A defect, that is within an image. It can mean something on the graphic that was not
intended, or something missing that was intended. All image quality defects are arti-
facts.
An electronic adjustment, that ensures that a printer can coordinate left to right, with
right to left, printing.
The print head at it's stand by position, with the cap mechanism sealing the nozzles.
The top layer of graphics paper (media) that consists of a special substance
designed to trap ink and keep it from being absorbed into the paper fibers. Non-paper
based ink jet media uses coating to allow the ink to bond with the surface. A coatings
purpose is to minimize dot gain, and control saturation.
An unintended change of a gradient or tone.
The qualities of a photograph that makes an image appear real. The smooth and life-
like transition from one color shade to the next, like in a photograph. Epson Ink Jet
printers are not continuous tone printers. But when working properly, their printed
images fool the human eye into seeing continuous tone transitions.
A term that refers to unintended ink on the page deposited by debris dropping from
the print head.
A nozzle is firing, but the ink drop is not landing where it is intended too. Irregular
spacing on the nozzle check pattern indicates this condition.
The dot pattern placed on the printed surface to create and image. Also known as
screening.
A drop of ink tends to travel out from its point of impact, as the media absorbs it. The
purpose of the coating (on the media) is to minimize dot gain.
