Type of Standards


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.

Demand Quality

When things don't work as they should, it often means that standards are absent.
