Researching Architectural Reproductions

Invented from Copies is a research project under the umbrella of Disclosing Architecture that examines an undervalued element of the archive collection: the architectural reproduction. Het Nieuwe Instituut explores how these reproduction techniques relate to the design process and to design culture.

Invented from Copies therefore speculates on possible 'new' meanings of the copy as a cultural vector. The research is introduced by an essay by Ellen Smit, in collaboration with Hetty Berens and Clara Stille-Haardt, curators of the Collection department of Het Nieuwe Instituut.

Sometimes, you suddenly develop an entirely different perspective on archival material. This happened during a symposium about the conservation and restoration of architectural archives at the Royal Library (Koninklijke Bibliotheek) in The Hague. Experts in paper preservation and restoration from around the world gathered to exchange knowledge. Architectural archives, in particular, proved to be a major headache for paper conservators. Compared to other archives, they contain widely diverse formats and materials, with varying chemical complexities, in large numbers (portfolios often have hundreds of sheets of paper), with a wide range of wear and tear.

The presentations focused on preserving transparencies, blueprints, whiteprints, diazotypes and self-adhesive plastic films (zips), and demonstrated the many varieties of photographic reproduction processes. Gradually, a world of chemical processes, photo-reproductive and other duplication techniques emerged that we as curators had never known in such detail. Indeed, we had never considered the possible cultural significance of analogue reproduction techniques in the architectural design process.

The first ‘copiers’ appeared at the end of the 19th century. Several major companies operated in this field, including the pharmacist Van der Grinten (later OCE/Canon) in Venlo and the Corns. Immig & Zoon, a company for photoreproductive prints in Rotterdam. Large wooden frames are set up in this workshop of the Van der Linden printing company in Leiden, between which a transparency with a design is placed onto light-sensitive paper and put in the sunlight to activate the copying process. The wooden frames have wheels and are tiltable to enable correct exposure to sunlight, which is very important for making a legible copy. Photo from 1901. Collection: Océ Heritage Foundation, Venlo

A blind spot

Had we missed something, we wondered? Why had we associated only hand-drawn, artistic sketches and presentation drawings with the creative design process, and excluded analogue reproductions? And what consequences did this omission have for the evaluation of architectural archives? The more we delved into this issue, the more pieces of the puzzle emerged.

For example, conventional research into architectural reproductions treats them as either a technical material issue, focusing only on technique and material, or as an art historical issue that only considers what is represented artistically and aesthetically. As such, the field of research had not discussed the possible mutual influence between reproduction techniques and the rendering of architectural designs. But what if there had been an interaction between analogue reproduction methods and design process and visualisation methods? What if architectural reproduction turned out to be a technical matter that also had a cultural purpose in the design process?

A second insight was that research into the cultural value of the architectural reproduction should be predominantly based on the collection of Het Nieuwe Instituut because, it transpired, a quiet revolution had taken place in its archives. Most of the documents in the archives of the National Collection can be traced back to the invention of photography in the early 19th century. This photographic revolution had far-reaching implications for analogue reproduction processes in architectural design practice.

A new mindset

Het Nieuwe Instituut's Disclosing Architecture_ project, which runs from 2018 to 2024, involves the extensive conservation and restoration of the architectural archives. There was the momentum to look at and evaluate the archives through a new mindset, using research into analogue reproduction techniques. In 2019, we started Invented from Copies_, a long-term study that, for the first time in the research tradition of Het Nieuwe Instituut and its previous incarnations, investigates the cultural value of the analogue copies and reproductions in its archives.

This research seeks a new evaluation framework that attempts to replace traditional thinking about the canon, based on artistic sketches, presentation drawings and unique authorship, through a multiform perspective with an unknown outcome. Until now, all we knew was the archives probably contained a great many reproductions. They were mainly considered as duplicates - reproductions in ten copies or more with the same design, image or text - or as reproductions that had acquired the status of originals because of drawings later applied by hand.

We decided to put the existing evaluation model aside and question reproductions in an open-minded and inquisitive way: not as technical documents in the shadow of the 'artistic' and unique (one-off) original, but using their characteristics as a starting point. Could reproductions have cultural value? Could analogue reproduction culture as a whole have been a driver of new cultural practices, and if so, can we start evaluating the existing collection differently? Can we redefine what we mean by the design process and what an architectural archive is?

