When I redesigned the deck for a poker size card, I had to fiddle with the images and chose to add a white rim around the image to fill in the "bleed" area... Bad mistake! I simply should've extended the background colours beyond the printing limits. That way, it would ensure that however lined up the cards were in the cutting machine, there would be colour all the way through to the edge. Most of the cards are perfect, though; there are only a few that have a white edge. This is, of course, more apparent on cards that have a darker background. As this is only a deck for my personal use, I don't really care about the white edges, but if I go ahead and publish it, I will most definitely take the time to re-design them in a manner that avoids this white-edge effect. It was a good learning lesson for me as this will ensure than any of my future card projects won't suffer this same mistake.
