Yazar: Mert KILIÇ (Print Quality Engineer) - June 2, 2026

Learn how print head resolution (DPI) impacts barcode scannability, small text crispness, and logo graphics quality.

Printhead resolution (DPI - Dots Per Inch) dictates minimum line clarity and small text sharpness. ### Resolution Guidelines - **203 DPI**: Cost-effective for standard 4x6 shipping labels and large box barcodes. - **300 DPI**: Industrial standard for product labels, medical (UDI) labels, small 2D barcodes, and 6-8 pt text. - **600 DPI**: Ultra-high precision for PCB micro-labels, jewelry tags, and vial stickers.
