There does appear that a few decks produced did not have this issue
@upNdown which is good for those few who received good sets.
@T_Chan maybe a short video of current opened decks but then open two or three sealed decks to show comparison.
@kk405 i would contribute what you can from the already opened decks that you have.
Here is the Kickstarter post:
Hello everyone,
So I received news from my manufacturer that they did an in depth test on the sample decks that I shipped back. It did take a bit longer than expected as they are in the middle of a big production run currently. I flagged the lighter hue and darker hue cards so that they could see clearly the issues that were present and apparent especially in the red decks, but also the blue. They had a special team to look them over, but said they could not see the anomalies presented to them.
I am disappointed to say the least in this response, so I invite you to tell your experiences (when were issues noticed, by you or another player, share images, a short video, etc.) to Modiano, who produced the cards. Use the first email on their contact page, here:
http://www.modiano.it/eng/contatti.html. Use the subject line of Issues with Bridge/Jumbo Index Cards produced for Desjgn. Be candid but polite. It is possible to express our feelings of disappointment without being mean and angry. Let’s see what their response will be. If they still feel that there is no issue, then I will have the cards reprinted and produced elsewhere at my expense.
Thank you everyone. I think if they hear from many of you that they will see that it is a pretty big concern and not just think that it is only coming from me. Include examples of the blue decks as well, even though the reds are far more apparent.
