Please check in the design editor and in the shopping basket if the backside is blank or if there is a pattern. If there is a pattern, it cannot be removed. If there is a full-page image frame that you do not fill with a photo, the background will print - as visible in the shopping basket preview. If you choose glossy coating (on our silk cardstock), this is applied only to the front side in the case of flat cards, and the front+back in the case of folded cards.
