Delamination occurs when there is a detachment of the top layer or coating layer of carton board and can be seen after the printing step in the form of bubbles on the carton board surface or a large scale detachment of the carton board cover layer – when this happens, the product is downgraded to waste.
The Seeker is looking for strongly effective methods to eliminate the risk of delamination of the cartonboard during printing processes.
This is a Reduction-to-Practice Challenge that requires submission of written documentation. The Seeker will perform experimental validation of proposed solutions in order to determine the award.
Due to high printing speeds and accordingly high dynamic forces created in the board and/or in printing dye during the printing process, the board tends to locally delaminate. When this happens, the product is downgraded to waste.
The Seeker is looking for strongly effective methods to eliminate the risk of delamination of the carton board during printing processes. There are many parameters known to have a strong influence on delamination, such as temperature, ink tack, internal bonding strength of the board etc, that are discussed in more detail in the Challenge Description. Hence, the field of investigation by the Solvers shall not be limited to a particular area, as the Seeker is interested in receiving solutions from a broad range of potential approaches to a solution.
Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on April 17, 2017. Late submissions will not be considered.

What is an RTP Challenge?
An InnoCentive RTP (Reduction to Practice) Challenge is a prototype that proves an idea, and is similar to an InnoCentive Theoretical Challenge in its high level of detail. However, an RTP requires the Solver to submit a validated solution, either in the form of original data or a physical sample. Also the Seeker is allowed to test the proposed solution.
