\"\"<\/a>I guess most users of ISO 12647\/2 will either use the Fogra 39 based \u2018ISO coated v2\u201d profiles from the ECI<\/a> (European Color Initiative) or Adobes \u2018Coated FOGRA39 (ISO 12647-2-2004)\u2019 profile which is in the later versions of Adobe CS and used by their color settings file \u2018Europe Prepress 3\u2019.<\/p>\n

\u00a0Just to mention an on-going irritation at this point. These profiles, and often printing to ISO 12647\/2, are referred to as using Fogra 39! This is not correct. Fogra 39 is a colour management data set created by Fogra by printing colour management target patches to the requirements of ISO 12647\/2 on coated paper, then measuring the result using colour management software to produce a colour data set. In this case called Fogra 39!<\/p>\n

\u00a0This colour management data set is freely available from the ECI web site, so anyone can use it to make an \u2018ISO coated v2\u2019 ICC profile. This is what both Adobe and the ECI have done. Fogra 39 therefore is not a standard or a ICC profile, but part of the toolset that is needed to print to the standard on coated papers.<\/p>\n

\u00a0So end of a minor rant and back to the point, do you need more then one ICC profile based on Fogra 39 for printing on coated paper for ISO 12647\/2?<\/p>\n

\u00a0Yes, I believe you may. Differing images, lighter weight papers and older presses will benefit from using profiles with different TAC (Total Area Coverage) of ink and higher GCR (Grey Component Replacement) for stronger black separations.<\/p>\n

\u00a0Four colour black and white images will be more stable if an ICC profile is used with a higher GCR then the \u2018standard\u2019 ISO coated v2 profiles. Lighter weight coated papers we be more stable on press if lower TAC profiles are used. It this case less ink film weights will result is less paper stretch and deformation and quicker drying.<\/p>\n

\u00a0If presses are a little unstable or have less then optimum inking, the use of lower TAC and higher GCR, resulting in stronger black separations will make any colour variation and registration issues less noticeable.<\/p>\n

\u00a0Higher GRC and lower TAC can also reduce ink consumption, so lowering costs. Just work how much extra turnover you would need to match \u00a0savings of just 5%-10% reduction in ink costs that using these profiles could give. Also using lower TAC based profiles can result in less paper deformation on light weight papers, faster drying and less marking. Also often less, or even no seal is needed.<\/p>\n

\u00a0So how to implement the use of other Fogra 39 based profiles? Well, you can download the For a 39 dataset and make your own profiles using colour management software from the usually suspects. Also a number of companies and organisations such as Basicolor<\/a> and VIGC<\/a> have produced such profiles, which are freely available.<\/p>\n

\u00a0Please see my blog<\/a> on the VIGC profiles.<\/p>\n

\u00a0If you are unsure about the use and application of these profiles it may be best to talk to a colour management consultant. I know a good one J.<\/p>\n

\u00a0Finally, I have discussed this areas using other Fogra 39 based profiles as a basis, but of course this concept also applies to other profiles and printing conditions such as uncoated papers, and there are also profiles based on the Fogra 47 data set for whiter uncoated papers that can offer the same benefits.<\/p>\n
