Carbonless paper (also called NCR — No Carbon Required) uses micro-encapsulated dye on the back of the top sheet (CB) and a reactive clay coating on the front of the bottom sheet (CF). When pressure is applied, the capsules burst and the dye transfers, creating an image. Carbon paper is a separate sheet coated with carbon ink that sits between two regular sheets. Carbonless is cleaner, more efficient, and the industry standard for multi-part forms.

Absolutely. Kingcolor offers custom cut sheet sizes from 3″×5″ up to 25″×38″ with a tolerance of ±0.5 mm (or ±0.2 mm for precision jobs). We can also add perforations, punching, and corner rounding. Just send us your press specifications, and we'll recommend the optimal sheet dimension and packaging format.

For standard sizes and colors (white/canary/pink), production takes 7–10 days after confirmation. For custom sizes, colors, or special coatings, allow 12–15 days. Ocean shipping to the US West Coast takes approximately 12–15 days, and door-to-door DDP usually completes within 25–30 days total. Express air freight can reduce this to 7–10 days.

Store in its original sealed packaging, away from direct sunlight, heat sources, and extreme humidity. We recommend a "first-in, first-out" inventory system.
