Decrease in rag fibre quality may be a culprit; as demand for paper rose in later centuries, papermakers used less water and spent less time cleansing the rag fibres used to make paper. [4] An early work of art to have been affected by foxing is the Portrait of a Man in Red Chalk , a drawing on paper by Leonardo da Vinci .

Other names include fan-fold paper , sprocket-feed paper , burst paper , lineflow (New Zealand), tractor-feed paper , and pin-feed paper .
Waterproof paper uses special coatings (plastic-coated paper) and fibers to enhance durability, dimensional stability, tear resistance and resistance to changing shape or texture when exposed to water. The paper has applications for wet or damp environments, including outdoor, marine, field uses as well as printing applications for similar ...
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses, herbivore dung, or other vegetable sources in water. Once the water is drained through a fine mesh leaving the fibre evenly distributed on the surface, it can be pressed and dried.
Carbonless copy paper has micro-encapsulated dye or ink on the back side of the top sheet, and a clay coating on the front side of the bottom sheet. When pressure is applied (from writing or impact printing), the dye capsules rupture and react with the clay to duplicate the markings made to the top sheet.
Hogan spoke at the RNC shortly before Donald Trump was set to accept the party’s nomination and delivered one of the most energetic speeches of the convention, calling Trump his “hero” and a ...
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
Acidic paper is paper which was manufactured using acidic substances. [1] Widely used since the mid-nineteenth century, its pages become yellow within years, extremely brittle over decades, and eventually unreadable in the library and archive collections intended to preserve them. [ 2 ]
