1 Scope
This part of ISO 12647 specifies a number of process parameters and their values to be applied when producing
colour separations and printing forms for newspaper single or four-colour printing.
The parameters and values are chosen in consideration of the process, covering the
process stages: “colour separation”, “making of the printing formed”, “OK print or
proof” and “production printing”.
This part of ISO 12647 is intended to enhance communication between printers, publishers and advertisers
and to make print buyers aware of the expected printed result in advance, enabling
them to plan accordingly. This part of ISO 12647 defines tolerances, allowing for objective quality evaluations and raising the competitiveness
of newspapers compared to other media.
This part of ISO 12647 is applicable:
-
— to coldset offset production printing on newsprint that use colour separation data;
-
— by analogy to press printing from printing surfaces produced by direct imaging;
-
— to line screens and non-periodic screens, parameters given can be applied by analogy.
Although this International Standard does not specify process control for flexographic
printing, digital printing systems or letterpress production printing, the production
aims defined by this International Standard may be applied when these printing technologies
are used and where the printing result is intended to be similar to that produced
by coldset offset lithography.
