![]() 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. 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 has almost entirely been replaced with digital computer-aided construction drawings. 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. Our goal is to provide both actionable information and food for thought for wealth managers vying for competitive advantage in a highly challenging marketplace and tough overall economic climate.A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. ![]() ![]() We also offer comprehensive market-sizing, analyze the ongoing quest for long-term profitability the industry is facing, and outline eight initiatives-encompassing both the revenue and cost sides-that can help firms position themselves optimally for the future. In this report, BCG’s 23rd annual study of the global wealth management industry, we address how wealth managers are reacting to the present turbulence, call out developments that may surprise industry observers-such as interest income from deposits overcompensating for declining investment-fee revenues in many regions-and take a detailed look at how wealth managers have performed in different areas of their businesses. How can these players achieve ongoing, profitable growth in this volatile era-a time further characterized by intensifying customer demands for higher and more efficient service levels? Such daunting conditions have made it that much more important for both incumbent and rising players to have a clear roadmap for the rest of the decade. The prospect of consistent business growth became increasingly difficult to envision on the horizon. What had been a steamroller of global financial wealth expansion began to develop engine trouble in 2022, with booking centers undergoing major power shifts. The past few years have been difficult for many industries, and wealth management is no exception.
