Process Introduction

90g paper uses the same acid‑free high‑viscosity beating (≥90°SR) but with optimized fiber blend (75% softwood, 25% hardwood). The stock is formed at 0.6‑1.0% consistency, then pressed and dried at low temperature. Semi‑dry calendering at 100 kN/m linear pressure compacts the sheet. Surface sizing with formaldehyde‑free biological glue ensures water resistance. Final moisture balanced at 6‑8% to prevent curl.

Applications & Advantages by Category
  • Engineering Drawing Reproduction – The go‑to weight for manual tracing and master drawing creation.
  • Diazo Blueprint Making – Ideal base paper for ammonia‑based blueprint machines; light‑fast and stable.
  • Architectural Archiving – Long‑term storage without yellowing or brittleness.
  • CAD Plotting – Compatible with wide‑format inkjet plotters; high tear resistance.
Why Choose This Paper

90g is the industry benchmark – proven reliability for professional engineering and architectural workflows.
