- Root

- Root Nameserver
A root nameserver is a DNS server that answers requests for the root namespace domain, and redirects requests for a particular top-level domain to that TLD’s nameservers.
Although any local implementation of DNS can implement its own private root nameservers, the term “root nameserver” is generally used to describe the thirteen well-known root nameservers that implement the root namespace domain for the Internet’s official global implementation of the Domain Name System.
All domain names on the Internet can be regarded as ending in a full stop character e.g. “en.wikipedia.org.”.
This final dot is generally implied rather than explicit, as modern DNS software does not actually require that the final dot be included when attempting to translate a domain name to an IP address.
The empty string after the final dot is called the root domain, and all other domains (i.e. .com, .org, .net, etc.) are contained within the root domain.
When a computer on the Internet wants to resolve a domain name, it works from right to left, asking each nameserver in turn about the element to its left.
The root nameservers (which have responsibility for the . domain) know about which servers are responsible for the top-level domains.
Each top-level domain (such as .org) has its own set of servers, which in turn delegate to the nameservers responsible for individual domain names (such as wikipedia.org), which in turn answer queries for IP addresses of subdomains or hosts (such as www).

- Rub-Off
The phenomenon by which pressure on stacked sheets causes ink on one surface to be smeared on to the next.
This “carbon-copy effect” can occur due to the pressure of the clamp in trimming machines.
- Rubbed
Refers to condition; the spine or cover has visible scuffmarks and may be worn in places.
- Rubber Blanket
The blanket wrapped around the cylinder that is essential to the offset printing process. It transfers the printed image from the forme onto the paper.
The term “offset” is derived from the process by which color is displaced onto the rubber blanket.
Printing over a blanket provides an even print surface which makes it possible to work with coarse and granular papers.
- Rubel, Ira Washington
Considered the inventor of the offset printing process.
The owner of a small print shop in New Jersey, in 1903 Rubel accidentally discovered that he could obtain better results with indirect printing using a blanket cylinder than with direct printing.
He covered the impression cylinder of a printing press with a rubber blanket and paper sheets were then fed incorrectly several times during a printing run.
The impression from the printing forme ended up on the rubber blanket and from there was passed on to the back of the sheet.
Rubel discovered that these misprints were of a better quality than the regular prints, and consequently went on to develop the first offset printing press.

Rubylith
A transparent reddish material applied to a clear acetate sheet.
It photographs as opaque so it can be used to block out areas on a flat that should not appear on a particular negative or plate.
It is also used to add cut out areas to a flat that can have an image or halftone negative placed in the cut out to be exposed to the plate.
The cut out area is manually cut into the red transparent material and then the material is peeled off from the acetate sheet, leaving a clear opening in the rubylith.
The cut out area can also be used to expose the shape of the cut out, as a solid or with a screen placed behind it, directly to the plate to manually add an image to the plate.
Used for such purposes as adding screens to the image or a color to a logo.

- Rule
-
A straight line used as a graphic element.
-
The thickness of the line is measured in points.
-
A continuous line, thick or thin, that is used in decorative printing.
In the 1800s and early 1900s, title pages were often enclosed in plain rule-borders.
The term can also apply to a decorative line on a binding, which may be in blind or gilt.
-
- Rule Weight
Thickness of the rule measured in points.
- Runaround
Running text so that it fits around an illustration or other element.
- Runnability
The paper’’s ability to hold ink on the surface consistently, to absorb ink uniformly, its dimensional stability, and its surface texture all affect how well a paper will run on the press.
- Running Charge
Charges that are directly related to the cost of production, generally figured on per M basis.
It can include materials, press time, other machine operations and miscellaneous labor.
- Running Directions
The direction through which paper is passed through the paper machine, generally the same as the grain direction.
The running direction is often indicated by an arrow on sheet packages. See also grain direction.
- Running Foot
A line of text that appears at the bottom of almost every page of a section or document.
- Running Head
A title used at the top of each page in a book.
