Both technologies print with heat, but they age differently, cost differently and suit different jobs inside eyewear and optical stores.
The thread running through this guide is precision slitting and narrow edge tolerance, tight web-width and edge-camber control so the ribbon-like web tracks perfectly. When it is specified and converted correctly, operations gain a web that tracks straight, shift after shift, a quiet advantage that compounds across thousands of labels. Xinwei's role as factory-direct producer, not reseller, is what makes that consistency achievable in eyewear and optical stores.
Q: What MOQ and lead time are realistic for custom labels?
Standard formats support small MOQs because tooling already exists; fully custom constructions need larger but usually modest runs once setup is amortized. Lead time follows slitting, die-cutting, optional pre-print, QC and packing. A factory quotes against its own real schedule.
Q: Which label size should I choose?
Start from the encoded data, reserve barcode quiet zones, add text lines, then check the shape against the product and the limits of the printer. Standards such as 4x6 inch (100x150mm), 60x40mm and 50x30mm cover most needs; a real factory cuts custom dies quickly when standard sizes do not fit.
Q: Why are batch codes on the carton important?
Batch codes trace rolls to coating run, converting shift and packing, which makes complaints diagnosable, supports rotation by freshness and underpins compliance traceability. Untraceable trader stock offers none of this when a problem appears.
Q: How do I plan labels for peak season?
Lock the construction and golden samples early, reserve factory capacity with a rolling forecast, buffer the few critical SKUs from burn rate and real lead time, and service printers before the rush. During peak, nothing should change except volume.
Q: What is linerless thermal labeling?
Linerless webs carry a release coating over the face and a patterned adhesive, with no liner to throw away; the printer cuts variable lengths on demand. It reduces waste and suits variable-length workflows, though it needs compatible printers. Conventional optimized liners are the lighter-touch alternative.
