Concentric multi-colored rings caused by the pressing of film to glass. This can be a problem in scanning from negatives or transparencies.
In reproduction from either photography or lithography, an objectionable series or irregularly colored circles caused by the prismatic action of interfacing different smooth surfaces together, such as in contact frames or transparencies on a scanner drum.
An interference pattern created at the meeting point of two refracting surfaces. When exposing a polymer plate in a vacuum frame, the even distribution of pressure can be controlled by watching the Newton rings. When the vacuum is evenly distributed throughout the frame, the entire plate is covered with tiny Newton rings.
Colored, ring-shaped patterns that appear between two transparent tightly pressed surfaces like glass or film. Caused by moisture between the surfaces refracting the light.
A series of concentric circles that appear on a scanned image when a thin layer of air exists between the glass scanner bed and the image being scanned. Newton rings appear when light waves are reflected from both top and bottom surfaces of the air between the glass and the image, interfering with the resulting scan. To resolve this problem, Microtek developed the patented Emulsion Direct Imaging Technology (E.D.I.T.) for its scanners.
Concentric multicoloured rings that occur when film is in contact with glass; a problem in scanning from negatives or transparencies.
