Technical Drawing Block SCHEMAT A4, 10 Sheets, 170 g/m², White, Pack of 20

SCHEMAT Technical Drawing Block A4 is a pad of high-opacity white sheets designed for precision sketching, tracing and presentation of technical drawings. Each pad contains 10 sheets of 170 g/m² paper that provide a sturdy, smooth surface suitable for pencil, technical pens, ink and markers. The product is supplied as a pack of 20 pads, offering a reliable volume for studios, classrooms and professional workflows that require consistent paper quality in A4 format.

Advantages

The 170 g/m² paper weight ensures minimal show-through and a robust feel that resists buckling with wet media. The white, uniform surface supports accurate line reproduction and clean erasing without excessive abrasion to the sheet. A4 format and 10-sheet pads offer convenient portability and staged use, while the pack of 20 provides cost-effective replenishment for repeated projects or group settings.

How to use

Use individual sheets directly from the pad for sketching, tracing or final line work. For tracing, place the pad sheet over the source drawing and use a light table or steady backlight if available to improve visibility. When using markers or wet ink, allow sufficient drying time before stacking to prevent offsetting; heavier strokes may benefit from supporting the sheet on a rigid surface. Sheets can be removed cleanly from the pad edge for presentation or archival storage.

Usage recommendations

Store pads flat in a dry environment to maintain paper flatness and prevent moisture absorption. For archival or long-term presentation, mount final drawings on a supportive backing. Test any solvent-based markers on a spare sheet first to confirm no bleed-through or unwanted feathering occurs.
