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.
Raster Image Processor (RIP) -
A combination of computer software and hardware that controls the printing
process by calculating the bit maps of images and instructs the printing device to create the images..
Most RIPs operate on PostScript.
Resolution -
The DPI or dots per inch of a design. Measured by how many dots or pixels are in one inch of a
design. The measurement of the fineness or detail. The higher the resolution the finer the detail in
an image
Satellites
- Small droplets of jetting fluid generated behind the main drop as the main drop detaches from
the nozzle.
Substrate
- Any surface on which printing is done.
Tagged Image File Format (TIFF)
- A standard graphic image file format often used for storing high
resolution images that can easily handle up to 24 bits of photographic image color.
Transmission Control Protocol/Internet Protocol (TCP/IP) -
is an open communications protocol
implemented on diverse systems and the Internet and is the preferred protocol for practical
interoperability.
Varnish -
A clear liquid coating applied to printed sheet for protection and glossiness.
Varnishing -
a finishing process whereby a transparent varnish is applied over the printed sheet to produce
glossy finish.
Viscosity
- the tendency of a liquid to flow slowly or quickly resulting from the friction of its molecules