The device was lightweight, easy to mount on a desktop, available with a base, light-intensity adjustable, and the lamps were readily available from stock. This machine saved the architect a time-consuming trip to a reprographics company and made copying easily accessible. This allowed architects to explore and apply photoreproductive prints as part of the design process. Collection Het Nieuwe Instituut, R. Wolf archive, WOLFt2

The current evaluation framework

Part of the research was a critical inspection of the collection policy and its foundations. Why do we think in terms of 'original' and 'copy'? What do we mean by these terms? Why does an original drawing have a positive association and a reproduction a negative one? And does the difference in evaluation between original and reproduction inform the collection policy? To find an answer, we need to look at Het Nieuwe Instituut's tradition of collecting. After all, this institute's archives have demonstrated a high regard for the artistic and visually appealing architectural drawing (referred to as an original) since the collection was originally assembled at the end of the 19th century. From a museological and art historical perspective, this evaluation system dates back to the beginning of the 17th century, when the status of the artist and architect transformed into artistic and intellectual genius. Consequently, the works they produced were considered to be high quality and unique originals.

A second development that perpetuated the status of an original was the creation of an architecture museum, with the first initiatives dating back to the early 20th century. This kind of museum, founded for and by architects, confirmed the architect's status as an artist. Indeed, following the creation of museums for artists' works, architects also longed for a museum in which their artistic design drawings could be kept and exhibited. From the outset, this architecture museum, one of the forerunners of the Netherlands Architecture Institute and thus of Het Nieuwe Instituut, wanted a study collection consisting of artistic sketches and attractive presentation material. Even today, there are architects who, when handing over their archives, retroactively sign designs or curate the handover, thereby preserving the architect's status as an artist.

The art-historical and architectural historical perspectives have also contributed to the appreciation of the original. As well as architects, historians of art and of architecture also attached great importance to artistic and attractive design material. This interest was partly motivated by practical considerations, in order to connect with the general public at exhibitions through the presentation of attractive and readable drawings. Art and architecture history's emphasis on the history of aesthetics and artistry also played an important role in establishing the status of the original. The influence of this paradigm is apparent in Het Nieuwe Instituut's approach to collecting, inherited from its predecessor, the Netherlands Architecture Institute, founded in 1988. The institute collects the architect's design process, thus entire archives. But donors and collectors alike primarily identify a creative design process with artistic sketches and attractive presentation drawings.

The current evaluation of reproductions

The evaluation model above is a guideline for the organisation, access, conservation, digitisation and display of archival material. Archives are often accessed linearly (chronologically), from preliminary to final designs, from initial sketches to the specification phase, and with a distinction between primary (hand-drawn sketches and presentation drawings) and secondary and documentary archive material (reproductions, photographs and documentation). This is logical, given that architects organise and transfer their archives using this structure.

Most archives and archival descriptions are therefore arranged chronologically, for both the donor and the archive collector, and distinguish between artistically and visually attractive drawings, referred to as originals, and the work archive, which consists of reproductions or copies. This understandable choice has far-reaching consequences for how we view the work archive. It is considered less artistic and less original, so lower in status, with less attention paid to the role of reproductions in the design process and the enormous variety of types of reproductions. Incidentally, this valuation is also facilitated by the nature of the material itself: reproductions don't have the right appearance. At first glance, reproductions are artistically unattractive and often resemble one another, making it time-consuming to study them seriously and interpret their role in the design process.

The fact that reproductions often relate to building techniques, specifications and construction drawings certainly also plays a role in this difficulty. For non-architects, reproductions are challenging to read and recognise a creative activity. This is in contrast to presentation drawings and beautiful sketch materials, to which we can relate without much knowledge or extensive study. Despite or perhaps because of this one-sided perspective, most copies in the Het Nieuwe Instituut's collection of archives are regarded as less valuable and inferior. For example, copies are more often disposed of, rarely selected for the search portal, and rarely appear in exhibitions or archive presentations.

In the architectural office, many architects already distinguish between artistic presentation material, which is given a podium, and the work archive, which has a less visible place and mainly consists of technical drawings and reproductions, and is a logical consequence of the work process. However, a hierarchical distinction between higher and lower value archival material is implied, which has implications for the acquisition and accessibility of the material in Het Nieuwe Instituut. Joop van Stigt’s former architectural company demonstrates such a division, with the work archive in the loft and the ‘artistic’ archive displayed in the office.

Research into analogue reproduction in the design process and design practice

In this first phase of the research, we focused on the following questions: who introduced these reproduction systems into the architectural design practice and design process, and when, how and why? We used four research methods:

  • An analysis, carried out in Het Nieuwe Instituut's archives, of analogue reproductions in the design process
  • An investigation into the introduction, evaluation and use of analogue reproductions in primary sources
  • Research through oral history into consumers' and designers' experiences of analogue reproduction methods.
  • Research using close reading.

