Narrow Web Presses

• Narrow web presses are generally less than 24" in width.
• The original narrow web presses were used for printing self-adhesive tape with simple markings or company names and logos.
• There was no need for large equipment for this process.
• With the printing of pressure sensitive and self-adhesive labels, some for of die cutting had to be included.
• The primary distinction of narrow web presses is the ability to perform multiple converting operations along with printing on the same pass through the press.
• This provides a complete converting system for pressure sensitive labels on sheets, in roll form or fanfold stacks.
• Most converting on flexo presses is rotary rather than reciprocating.
• Narrow web presses are used for short run, quick changeover work.
• Products printed on narrow web flexo presses include Small folding cartons, Business forms, Closures (lids for juice and yogurt), Tickets, Tags, Flexible packaging, Multiple layer coupons and Pressure sensitive labels.
• The most critical variables for best performance of narrow web presses are tension control, anilox roll selection, precision impression setting, diecutting pressure and the quality of prepress.
• Tension control is essential for good register.
• Impression setting establishes print quality.
• Without these dot gain cannot be controlled, colors look muddy and quality suffers.
