Narrow web.

Roll-fed printing and converting of labels and flexible packaging, distinct from both wide-format and garment printing. The width that separates it from wide web is quoted confidently and differently by everyone who quotes it: a flexo press maker puts the ceiling at under 20 inches (508 mm) and calls its own figure "an arbitrary designation", a trade glossary says under 400 mm, and another press maker says 16 inches or less. Treat any single number for it as that source's convention rather than a definition, and ask which one a spec sheet is using before comparing two presses on it. This entry previously said 330 mm (13 in): that is real trade vocabulary, but it names a once-common press width inside the category rather than the boundary of the category, and repeating it as the definition gave the term a precision the trade does not have. What the label holds steady is the shape of the work, and that is what matters to a decorator reading a vendor claim: inspection and colour systems built for this world, AVT and BST among them, watch a continuous web running at web speed on film or paper. None of it carries over to a garment line moving discrete pieces, however similar the inspection claim reads.
