## Summary description

KOH-I-NOOR Diamant A4 technical drawing paper, 90 g/m², pack of 10 sheets. High-opacity, smooth-surfaced A4-format paper designed for precise pencil, ink and technical drafting work.

## Long description

KOH-I-NOOR Diamant A4 technical drawing sheet, 90 g/m², pack of 10 sheets provides a medium-weight, smooth-surfaced paper designed for precise pencil, ink and technical drafting work. The A4 format and consistent sheet quality make it suitable for school projects, architectural sketches, engineering drawings, tracing and general-purpose office use where stable, non-transparent paper is required. Each sheet offers reliable surface resistance for accurate line work and good erasure tolerance for iterative drafting.
Advantages
The 90 g/m² weight balances rigidity and ease of handling, reducing buckling during inking and allowing clean pencil definition. A smooth, even surface improves line clarity for technical pens and pencils, while higher opacity minimizes show-through when placed over other documents or tracing templates. Packaged as 10 sheets, the product is convenient for small projects and regular classroom or office needs without excess waste.
Suitable for
 Technical drawing and drafting with pencils and technical pens
 Architectural and engineering sketches and plans
 School and university projects, exercises and assignments
 Tracing and overlays for design work
 General-purpose office documents requiring stable, medium-weight paper
Key specifications
 Format: A4 (210 × 297 mm)
 Weight: 90 g/m²
 Surface: smooth, suitable for pencil and ink
 Opacity: high, reduced show-through
 Pack size: 10 sheets
How to use
Place the A4 sheet on a clean, flat drawing board or desk. Use sharpened pencils or appropriate technical pens for fine line work and apply consistent pressure to maintain uniform strokes. For tracing, position the sheet over the original and secure with low-tack tape to prevent movement. When inking, allow pencil guidelines to dry or erase lightly after ink sets to avoid smudging. Store unused sheets flat in a dry environment to preserve surface quality.
Usage recommendations
For best results, combine with soft to medium hardness graphite pencils (HB–2B) for sketching and fine liners with 0.1–0.5 mm tips for inked details. Avoid heavy washes or saturated media; this paper is optimized for dry and light wet media typical in technical drafting.
