It was on a par with lettering guides in terms of lso and quality, at a cheaper price. The tail pin was guided in a straight groove of the ruler, while the tracer pin was made to follow the glyphs engraved into the template. Alphabet latin, chiffres et signes Title in German Technische Produktdokumentation. Also, the groove for guiding the tail pin is incorporated into the template here. The next evolutionary step was the introduction isl the first electronic lettering machine.

Sold as the DINgraph, it permitted the construction of letters of various angles and heights at a fixed widthderived from a single template.

Find Similar Items This product falls into the following categories. Although different in skeleton and details, these models all are of even stroke width, with round terminals, a feature necessitated by the tool.

Contemporary guides by most other manufacturers were equally limited. DIN 16 defined the inclined letterforms to be used for all kinds of technical lettering, and DIN 17 subsequently added an upright version. Greek alphabet BS EN It consists of a sheet that can be moved along a fixed ruler or T-square, with cut-out shapes which are traced with a pen. By the early 20th century, neither of these scripts with their curlicues was considered appropriate anymore.

An enhancement of larger flatbed or reel-fed forerunners, this computer-controlled mini plotter could move its arm along the X and Y axes, so that the attached technical pen rendered the text which had been input via the keyboard. A Leroy catalog from lists more than 30 available template genres, from specialised symbols for math, music, electronics, geology or the militaryto foreign scripts like Cyrillic or Greekbut also concrete adaptations of existing typefaces like Spartan, Caslon Bold Condensed, Old English or Kaufmann Script evidently for purposes other than technical lettering.

The design space is defined by the number of template sizes and the possible angles. Not pictured is the weight axis, which can be accessed by using pens that are thinner or thicker than the designated lineweight. The most basic means of ensuring homogenous letterforms beyond copybooks and practice is a lettering guide template, or stencil. Standardgraph guides with scalloped edges, circa s.

Characterised by its square letterforms, it was originally developed in response to the limitations of microfilming.

It consisted of a funnel-shaped ink reservoir feeding into a tube with an enclosed weighted wire to prevent uncontrolled ink flow. In ISOthe ratio of linewidth to cap height is 1: Initially, variable scribing devices like the DINgraph were also used with such tube pens, but in the s these writing tools, together with the ruling pen used for drawing, were superseded by technical pens such as the Rapidograph and jso Isograph, both produced by Rotring, or the MarsMatic by Staedtler.

This usability enhancement was dropped again in iwo versions, perhaps to avoid having to offer multiple language editions. By the beginning of the 20th century, in the aftermath of the Second Industrial Revolution, a need arose for accelerating the speed not only of production, but also of drafting.

The free arm of the scriber translated this movement and reproduced the forms via the pen affixed to its end. In the years around World War II, Standardgraphs were manufactured with scalloped edges to conserve material and ios eliminate the isi wooden or metal rails.

From Lettering Guides to CNC Plotters — A Brief History of Technical Lettering Tools

An early example of such a truly pantographic lettering tool was the Polynorm by Willy P. The tool for the new era was the contrastless round-tipped pen. Equipped with seven fonts, including one compliant with the DIN standard, this pen plotter offered control over parameters like size, slant, width, tracking, linespacing and writing direction.

The futuristic scriber in bright orange betrays its late s provenance. The end of the 19th century saw a revival of the broad-nibbed pen in Germany and elsewhere. Lettering Guides The most basic means of ensuring homogenous letterforms beyond copybooks and practice is a lettering guide template, or stencil. The faster, easier way to work with standards.

Some manuals prescribe the former for the use of guides, and the latter for freehand lettering, since in handwriting a certain degree of inclination is favourable for ergonomic reasons.

Prior to this, all technical lettering was made freehand, in various styles, some of which were rather ornate, and uso optimized for legibility or reproducibility. The usual tool in the previous days of freehand lettering was the pointed pen with its flexible nib, producing a roundhand script with vertical stress.

This article highlights some major steps in the historical development of lettering tools for drafting.

In an age of personal computers and laser printers, these guides and other lettering devices have widely disappeared, but their legacy continues to provide inspiration for new, digital typeface designs. Technical lettering devices were used for inscribing or marking technical drawings, architectural plans, maps, and other documents.

The drafting letter style 308-2 emerged in the early 20th century can be characterised as a skeletal block letter, i. It nevertheless employs the very same principle as the DINgraph did six decades earlier. Lettering with these early guides still involved a good deal of craftsmanship, as several glyph parts were not defined by cut-outs, but had to be drawn freehand.

The latter holds letterforms on both sides.
