+**Pro Tip™**:
+For the best results, use image files with the matching pixel dimensions. Die-cut labels have to be in the exact pixel dimensions stated above. For endless label rolls, you can provide image files with a pixel width as stated above. If you provide a file with different dimensions when creating an endless label file, it will be scaled to fit the width.
