Removable Varnish Marking System for Game Cards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking systems for game cards, such as instant lottery tickets, are limited in their ability to provide clear and sharp visibility of indicia, offer limited color and design options, and lack effective security measures, making them difficult and expensive to implement.
Innovation Solution
A marking system that applies a removable varnish or rubber-based layer with an overlying screen of opaque ink elements, allowing for blended tones and varying densities to enhance visibility and security, while enabling players to mark indicia by scratching off the removable layer, thereby providing clearer and sharper image clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a removable translucent layer is used to mark indicia, then the marking function is achieved, but the clarity and sharpness of the underlying indicia are limited
Solution Approach 1:
The patent divides the marking system into multiple functional layers: a base layer with indicia, a removable translucent layer for marking, and an overlying screen layer with opaque ink elements. This segmentation allows each layer to perform its specific function optimally while maintaining overall system performance.
Solution Approach 2:
The patent adds a third dimensional layer (the overlying screen) on top of the traditional two-layer system. This additional dimension provides enhanced visual effects and security features without compromising the clarity of the underlying indicia when the translucent layer is removed.
2Adaptability or versatility
If multiple transparent layers are used for marking, then more color options are available, but the implementation becomes more difficult and expensive
Solution Approach 1:
The patent combines a translucent material layer with an overlying screen containing opaque ink elements to create a composite marking system. This composite structure provides diverse color and design options while maintaining manufacturing feasibility through a structured multi-layer approach.
Solution Approach 2:
The overlying screen applies opaque ink elements selectively in specific patterns and locations, allowing different colors and designs in different areas without requiring entirely different materials or complex manufacturing processes for each variation.
3Device complexity
If a single translucent layer is used, then the marking system is simple, but security measures and design appeal are limited
Solution Approach 1:
The patent enhances security by incorporating an overlying screen with opaque ink elements that can contain security marks difficult to reproduce, while maintaining the simplicity of the removable translucent marking layer underneath.
Solution Approach 2:
The patent nests the overlying screen layer within the overall marking system structure, containing security features and design elements within the translucent layer system. This nesting allows security measures to be integrated without adding external complexity to the basic marking function.

AI summary
A game card incorporates a marking system having one or more layers of varnish or rubber-based material that is removable when applied to a substrate and one or more overlying screens having a pattern of opaque ink elements printed on the removable layer or layers such that the ink elements are blended into smooth tones when viewed by the human eye. An optional underlying screen provides another pattern of opaque ink elements underneath the removable layer. The marking system and method of the present invention permit a wide range of combinations of designs and security measures, while ensuring that indicia printed on the game card are visible so that players can scratch or otherwise remove the removable layer and at least a portion of the overlying screen as a way of marking the underlying indicia. Whether the underlying screen is employed or not, once the removable layer is removed, the underlying indicia on the game card is surrounded by a background that is visibly distinct from the color viewed when the removable layer is in place and has not been removed.
