Dot gain
Dotgain or Tonal Value Increase is the difference between the halftone values in the original and the halftone values in print. This difference is caused by printing technology.
Lexicon
Dot proof
In the case of a dot proof, the halftone screening of the final print is simulated in the proof. This screening shows possible moiré or other disturbing effects, that by dot proofing can be seen in advance on the proof.
EAN
EAN = European Article Number. The EAN has been replaced by the GTIN = Global Trade Identification Number in 2009.
Early binding
“Early Binding” workflow means that RGB image data are converted into the planned CMYK print colour space as early as possible during separation.
ECI
The European Color Initiative (ECI) is a group of experts, working on device independent processing of color data in digital publication systems. ECI has been founded in June 1996 in Hamburg at the initiative of the publishing houses Bauer, Burda, Gruner+Jahr and Springer.
EFI
Electronics For Imaging, Inc., short: EFI is an American company and one of the leading manufacturers of proofing systems worldwide: EFI Colorproof XF, since 2013: Fiery XF.

Film lamination
Film lamination is a thin foil coating which helps to protect the product (e.g. a book) from dirt and traces of use.
FM screen
With frequency-modulated screening (non-periodic screening), the halftone dots are distributed pseudo-randomly. Different tonal values result from the varying number of dots of the same size on one surface.
Fogra
Fogra Technology Research Association with headquarters in Munich is a service provider for the printing industry.
Gamma
Gamma is the graphical area the abbreviation for gamma correction, a non-standardized method of measurement of contrast for scanners, monitors and photographic materials.
Gamut
The gamut (also colour gamut) refers to the range of all colours in a colour space that can be recognised (camera, scanner) or reproduced (printer, monitor) by a device.
It is visualised in the form of a colour solid.
Gamut mapping
The conversion of colour values from one colour space (e.g. sRGB on the monitor) to another colour space (e.g. CMYK in print) so that the colour reproduction remains as consistent as possible.
GC1
GC1 refers to a coated primary fibre board (chromo board) in packaging printing.
GC2
GC2 refers to a coated primary fibre board (chromo board).
GCR
Gray Component Replacement is a variant of the color build-up in printing.
GD1
GD1 designates a coated secondary fibre board, insert and back grey
(chromo duplex board), top side wood-free white, with special volume (> 1.45 cm³/g).