A blueprint is a photographic print because it is made using light. Architectural design practice starts using the blueprint as a copying technique from around 1870. During the blueprinting process, the design to be transferred is first drawn onto a translucent medium that is then placed onto photosensitive paper prepared with potassium ferricyanide and ammonium ferric citrate. The documents are exposed to sunlight or artificial light for a set time. The exposed light-sensitive paper turns grey-green. After rinsing off the chemicals with water and drying the document, the characteristic blue colour remains with the design depicted in white lines as a negative image. H.P. Berlage, technical specification drawing, as a blueprint, for a house on Koninginneweg, Amsterdam, 1907. Collection Het Nieuwe Instituut, H.P. Berlage, BERL106.12.

Zips are industrially manufactured self-adhesive plastic sheets, patented in 1923 as a graphic medium for illustration and design. They are paper-thin and transparent, combining a self-adhesive layer and a removable backing, and are also available in bright translucent colours with pre-printed patterns, such as roof tiles and paving, as well as items such as trees and furniture. When construction production soars after WWII, the use of zips for design rendering increases because they expedite the process. Zips are still in use, as demonstrated in this collage for the Olympic stadium by Frits van Dongen. Here, its glossy surface is valued because it distinguishes it from digital visualisation methods.

Photoreproductive prints are also photographic prints because they are made using sunlight or artificial light, just like the blueprint. Architectural design practice has been using photoreproductive printing (also known as whiteprints and diazotypes) as a copying technique since around 1890. Like the blueprint, the process involves exposing light-sensitive paper, with the design in black lines on a translucent medium. This process uses different chemicals than the blueprint and results in a positive image. Therefore, the whiteprint is a clearer and more nuanced medium, suitable for adding changes with pen, pencil, or colouring. P. Cuypers, Whiteprint for the renovation and restoration of the Ridderzaal, The Hague, c. 1877. In the whiteprint’s margins are additions by Cuypers with design suggestions for the renovation and restoration. Collection Het Nieuwe Instituut, archive Bureau Cuypers, CUYPt114.5

Research into analogue reproduction in the design process

At what stage in the design process are analogue reproduction techniques used? Drawn designs, correspondence and documentation concerning the design are sources of research. We define the design process broadly, from the first sketch to the preliminary design, final design, specifications, implementation drawings, publication drawings and presentation drawings. By placing the reproductions chronologically in this chain of documents and naming the function of the reproduction in the design process, we hope to gain insights into changes in the design due to the reproduction technique, the relationship with the 'original', the relationship with other reproductions and the role of the reproduction in the design process.

From R. Wolf’s archive, this dossier for the design of a logo comprises a sequence of hand-drawn sketches on drawing paper that are then outlined and inked onto tracing paper. Wolf subsequently made a whiteprint of these, after which he continued to tweak the design in pencil. The file consists of dozens of transparencies and photoreproductive prints that have been drawn or written on and developed in tandem. Although we can no longer reconstruct their precise relationship, it is clear that the photoreproductive print plays a role here in the design process because it summarises a specific phase in the design process and is also a springboard for new ideas. This type of file is representative of many design files in the collection of Het Nieuwe Instituut. R. Wolf. Logo for the company D.B. Pfann, c. 1955. Collection Het Nieuwe Instituut, R. Wolf archive, WOLFt2

Research in primary sources

The research from the point of view of design practice consists of consulting primary written sources, such as magazines, architectural handbooks, product catalogues, plan explanations and publications published at the time and which we can assume contributed to the formation of a collective opinion. How did architects think and write about the new photographic copying possibilities at the time? From which disciplines did this knowledge originate? Why did architects embrace this reproduction technique in droves? Have reproduction methods influenced how information is designed, communicated and archived? What definitions did architects give to originals and reproductions? How did they perceive the interrelationships?

The Letraset company marketed zips in over 100 matt and glossy colours. They added colour to the work of artists, designers and architects, and they were heat resistant, making them suitable for light-based reproduction. In this way, different shades of grey could be obtained. Catalog of Letraset, circa 1975, p. 105. Collection: Ellen Smit.

Architectural handbooks from the 1970s show a progressive standardisation of architectural drawing. The Letratone company launched zips in the 1970s with several pre-printed perspective lines to compose an architectural design. This ‘instant’ insertion of architectural elements is also a characteristic of digital design practice. R.W. Gill, Manual of Rendering With Pen and Ink, London, Thames and Hudson, 1981 (first edition: 1973), p. 320–321. Collection Het Nieuwe Instituut, library collection 161298.

