Hey there, designing dudes and divas!
Our product imaging team has done some conversion analysis of our ceramic travel mug products. Right now, designs applied to the ceramic travel mugs have an oval mask applied. You can see an example of that here: http://www.cafepress.com/+,957560279
However, the oval mask creates some problems for many designs. (For an example, see this Thanksgiving mug: http://www.cafepress.com/+,882168366)
According to our analysis, most of your designs would look as good or better with the mask removed. We feel that removing the oval mask from these mugs will help them sell better, and earn you more. Our plan is to remove the masks from these designs starting Monday, November 11. We expect all the images to be updated within a week or so.
You shouldn’t need to do anything at all in response to this news (except hopefully notice an uptick in your travel mug sales). However, we wanted to give you a heads up anyway, so nobody was caught off guard or thought it was a bug.
In the unlikely event that you have a travel mug design that really, really needs to be oval, you can still remove the masked design and create an oval version of it.
