Our carbonless offset base paper machine features a high-precision headbox with a hydrofoil design and advanced turbulence control that delivers a perfectly uniform pulp slurry across the entire width of the wire. This eliminates streak formation and fiber flocking, creating an even sheet formation that ensures consistent coating uptake later in production. We paired this with a controlled-vacuum Fourdrinier forming section and optimized dewatering that preserves fiber uniformity without over-compressing the sheet, resulting in consistent porosity that lets microencapsulated reactive coatings bond evenly to the surface. Unlike generic machines that cause uneven moisture distribution, our multi-stage infrared + cylinder drying section precisely controls moisture content through every stage of production, eliminating internal stress that causes curling after coating—one of the most common complaints from carbonless paper converters.
