Difference Between DPM Barcode Scanner and Traditional ones

In barcode scanning technology, DPM barcode scanners and traditional barcode scanners each have their own unique advantages and applicable scenarios. A DPM barcode scanner is a device specifically designed for reading barcodes that are directly printed or engraved on the surface of objects. Compared to traditional barcode scanners, DPM barcode scanners have higher precision and adaptability, allowing them to handle more challenging barcodes. Understanding the differences between the two is crucial when choosing a scanner that meets your needs.

Different Scanning Targets

Traditional barcode scanners are mainly used for reading barcodes attached to labels, such as paper or plastic labels. They are very suitable for scanning smooth, clearly printed barcodes that are typically attached to product packaging, labels, or cards.

In contrast, DPM barcode scanners can read barcodes that are directly printed or etched on the surface of objects. These barcodes often appear on metal, plastic, or other irregular surfaces. DPM barcode scanners can handle barcodes printed using Direct Part Mark (DPM) technology, which may be present on surfaces that are irregular, worn, or coated, and still efficiently read them. For barcodes that need to be marked on irregular or hard surfaces (such as electronic components, automotive parts, metal tools, etc.), DPM barcode scanners are undoubtedly the ideal choice.

Scanning Accuracy and Clarity

Traditional barcode scanners usually require the barcode surface to be flat and the barcode printing quality to be high to ensure scanning clarity. If the barcode is damaged, stained, or unclear, the decoding ability of traditional barcode scanners will be affected, leading to scanning failure or inefficiency.

DPM barcode scanners, on the other hand, use more advanced image processing technology, and can maintain a high recognition rate even when the barcode surface is somewhat irregular, stained, or worn. Because DPM technology uses directly printed barcodes, it often can cope with complex surfaces and very small barcodes, greatly improving scanning accuracy. This precise decoding ability is especially important in industrial manufacturing and precision equipment fields.

Ability to Adapt to Complex Environments

Traditional barcode scanners are mostly used for scanning barcodes in fixed positions, suitable for relatively simple application scenarios, such as retail and warehousing.

DPM barcode scanners have a significant advantage in this aspect. They usually have stronger adaptability, capable of operating normally in complex environments such as high temperature, high humidity, and oily conditions. Whether on metal surfaces or other rough surfaces, DPM barcode scanners can efficiently recognize barcodes, ensuring data transmission is not disrupted.

Scanning Distance and Speed

Traditional barcode scanners typically have a shorter scanning distance, requiring the barcode to be placed within the scanning range of the scanner, and usually rely on the proximity of the device for reading. This method is sufficient for most common barcode applications.

However, DPM barcode scanners can generally scan at a greater distance and quickly read barcodes that are printed smaller or located in more remote positions. This characteristic makes DPM barcode scanners more suitable for large-scale industrial production or automated assembly lines. By optimizing focusing and scanning technology, DPM barcode scanners can quickly identify barcodes on complex surfaces, greatly improving work efficiency.

In summary, DPM barcode scanners and traditional barcode scanners have significant differences in many aspects. DPM barcode scanners can handle more complex and irregular barcodes, are particularly suitable for use in harsh environments, and have stronger adaptability and decoding capabilities. Traditional barcode scanners, on the other hand, are more suitable for use on smooth surfaces and relatively regular barcode applications. If your work environment requires handling barcodes directly printed on the surface of objects, DPM barcode scanners are undoubtedly a better choice.
