The label shown in the figure is a silver polyester label with 3 face slits. The slits divide the one larger label on the liner into 4 very thin labels that you peel and place onto the item you want to mark. Run the roll of labels through your printer to print the bar code onto the slitted label and you wind up with four very skinny bar coded labels.
Now you have a way to bar code very small components or parts. Using a slitted labeling technique is a convenient way to print multiple labels for various applications. Do you have any interesting tips on better ways to label? Let us know!
