Template 7—Data Matrix symbology with two small text fields Example label Label Editor parameters and preview Overview The use of the Data Matrix symbology with this dot size allows a large amount of data to be encoded into a symbol that only uses a small portion of the label. Template 7 leverages the large remaining space for two text fields. The upper text field can contain any extra information that might be useful on the label. The lower text field is sized to match the same number of characters that can fit in the barcode. Specs Maximum data: 36 numerals or 25 alpha characters (The maximum alphanumeric length depends on the character mix.) Design features • Data Matrix is a very dense and a very popular 2D symbology. • The dot size used in this template is relatively conservative for readability, but still allows for twice the amount of data that can fit on a label with the Code 128 symbology. • Generous margins are provided on both the right and left of the barcode. • The blank margin above the barcode allows for 0.89‑mm (0.035‑in) vertical print drift. • The blank margin below the barcode will vary depending on the amount of data encoded. The example shows the maximum data length while still maintaining a 0.89‑mm (0.035‑in) bottom margin. • The barcode is positioned to the left of the text in the event that too much data is used for the text fields. In this case, the text will run off the right edge of the label and will not interfere with the barcode. • The Droid Mono Bold font offers consistent character spacing, discernible characters, and a modern, attractive look. • Text field 1 (top) offers good legibility and space for up to 26 characters. • Text field 2 (bottom) compresses the horizontal scaling to match the data that can be encoded in the symbol. • The text fields are left-justified to allow for the longest possible strings in the available space. • Margins above and below the text are adequate to allow for some vertical print drift.
