When designing stickers, it's important to consider how they will appear once they've been printed. If you're considering using line borders around the edge of your design, there are some important factors to keep in mind.
One potential issue is that during the printing process, there is typically a margin of error of around 2mm for movement. This means that even if your design is perfectly centered when you submit it, there is a chance that it may shift slightly during printing. If this happens, the border may appear closer to one edge than the others, which can create an asymmetrical look that detracts from the overall appearance of the sticker.
To avoid this problem, we recommend avoiding line borders around the perimeter of your design whenever possible. Instead, consider incorporating other design elements, such as color gradients or patterns, to create a visually appealing sticker without relying on a border. If you do choose to use a border, make sure to carefully review your design and account for the potential for movement during printing.
