This File Error is given by our Prepress team if you have ordered a circular product (sticker, hangtag, coaster, etc.) and your artwork includes a border.
The reason this warrants a File Error is because slight shifts in production are more common with die-cut products and you will likely see your border shifted and off-centre on a large portion of your order.
We have high standards for the quality of our finished products. Since we know this issue to commonly cause quality control issues, we will ask you to remove the border from your design if you have received this File Error message.
We cannot guarantee an even border and a reprint will not be able to be given if you request us to print a circular product with a border.
