Digital printers or materials 72 inches or greater in width.
The physical components of a computer system, including any peripheral equipment such as printers, modems, and mouse devices.
A file or set of data that applies values to maintain color consistency from device to device. icc stands for international color consortium, the forum responsible for the standards.
An acronym for input/output. the complementary tasks of gathering data for a computer program to work with and of making the results of the computer's activities available to the user or to the other computer processes.
Ink level sensor
Float switch in secondary ink tank that senses the ink level in the tank.
The pump that moves ink from the primary ink tank to the secondary ink tank.
Ink supply tubes
Long polyethylene tubes between the ink pumps and the print heads.
A type of printer that sprays tiny streams of quick-drying ink onto a substrate.
The cable that interconnects the image computer and the vutek printer.
The polyethylene tube that is between the secondary ink tank and the jet.
Horizontal stripes of any width found in the printed image.
The toothed metal gear by which the carriage motor turns the drive belt.

A nylon skeleton shield used to support and protect the tubes and cables running between the printer and the carriage.
The orifice located on the jet assembly that is used to discharge a stream of atomized ink droplets.
A scalable image that can be enlarged or reduced without loss of detail.
An acronym for pixels per inch. a measure of resolution in a digital image or computer display.
An acronym for postscript®. a page description programming language created by adobe. it is a device–independent industry standard for outputting documents and graphics.
the preferred technology for an inkjet print head, primarily because of its durability. the technology uses piezoelectric materials located near the ink reservoir of each nozzle. as electric charges are applied, the material vibrates inward and forces a tiny amount of ink out of the nozzle. when it vibrates out, it pulls more ink into the reservoir.
small white spots on the image, 1 mm or less in diameter, appearing in groups.
A page description programming language created by adobe. it is a device–independent industry standard for outputting documents and graphics.
Primary ink tank
The plastic tanks located in the ink cabinet.
An internal computer that is used to control all printer operations.
Printer power supply
A large enclosed assembly located in the rear of the controller compartment used to supply a variety of dc voltages to the printer.
To flush ink through the system to release any obstructions in the system.
An acronym for radio frequency interference. this is noise introduced into an electronic circuit, such as a radio or television, by electromagnetic radiation produced by another circuit, such as a computer.
An acronym for raster image processor. the hardware/software that takes individual pixels in a digital file and breaks them down into individual cmyk dots that a press or printer can read for output. rip quality is very important; when assessing a rip, look for image quality, speed and functionality.
An accepted standard for serial communications between two computer devices, e.g. the printer and a computer.
An acronym for Raster Translation Language. RTL, a subset of hpgl/2, is a format used for driving color printers.
Precision rails on which the carriage traverses.
The process of rendering an image or page, pixel by pixel, in a sweeping horizontal motion, one line after another.
An image that is defined as a collection of pixels arranged in a rectangular array of lines of dots or pixels.
Raster Image Processor (RIP)
The hardware/software that takes individual pixels in a digital file and breaks them down into individual CMYK dots that a press or printer can read for output. RIP quality is very important; when assessing a RIP, look for image quality, speed and functionality.
Raster Transfer Language (RTL)
The language commonly used to output data from a RIP and transfer it to the digital printer. the printer picks up the rtl data and outputs the information.
The number of pixels (picture elements) per unit of linear measurement (inch) on a computer monitor or the number of dots per inch in output form.
An acronym for standards for web offset printing. this is a specification used to establish a method of reproducing process color with predictable results.
