Optical Character Recognition Paper. Similar to MICR Paper, a high-quality bond paper of good surface and dimensional stability for printing with characters for computer recognition.
OFF-MACHINE COATED PAPER
Base paper to which a mineral coating has been applied on a coating machine separate from the papermaking machine.
A covering for a cylinder on a printing machine for accepting the ink image and then relocating it to the surface to be printed.
See Dry Offset.
The transfer of an inked image from a plate to a blanket cylinder, which in turn transfers the image to the printing material as it passes between the blanket and the impression cylinder and pressure is applied. Also referred to as offset lithography.
A device on the feed board of a printing machine for controlling the lateral alignment of the printing paper opposite to the operating side of a printing machine.
ON-MACHINE COATED PAPER
Paper that has been coated with mineral matter by coating equipment installed as an essential part of the papermaking machine.
A procedure of covering the surface(s) of a paper with one or more layers of coating slip or other materials in fluid form, without recourse to a separate operation, the necessary equipment being an integral part of the making machine.
The extent to which a paper is capable of obscuring matter printed on the opposite side, an underlying page or other surface.
See Fluorescent Whitening Agent.
OUT TURN SHEET
A sheet of paper, taken during manufacture, that functions as a reference for the mill or client.
This invention is a process for maintaining pulp viscosity while enhancing brightness during the oxygen bleaching stage or stages of pulp preparation in the manufacture of paper comprising adding an effective amount of melamine to paper pulp prior to the oxygen bleaching stage.
Ozone bleaching offers the ability to close a mill’s water system and produce totally chlorine-free pulp. To ensure the lowest evaluated cost of supplying a mill with ozone, a total mill impact study must be conducted considering the overall oxygen and ozone requirements and fiber line constraints.
