Koh-I-Noor technical pens have been used by generations of artists for precise line work. Manual designers depended on the clean lines and easy to fill pens before computer generated graphics became the mainstay of engineering and architectural work. Today, our pens are still sought after by both artists and designers who aim to bring the life and immediacy that makes hand drawn work so remarkable. Our precision technical pen work scans easily, and offers a clean rendering to be incorporated into digital work such as hand lettering, comics, and more.
Rapidograph® pens are a superior grade technical pen that offers precise, uninterrupted line work for a number of applications. These pens work best on a smooth surface as textured surfaces may cause the finer nib sizes to skip.
POINTS/NIBS: Each Rapidograph® pen features a stainless steel nib in one of 10 sizes from the hairline 6×0 (.13mm) nib to the large 4 (1.20 mm) nib. Replacement points are available for all pen sizes. Alternative tungsten carbide nibs are twice as strong as steel and are available in sizes 3×0, 00, 0. The pen also features a white plastic barrel with a refillable ink reservoir (pens do not come filled with ink), and a color-coded cap for nib selection. The double-seal cap is air-tight to keep the nib from drying out. Each pen is identified by a standard nib size or by its line width expressed in millimeters. Note: “nib” and “point” are terms used interchangeably but point sizes do not correspond to points in the point/pica system of typographic measure. A chart is available for the nib size, inch, and millimeter equivalent for each pen size in the pen care PDF.
INKS: Koh-I-Noor Inks are designed for use in our technical pens. If an alternative ink is used, it may clog or damage the pen depending on the ink’s formulation. Koh-I-Noor Inks can be cleaned with the Rapido-Eze pen cleaner. We also service Koh-I-Noor Rapidograph Pens, instructions are in the pen care PDF.