This commercial leaflet by Van der Grinten shows the enormous selection of blueprinting paper available around 1900, including paper for copying pencil lines or a combination of pen and pencil and a special paper more resistant to sunlight for architects in tropical areas. This document also contains instructions for how to make blueprints by exposing, washing and drying the document. Collection: Océ Heritage Foundation, Venlo.

Research using oral history

The Invented from Copies study employs various oral history techniques. The research started with a collective moment shared with the public. In the Research Centre, surrounded by various reproduction types, we explored the role of reproduction in the design process with those involved and interested in this subject. In September 2020, an episode of Archive Explorations focused on the cross-disciplinary relationships between the use of zips in the 1970s in architectural design, animation and graphic design. We also interviewed former employees at architectural companies and reproduction companies, such as OCE, to collect, refine and test our knowledge and interpretations of copying processes and design and visualisation techniques.

Close-reading

Large numbers of reproductions and a high degree of uniformity invite close reading and comparison. This is the only way to notice differences, interpret them and relate them to each other on a larger scale. Reproductions require different ways of looking and examining than artistic sketches or presentation drawings, whose overall impression offers an easy understanding and needs no other documents for interpretation. With a copy and reproduction, it is precisely the details, such as annotations, a shifted line, a new colour, a question mark, a blemish or a different font, that reveal something about the copy's use and meaning in the design process. Such details and interrelationships mainly reveal themselves through close reading and comparison with contextual documents.

As supervisor of the Nieuwmarkt, architect Theo Bosch made a new proposal for the demarcation of a building block in Amsterdam on this photoreproductive print with annotations in red ink. He suggested the residents’ committee should give its opinion on the proposed boundary. He recorded these suggestions in the design process with a stamp and a date to clarify which steps were taken.

Preliminary insights

The Invented from Copies study is still in progress and will continue in 2022-23. Nevertheless, we can outline the first insights, which will also inform further research.

The photographic reproduction technique was introduced into architectural design practice around 1870 and had significant consequences. For the first time, architects could copy an architectural design without manual drawing and engraving. In a relatively short period, a giant leap forward was made in the production and distribution of the architectural design by means of blueprints, photoreproductive prints, Vandyke prints and electrostatic prints, whether or not combined with zips. The archives of Het Nieuwe Instituut thus contain many varieties of reproduction. Although we have never counted them, our research suggests at least half of the 1.5 million drawings are reproductions and copies, mixed media, or made and drawn for reproduction purposes.

This common practice of reproduction persisted well into the 1990s. Although design culture has almost wholly succumbed to digitisation, more recent archives show that some architectural companies, such as Michael van Gessel, de ArchitectenCie and OMA, still use analogue reproduction techniques as part of the design and thinking process. Therefore, this analogue reproduction practice has proved its endurance because it forms the DNA of Het Nieuwe Instituut's collection of analogue archives. The archive would not have existed in this form had architects not embraced the various photographic reproduction techniques so widely.

In this composite visualisation of De Flint theatre, industrial techniques have almost entirely replaced drawing. The document consists of glued-on and hand-drawn interior designs on tracing paper cut from an earlier drawing. We also see self-adhesive coloured plastic films and heat-resistant rub-down lettering from Letraset in Helvetica Medium font. This visualisation has been made for reproduction and appears in this dossier in smaller variants and varying contexts. Collection Het Nieuwe Instituut, archive O. Greiner, GREO 85203t2.

Follow-up research

We shall continue the archival research into blueprints, photoreproductive prints and zips in 2023. We shall then investigate what role analogue reproductions have had in the design process based on specific cases.

We shall also frame this historical research in the context of current and external perspectives. We aim to broaden, supplement or change the existing conceptual framework regarding reproductions. What topical issues inform our curiosity about architectural reproduction? Does a new look at history yield a different interpretation of current developments, such as digitising the design process? How do analogue reproduction techniques, such as blueprints and photoreproductive prints, function in contemporary art practice? The third perspective concerns perceptions of the copy in the context of cultural anthropology. Reproduction systems are not value-free systems. In a capitalist system, they are often coercive and inescapable, and in dictatorial and colonial systems, such as the former Dutch East Indies, they are instruments for exercising power. In this context, Invented from Copies, together with the OCE archive in Venlo, has started exploring sources related to the role of photoreproductive prints a and reproduced designs in the colonisation of the former Dutch East Indies.
