Sigel 12378 A3 Printer Paper

Sigel 12378 printing paper is a high-volume A3-format paper (297 x 420 mm) developed for use with both laser and inkjet printers. The pack contains 2000 sheets of 70 g/m² ECF-bleached white paper, offering consistent surface quality and bright whiteness to support sharp text and clear graphics across business documents, reports, and large-format office prints.

Advantages

This A3 paper combines compatibility with laser and inkjet technologies and a lightweight 70 g/m² grammage that reduces shipping and handling costs while remaining stable in multi-page runs. The ECF bleaching process produces a bright white tone that improves contrast and colour reproduction for printed text and charts. With 2000 sheets per pack, the product suits high-volume workflows and reduces the frequency of reordering.

How to use

Check printer specifications for supported paper sizes and the maximum recommended weight before loading A3 sheets. Load the paper stack into the printer tray or bypass feed with the print side facing according to your printer’s instructions.

When printing large jobs, monitor for curling or misfeeds and reload paper as necessary to maintain consistent output.

Recommendations

Store unopened packs in a cool, dry place away from direct sunlight and humidity to preserve paper flatness and feed reliability. For important colour-critical outputs, test a sample before mass printing and consider using a higher-weight or coated paper if enhanced colour saturation or durability is required.
