For smart labels, a premium viewer visualizes the RFID inlay placement. It allows you to toggle between "Visual Label" and "RF Field Map" to ensure the antenna is positioned over the printer’s encoder module.
High-volume labeling often involves serialized barcodes, batch numbers, or expiration dates. A basic viewer shows a static template. A high-quality viewer lets you inject sample data to see how the final label will look with real values. This prevents "variable field overflow" errors where a 20-character serial number truncates inside a 10-character box.
The viewer must ship with a validated set of Intermec resident fonts. It should also accurately render scalable fonts like Swiss 721 (Helvetica equivalent) and Dutch 801 (Times equivalent) at various pitch sizes (10, 12, 17 cpi).
