Traditional blueprints became obsolete when less expensive printing methods and digital displays became available. The result is a copy of the original image with the clear background area rendered dark blue and the image reproduced as a white line. The unconverted coating is washed away, and the paper is then dried. When a strong image is seen the frame is brought indoors to stop the process. Where the India ink blocks the ultra-violet light the coating does not convert and remains soluble. Where ultra-violet light is transmitted through the tracing paper, the light-sensitive coating converts to a stable blue or black dye. The frame is put out into daylight, requiring a minute or two under a bright sun, or about ten minutes under an overcast sky to complete the exposure. The tracing paper drawing is placed on top of the sensitized paper, and both are clamped under glass, in a daylight exposure frame, which is similar to a picture frame. Engineers and architects drew their designs on cartridge paper these were then traced on to tracing paper using India ink for reproduction whenever needed. This is a simple process for the reproduction of any light transmitting document. Excess ammonium ferric citrate and potassium ferricyanide are then washed away. The image is then developed using a solution of potassium ferricyanide forming insoluble ferroferricyanide ( Prussian blue or Turnbull's blue) with the divalent iron. When the paper is illuminated, a photoreaction turns the trivalent ferric iron into divalent ferrous iron. The paper is impregnated with a solution of ammonium ferric citrate and dried. The best known is a process using ammonium ferric citrate and potassium ferricyanide. The blueprint process is based on a photosensitive ferric compound. It has almost entirely been replaced with digital computer-aided construction drawings. Practising engineers, architects, and drafters often call them 'drawings', “prints”, or “plans”. The term blueprint continues to be used less formally to refer to any floor plan (and even less formally, any type of plan). It was first largely displaced by the diazo whiteprint process, and later by large-format xerographic photocopiers. The process was not able to reproduce color or shades of grey. The blueprint process was characterized by white lines on a blue background, a negative of the original. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. He graduated with First Class Honours from the University of Liverpool, and gained his postgraduate diploma from the University of Westminster with Distinction, winning the Noel Hill Prize.A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. As part of this work, Keir represents the practice as part of the London Practice Forum, who's mission is to improve standards of practice and well-being within the profession.īeyond the practice, Keir undertakes outreach work with a rolling portfolio workshop programme with Blueprint for All and recently undertook a twelve week final year teaching programme at ETSAUN alongside Joe. He has lectured on benefits of collaborative working methods and in all team settings, advocates the open and transparent exchange of ideas and sharing of knowledge through collective research and debate. He is accustomed to working at a range of scales from direct stakeholder engagement on local community projects to delivery of major HQ buildings in central London.

In addition to this project focus, Keir leads specific agendas within the practice that include professional services, practice systems and QA working groups.īefore joining Morris+Company, Keir worked at award winning practices AHMM and Feilden Fowles and over the course of his career, he's gained experience designing with many types of client in both the public and private sectors. Since joining Morris+Company, he has led projects across a range of sectors including housing, education, workplace, and health. Keir is a highly adept and empathetic architect, and a certified Passivhaus designer.
