Biography:

 Wallpaper is a kind of material used to cover and decorate the interior walls of homes, offices, and other buildings; it is one aspect of interior decoration. It is usually sold in rolls and is put onto a wall using wallpaper paste. Wallpapers can come plain as 'lining paper' (so that it can be painted), textured (such as Anaglypta), with a regular repeating pattern design, or, much less commonly today, with a single non-repeating large design carried over a set of sheets.
Wallpaper printing techniques include surface printing, gravure printing, silk screen-printing, rotary printing, and digital printing. Wallpaper is made in long rolls which are hung vertically on a wall. Patterned wallpapers are designed so that the pattern "repeats" and pieces cut from the same roll can be hung next to each other so as to continue the pattern without it being easy to see where the join between two pieces occurs.

 In the case of large complex patterns of images this is normally achieved by starting the second piece halfway into the length of the repeat, so that if the pattern going down the roll repeats after 24 inches the next piece sideways is cut from the roll to begin 12 inches down the pattern from the first. The number of times the pattern repeats horizontally across a roll does not matter for this purpose.[1] A single pattern can be issued in several different colorways.Wallpaper, using the printmaking technique of woodcut, gained popularity in Renaissance Europe amongst the emerging gentry. The social elite continued to hang large tapestries on the walls of their homes, as they had in the Middle Ages. These tapestries added color to the room as well as providing an insulating layer between the stone walls and the room, thus retaining heat in the room. However, tapestries were extremely expensive and so only the very rich could afford them. Less well-off members of the elite, unable to buy tapestries due either to prices or wars preventing international trade, turned to wallpaper to brighten up their rooms.Historical examples of wallpaper are preserved by cultural institutions such as the Deutsches Tapetenmuseum (Kassel) in Germany;the Musée des Arts Décoratifs (Paris) and Musée du Papier Peint (Rixheim) in France;[2] the Victoria & Albert in the UK; the Smithsonian's Cooper-Hewitt.

New digital inkjet printing technologies using ultraviolet (UV) cured inks are being used for custom wallpaper production. Very small runs can be made, even a single wall. Photographs or digital art are output onto blank wallpaper material. Typical installations are corporate lobbies, restaurants, athletic facilities, and home interiors. This gives a designer the ability to give a space the exact look and feel desired.In 2012, Scientists at the Institute of Solid Construction and Construction Material Technology at the Karlsruhe Institute of Technology announced that they had developed a wallpaper that can help keep a masonry wall from failing in an earthquake. The wallpaper uses a special adhesive which forms a strong bond with the masonry when dry.
