ISO 15930-9:2020 グラフィックテクノロジー— PDFを使用したデジタルデータ交換のプリプレス—パート9：印刷データの完全な交換（PDF / X-6）およびPDFを使用した外部プロファイル参照（PDF / X-6pおよびPDF / X-6n）との印刷データの部分的な交換2.0 | ページ 6

3.1

characterized printing condition

printing condition for which process control aims are defined and for which the relationship between input data and the colorimetry of the printed image is documented

Note 1 to entry: It is generally preferable that the process control aims of the printing condition and the associated characterization data be made publicly available via the accredited standards process or industry trade associations.

3.2

CMYK

subtractive process colour model where the channels are called Cyan, Magenta, Yellow and Black

3.3

compound entity

unit of work with all text, graphics and image elements prepared for final print reproduction that might represent a single page for printing, a portion of a page or a combination of pages

3.4

conformance level

identified set of restrictions and requirements with which files, processors and writers are required to comply

3.5

default colour space

PDF colour space named DefaultGray, DefaultRGB or DefaultCMYK that provides an indirect method of specifying the colour space of elements

3.6

element

substructure of a compound entity relative to the current processing environment, such as a block of text, a contone picture or an outline graphic that, by itself, comprises the smallest logical composed unit of a compound entity

3.7

n-colourant

process colour model other than gray, RGB (3.12) or CMYK (3.2) , and comprising at least two colourants

3.8

non-print element

element (3.6) not intended for final print reproduction

3.9

print element

element (3.6) intended for final print reproduction

3.10

process colourant

additive or subtractive colourant whose characteristics (colour, transparency, etc.) make it suitable to combine with other colourants to form secondary or tertiary colours

3.11

process colour model

colours, defined in a colour coordinate system, produced by a set of process colourants (3.10)

3.12

RGB

additive process colour model (3.11) where the channels are called Red, Green and Blue

3.13

spot colour

single colourant, identified by name, whose values are specified independently from the colour values specified in a colour coordinate system

3.14

trapping

modification of boundaries of colour areas to account for dimensional variations in the printing process by overprinting in selected colours at the boundaries between colours that might inadvertently be left uncoloured due to normal variations of printing registration

Note 1 to entry: Trapping is sometimes referred to as chokes and spreads or grips. This is not the same as ink trapping.
