Overview
Template 4 provides the best machine readability and human readability in a single label for those with smaller amounts of data (10 numerals or 6 alpha characters, maximum).
Specs
Maximum data: 10 numerals or 6 alpha characters (The maximum alphanumeric length depends on the character mix.)
Design features
• Code 128 is very common and offers good data density for this size label.
• Narrow bar width gives good readability and accommodates a good amount of data.
• The blank margin to the right of the barcode will fluctuate in size with the amount of data encoded. The example shows the maximum length barcode while still maintaining a 3.81-mm (0.15-in) right margin.
• The barcode extends from top to bottom to maximize vertical redundancy, which facilitates machine readability.
• Minimal space separates the barcode and the text.
• The blank margin separating the text field and the barcode is 0.64‑mm (0.025-in) wider than the minimum quiet zone required for machine readability.
• The Droid Mono Bold font offers consistent character spacing, discernible characters, and a modern look.
• The text height is maximized within the height of the label.
• A blank margin above the text allows for 0.76‑mm (0.030‑in) vertical print drift.
• A blank margin below the text allows room for lowercase descenders, such as g and q, while also providing allowance for vertical print drift.
• The left margin allows for horizontal print drift.
• The horizontal scaling of the text field squeezes enough characters onto the label to match the maximum data encoded in the barcode.
