printing presses and ink application mechanisms for each duplicate, the invention uses light exposure and photochemical reactions to transfer information, significantly simplifying the device complexity while maintaining personalization accuracy.
3Productivity
If light-sensitive coating is applied to duplicate base stock, then information transfer is achieved, but additional coating process is required
Solution Approach 1:
The light-sensitive coating is applied to the duplicate base stock in advance, before the actual information transfer process. This preliminary action allows the duplicate to be ready for rapid information transfer through light exposure, improving production speed while the coating application itself remains a standard manufacturing process that can be integrated into existing production lines.
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 method allows for the production of duplicate negotiable instruments with reduced printing requirements, cutting production time and costs in half while maintaining legible and accurate transfer of information, enabling efficient and cost-effective production of personalized checks.
Implementation Method 1
a light-sensitive coating applied to a portion of a base stock of a duplicate negotiable instrument... The mated base stock is exposed to a light (e.g., laser light, UV light, or a visible light source) and information on the base stock of the negotiable instrument is transferred to the coated areas of the base stock of the duplicate negotiable instrument
Data Source
AI summary
A system in which a check and its duplicate are formed. In an embodiment, a mating device mates a base stock of a negotiable instrument with a base stock of a duplicate negotiable instrument to form mated base stock. In one embodiment, the base stock of the duplicate negotiable instrument has a photosensitive coating applied to a portion of the duplicate negotiable instrument. A printing device may be used to print personalized information on the base stock of negotiable instrument portion of the mated base stock. Also, an exposure unit may be used to apply light to the mated base stock, wherein the application of the light to the mated base stock transfers a portion of the personalized information on the negotiable instrument to the duplicate negotiable instrument.
