Selective Image Transfer Using Dual Ink Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printing systems, particularly cold-set web presses, produce lower quality images with lower resolution compared to sheet-fed and heat-set offset presses, and there is a need for innovative methods to create novel consumer products with creative end uses.
Innovation Solution
A method and kit for selectively transferring a portion of an image from a substrate to a dough, such as Silly Putty, using a combination of transferable and non-transferable inks, where the transferable ink is printed using a sheet-fed offset press, allowing a hidden image to be revealed and transferred onto a second substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cold-set web inks are used for printing, then the printing process is simpler and dries by absorption, but the image quality and resolution are lower
Solution Approach 1:
The printing process is segmented into two distinct stages: first printing with cold-set web inks (simpler process) and then overprinting with sheet-fed offset inks (higher quality). This segmentation allows each ink type to fulfill its strengths - the cold-set layer provides base coverage while the sheet-fed layer adds fine detail and resolution without requiring the entire process to use complex high-resolution inks
Solution Approach 2:
Different regions of the printed image use different ink types strategically. Areas requiring high resolution and detail are printed with sheet-fed offset inks, while other areas use cold-set web inks. This local differentiation of quality allows the overall image to achieve high resolution where needed while maintaining the simplicity and cost benefits of cold-set printing for less critical areas
2Manufacturing precision
If sheet-fed offset presses are used, then higher resolution images are produced, but the process complexity and cost increase
Solution Approach 1:
The invention merges two different printing processes - cold-set web printing and sheet-fed offset printing - into a single integrated pressing operation. By combining the simplicity of cold-set web press handling with the high-resolution capability of sheet-fed offset inks, the system achieves high-quality output without requiring a fully complex sheet-fed offset pressing process for the entire job
3Quantity of substance
If all inks are made transferable to dough, then complete image transfer is achieved, but the ability to reveal hidden images is lost
Solution Approach 1:
The hidden image information is extracted and isolated using a specific ink composition that is selectively transferable to dough. By formulating the hidden image layer with unique ink properties (specific resin and oil content ratios), this layer can be selectively removed/transferred to the dough while leaving the main visible image on the paper, thereby revealing the hidden content without losing the overall image quantity
Solution Approach 2:
The ink composition parameters are changed to create distinct transferability characteristics. The hidden image ink is formulated with specific properties (higher mineral oil content, lower resin content) that make it selectively transferable to dough under pressing conditions, while the visible image ink maintains different parameters that prevent full transfer. This parameter differentiation enables selective transfer that reveals hidden images while controlling total ink transfer quantity
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
Enables the creation of 'secret reveal' capabilities, allowing users to uncover hidden images within visible designs, providing a unique and engaging experience by using dough to transfer and retransfer images between substrates, while utilizing different ink types to achieve selective image transfer.
Implementation Method 1
Cold-set web inks are designed to dry by absorption onto paper and by air
Implementation Method 2
pressing the dough onto an image printed on the substrate
Implementation Method 3
When the dough is lifted off the substrate and pressed onto a second substrate, the transferable ink is transferred from the dough to the second substrate

AI summary
The present invention provides kits and methods for selectively transferring a portion of an image from a substrate (e.g., paper) to a dough (e.g., Silly Putty®) comprising pressing the dough onto an image printed on the substrate. The image comprises transferable ink and non-transferable ink. At least a portion of the image comprising transferable ink transfers from the substrate to the dough and the non-transferable ink does not transfer from the substrate to the dough. The dough can be used to reveal an image that was “hidden” within the visible image printed on the substrate. The present invention also provides methods for making a substrate with an image comprising transferable ink (e.g., cold-set web ink) and non-transferable ink (e.g., sheet-fed offset ink) printed thereon, comprising using a sheet-fed offset press to print the image onto the substrate.
