Basis: DIS/ISO 12647-3:2004
Ref.: Newspaper offset (coldset) and proof printing on standard newsprint
The revised version of ISO 12647-3:2004, the standard for the newspaper offset printing process, is largely complete. The most important change is that the existing varying dot gain values for different processes have been replaced by a single, process-independent dot gain. Agencies and ad suppliers can now supply all newspapers in the US with a single CMYK data set, separated in accordance with ISOnewspaper30v4.
The introduction of the process-independent dot gain and corresponding standard newspaper profile is intended to make newspaper houses more customer-friendly. However, the direct further processing/printing of CMYK data separated in accordance with ISOnewspaper30v4 presupposes the conversion/adaptation of the in-house processes at the newspaper operations on the basis of DIS/ISO 12647-3:2004, or the adjustment of the data reception and following aligning of all internal processes. The objective of the standardisation is to obtain consistent colour printing at a high quality level in all newspapers.
The ZMG and Ifra newspaper printing quality initiative (QUIZ), a project supported by the Federal German printing and media association (bvdm), published a standard profile and two special profiles for international newspaper printing for the first time in March 2001. Since then, the concept of connecting printing standardisation based on ISO 12647-3 and colour management has proven successful. Many newspaper houses and ad suppliers support it and have used the published ICC colour profiles for newspaper printing for many years.
Ifra has been able to build on the experience gained from numerous national and international standardisation projects and incorporate its findings into the new ISO newspaper-process standard. Thus the original QUIZ profiles from the year 2001 were continually replaced by new and better adapted profiles.
The name of the new Ifra standard profiles for newspaper printing is:
ISOnewspaper30v4.icc, colour profile
ISOnewspaper30v4_gr.icc, grey scale profile
These profiles have been tested successfully in practice by various newspaper operations. The new standard profile is available for downloading from this web site with immediate effect.
The profiles correspond in principle to the existing standard profiles and the visual results they achieve. All those who to date have used the standard profile
"Newsp_Col (or Gr)_Prof_22 2.03V2 (orV3).icm or Newsp_Col_(or Gr) Prof_28 2.03V2 (orV3).icm" should use this profile in the future. It differs from the existing profile by the following details:
- Compensation of a dot gain of 30 %.
- Orientation towards adapted primary and secondary colours of the new DIS/ISO 12647-3:2004.
- Characterising data were recorded on a white measuring background.
- Maximum GCR.
From this colour profile, a grey profile was additionally produced that is made available under the name "ISOnewspaper30v4_gr.icc". For example, the grey profile can be used for the automatic conversion of colour images into grey scale images in image processing programs, preflight systems or colour servers.
ISOnewspaper30v4.icc was compiled taking into account the specifications and recommendations of ISO 12647-3:2004. A maximum GCR was used for separating in order minimise colour fluctuations in print (see Ifra Special Report 2.16). At the same time care was taken to ensure that no greying occurs in sensitive skin tones. Detailed separation parameters are included in "readme" attached to the profiles.
ISOnewspaper30v4.icc is based exclusively on colour measurements on a white measuring background. A black measuring background is, in accordance with ISO/DIS 12647-3:2004, only permissible for process control in print. Targets and tolerances for checking print against black are listed in "DIS_ISO 12647-3_2004_e.pdf". The properties of the white measuring background are standardised. See www.fogra.org for information on which papers and materials are suitable as a basis for carrying out standardised measurement on devices with black measuring table.
If possible, for measuring data for the production of profiles for proofing instruments, a white background should also be used in order to ensure compatibility with print profiles and colour matching conditions.
