Process Introduction
Colored back strips start with dyed long‑fiber kraft paper (color added during pulping). The dyed paper then undergoes the standard coating, drying, and slitting process. No surface printing is required – the color is uniform throughout. For custom Pantone colors, small batch runs are available. The adhesive is clear or tinted to match, ensuring a clean finish.
