Did you know that some manufacturing process requires bar code identification and packaging labels of up to 15 components?
You must know that if you decide to print the labels by yourself, you must select the correct barcode printer and must take in consideration some possible limitations.
Common thermal printers cannot print on labels much smaller than half of an inch. Because of the limited printing space and reading capabilities, you will be needing a high-density code. For high density bar codes, you should use a thermal printer with 300 DPI or even 600 DPI resolution for smaller labels.
In order to be sure that you will be printing your data in the correct location on every single label, you should look for a printer with tight registration. The tight registration can be defined as the measurement of the maximum image drift within a roll of media.
This is very important with micro labels, as precise printers with tight registration allow you to fit more information on each label – with no drift. Tight registration also ensures that the barcode is printed in the right location so that it can be reliably scanned. In contrast, printers with too much drift often produce labels with partial barcodes that cannot be reliably scanned.
A higher resolution printer can be of a great advantage because it enables you to optimize your label by printing smaller, denser barcodes and other data. A printer supporting 600 dpi resolution is necessary when:
- Your labels are less than 0.5” x 1”
- You need to include text or regulatory symbols at sizes smaller than six points
- You are printing fonts less than 10 point (such as Chinese symbols)
- You are printing barcodes less than 0.25” x 0.25”
A high-resolution printer enables you to print very small, readable font characters on your label. This lets you fit more data on your labels, saving you time and money.
Micro labeling applications also require specialized materials. For example, small electronic components, such as circuit board, require labels that can withstand temperature as high as 250° C or greater. Medical devices labeling must be made of materials and contain printed information that can be wiped repeatedly with harsh cleaning chemicals without smearing or fading. Products or components with rough surfaces need labels with a high-tack adhesive to ensure the label adheres properly to the surface. Many common product specifications also require specialized labels to comply with UL certifications, among others.
