Hypertext Markup Language (HTML) - A series of formatting commands that describes the components of
graphics and text material presented on the World Wide Web in a consistent manner
Image Area - Portion of paper on which ink can appear.
Image - Usually a photograph that is “translated into a bitmapped” image by scanning Ink Jet Printing
Method of printing by spraying droplets of ink through computer-controlled nozzles. Also called jet printing.
Initialization File - A file, usually with the extension .INI, that sets startup variables for an application
program.
Large Format Printing - refers to large sized prints, typically A1 sized or larger, produced in full color
utilizing full color digital ink jet printers.
Materials Safety Data Sheet (MSDS) - This is a document which describes the potential safety hazards of a
chemical, liquid or solid, and instructs how to handle it safely and how to respond to exposures or spills.
Meniscus - The curved surface at the top of the water column, or at any interface between a liquid and a
solid. Nozzles have a meniscus, whose shape and position are set by a slight negative pressure in the jets at
rest, balanced against the surface tension of the liquid.
Meniscus Pressure Used at Spectra - the meniscus pressure often refers to an inward bubble pressure
that equals the fluid pressure at a print head jet nozzle when that jet is not activated. A negative meniscus
pressure is applied to inactivated jets only when the print head system is operating, helping to prevent the
jetting fluid from leaking at the nozzles. More generally, meniscus pressure is the negative pressure created
behind a meniscus, due to surface tension.
Portable Document Format (PDF) - An electronic document format from Adobe that allows the distribution
of digital files across any platform that can display a document as originally designed and formatted without
having the software application or fonts on the viewing computer.
Pigment - Particles that absorb and reflect light and appear colored to our eyes; the substance that gives ink
its color.
Pixel - A single dot on a monitor or on digital image.
Print head - part of a digital printer that is directly responsible for applying ink to a substrate
Protocol - The set of conventions defining communication between electronic components, for example, and
a host computer and its interface. The way information is placed on a network. The steps needed to
communicate or activate an operation or exchange of information in or between computers.
Purge - Performed for a variety of print head maintenance reasons, a purge is a regulated pressure applied
for a fixed amount of time at the air interface to the ink reservoir attached to the print head jetting assembly
to force ink, along with air bubbles and debris if present, out the jets through the nozzles.
Raster - A line of pixels. Also the process of rendering an image or page, pixel by pixel, in a sweeping
horizontal motion, one line after another.
Rasterization - The process of converting mathematical and digital information (vector commands) into a
series of dots by an output device.
