122 A keystroke or combination of keystrokes that allows you to quickly accomplish common tasks. Back to TOC An undesirable pattern in color printing that results from incorrect screen angles of overprinting halftones. Moire patterns usually result when you scan a halftone, when you scan images taken directly from a magazine, or when you scale an image in an image editor after it is scanned. The orientation of a photograph or image that is wider than it is tall. When an image is taller than it is wide, it is called portrait orientation. This option enables higher bits per pixel when the scan is sent to the software. When it is off, 8 bits per pixel are returned for grayscale and 24 bit for color. When it is turned on, 16 bits per pixel are returned for grayscale and 48 bits for color. The gray shades of an image. Midtones are usually between 30% and 70% black. Midtone control adjusts the brightness of gray levels in the image so that the lightest and darkest portions of the image can be properly displayed on your monitor. The higher the setting, the brighter the image appears on your monitor. The cutout that comes with the optional transparency adapter that is placed on the scanning glass. Negatives are then placed in the template. This option reduces the noise (unwanted specks) in an image by applying software algorithms to minimize the effects of noise in the scanner electronics. See optical character recognition. Abbreviated OCR. A technology that recognizes letters in a scanned image and converts them into ASCII characters, or editable text.
