UNDERSTANDING NCR PAPER: A GUIDE1. Reverse Side Printing:%u2022 Suitable for printing on the reverse side, commonly used for terms and conditions.%u2022 Offset printing is recommended for minimal pressure application.%u2022 Use light-coloured inks to prevent show-through; avoid glossy inks to maintain copying quality.2. Tinting:%u2022 Can be tinted using both alcohol- and aqueous-based inks.%u2022 Light coverage is recommended to avoid impacting copy quality, though copy intensity can%u2019t be guaranteed.3. Perforation:%u2022 Compatible with both longitudinal and transverse perforation.%u2022 CF coating%u2019s low abrasiveness extends the life of perforating tools.4. Cutting:%u2022 For guillotine cutters, maintain low press-bar pressure to prevent stack slippage and discolouration.%u2022 Use expanded rubber to minimize slippage.%u2022 Distribute stacks evenly, ideal stack height is 8-12 cm.%u2022 Remove protection sheets before cutting.%u2022 Blade angle should be between 19%u00b0 and 21%u00b0.5. Copy Lifespan:%u2022 Official tests show that NCR paper retains copy quality for over 25 years under typical storage.%u2022 Copy properties remain stable for up to three years for best results, use forms within five years.6. Storage Recommendations:%u2022 Store forms away from chemicals, vapours, fumes, and bright light.%u2022 Avoid using plasticisers in plastic films and sheets as they can impair copying.%u2022 Polyethylene products are recommended for storage to ensure longevity.PenTop SheetMicrocapsules of InkMiddle SheetReactive Clay LayerBottom SheetWhat is NCR Paper?%u2022 NCR: Stands for No Carbon Required.%u2022 Types: CB (Coated Back), CFB (Coated Front and Back), CF (Coated Front).%u2022 Composition: These are specialised sheets or reels coated with micro-encapsulated ink, dye, or reactive clay to facilitate pressure-sensitive copying.Key Points to Remember%u2022 NCR paper is activated by pressure and relies on precise chemical properties.%u2022 Using incorrect chemistry or applying excessive pressure can damage the capsules, leading to poor image transfer or bruising.%u2022 Mixing different brands of carbonless paper can result in suboptimal copying due to unique technological differences among brands.How NCR Paper Functions%u2022 CB Sheet (Top Sheet): Coated with micro-encapsulated dye on the backside.%u2022 CF Sheet (Bottom Sheet): Coated with reactive clay on the top surface, which reacts with the dye from the CB sheet to create a copy.%u2022 CFB Sheet (Middle Sheet): In multi-copy setups (triplicate, quadruplicate), these sheets have reactive clay on the top side and dye on the underside to enable multiple copies.Key Differences Between Resin and Clay NCRCoating Material: Resin NCR uses a resin-based coating, while Clay NCR uses clay.Durability: Resin NCR is typically more durable and suitable for demanding applications compared to Clay NCR.Print Quality: Resin NCR generally offers better image clarity and smoothness compared to Clay NCR.Resin and clay NCR papers can be used in conjunction, but any potential printing issues cannot be guaranteed by the supplier.Handling NCR Paper19
