- Ragged Left/Right:
Successive lines of type which are of unequal length and are aligned at the opposite hand column (e.g. rigged right is aligned on the left and ragged on the right).
- Random Access Memory (RAM):
RAM temporarily “holds” programs and files while in use.
- Raster Image Processor (RIP):
A device or program that translates the instructions for a page in a page description or graphics output language to the actual pattern of dots (bitmap) supplied to a printing display system (i.e. film or printing plate).
- Record:
In a database, one complete entry consisting of one or more fields of data.
- Reflective Art:
Originals such as photographs or illustrations which are on a reflective surface as opposed to transparent film.
- Register (Registration):
To fit two or more printing images on the same paper in exact alignment with each other. The correct positioning of one color over another during the printing process. (a.k.a. fit)
- Registration Marks:
Crosses or other targets applied to imaged document to ensure proper alignment of all color plates when printing on press.
- Relative Colorimetric Rendering Intent:
A rendering intent that determines how a file’s color values will be remapped from the current color space into the target color space; in this case any color that is not outside of the target color space (usually that of an output device) is remapped to an exact match; however, out-of-gamut colors are moved to the nearest edge of the target color space, which means they will be clipped.
- Rendering Intent:
Each device has a fixed range of color it can reproduce. The range of color a device can reproduce is called its color gamut. Colors that can be produced in the source color space but aren’t reproducible in the destination color space are called out-of-gamut colors. The ICC profile specification includes four different methods of handling out-of-gamut colors; these methods are called rendering intents. These four rendering intents are: Perceptual, Relative Colorimetric, Absolute Colorimetric, Saturation.
- Repeatability:
The ability to keep photo film and the images thereon in proper register.
- Resolution:
How resolution is defined in electronic imaging will depend upon what item is being referred to. Output devices, including presses, print with dots, so the resolution in their case is described as being dots per inch (DPI). On the other hand, digital images, whether obtained with a scanner or digital camera, are made up of pixels, so their resolution would be defined as being pixels per inch (PPI). Monitor resolution is also defined as pixels per inch (PPI) due to its display of electronic files in pixels. Scanner resolution is referred to as samples per inch (SPI) due to a scanner’s method for digitizing reflective art and/or transparencies, which is to sample the original at a particular frequency – a higher sample rate (like 300 SPI) means a higher scanning resolution than 150 SPI, which is only half that of 300 SPI. The higher the sample rate (samples per inch), the more closely the scan will represent the original’s appearance due to it having more samples from which to construct its representation of the original.
- Reverse:
Type or graphic that appears as white on a black or dark colored background.
- RGB:
Acronym for Red-Green-Blue, the primary colors of the additive color model, which describes how monitors and RGB digital images represent color by blending these three primary colors together. When all three are combined over each other the color of light is white.
- Rosette Pattern:
The pattern created when all four CMYK color halftone screens are printed at traditional angles, shown to produce the best results in printed color output. The rosette pattern is noticeable only under magnification.
- Rule:
A straight line of any thickness or a line used as a graphic element to separate or organize copy.
- Run Around:
Type that wraps around a picture or art. Also known as Text Wrap.
- Run:
A group products (versions) that are printed together. There may be more than one run per press ticket.
