This had been used by Zeiss-Ikon in their mid-level cameras of their Contaflex series, and by Kodak in early interchangeable lenses for the top-end Retina series (later going to full lenses). Canon offered four lens options: 35mm f/3.5, 50mm f/1.8, 95mm f/3.5, and 125mm f/3.5.
An inkjet printable DVD is a DVD made with an inkjet ink permeable coating on the upper, non-recording surface of the DVD. This allows compatible CD/DVD inkjet printers to print directly onto the disc. Inkjet printable DVD media offers a way to customize DVD-Rs. [1] [2]
The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures. [4] Others are part of a polymer structure. [5]
Superabsorbent polymer powder. A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.
The pressure swing adsorption (PSA) process is based on the phenomenon that under high pressure, gases tend to be trapped onto solid surfaces, i.e. to be "adsorbed". The higher the pressure, the more gas is adsorbed.
Unlike spirit duplicators (where the only ink available is depleted from the master image), mimeograph technology works by forcing a replenishable supply of ink through the stencil master. In theory, the mimeography process could be continued indefinitely, especially if a durable stencil master were used (e.g. a thin metal foil).
India ink – a type of ink; Ink – a substance used to stain or dye; Ink blotter – a pad used to absorb excess ink; Inkpot – a low-lying bottle used to hold ink; Inkwell – a low-lying bottle used to hold ink; Iron gall ink – a purple-black or brown-black ink made from iron salts and tannic acids
Older ink erasers are therefore small knives designed to scrape off the top few microns of a sheet of paper, removing the ink that had penetrated. In concert with bladed ink erasers, an eraser similar to those at the end of pencils was also used, with additional abrasives, such as sand, mixed into the rubber.
