Shown below are the definitions for: I
 |
idler rollers Any free turning roller/roll in a web press used to support and guide the web as it travels thru the press. Often times the roller has a rough or "grated" surface, to minimize tracking and smearing of freshly printed surfaces and to aid in gripping and guiding the web of paper.
|
illumination See "standard illumination".
|
image density A perception of the image darkness as detected by the eye or measured by a reflection densitometer; see reflectance.
|
imposition The proper placing of pages on a layout for printing, such that the pages will appear in proper sequence in the signature after folding.
|
impression cylinder The cylinder against which impression is made: used to create the pressure required to transfer the image from the blanket (or plate) to the paper surface.
|
impression The pressure (see "back pressure") or the print left by the press plate or blanket when it comes into contact with the paper.
|
indirect printing See "offset".
|
ink fountain The reservoir from which ink is metered to the ink rollers on the printing press.
|
ink jet printing Also "jet" printing; pressureless and plateless forms of printing, generally where a variable image is generated from an electronic media or computer. The digitized information generating the image "triggers" the squirting or deflection of a very fluid liquid ink through one or more nozzles onto the paper surface: can be likened to graffiti spray can painting.
|
ink receptivity See "K & N" ink receptivity.
|
ink trapping See "trapping".
|
inkometer See "tack".

|
I.G.T. A laboratory printing device that uses special fluids or inks for assigning numerical values to the measurement of surface strength; see picking. The I.G.T. abbreviation is for the Amsterdam Holland manufacturer of the equipment: "Instituut voor Grafische Techniek".
