CxF stands for “Color Exchange Format”, an open XML format for the exchange of colour information, which is increasingly being implemented by software manufacturers to attach information on the colour behaviour and overprinting behaviour of spot colours to PDF files, for example. This information can then be read and interpreted by proofing software to optimize colour reproduction in a proof.
Ideally, the CxF/X file then describes the spectral measurements of the spot colours (on paper white and, to determine transparency, on black) and is used for colour communication and data exchange between customer, designer, agency and printer.
For the freieFarbe e.V. CIELAB HLC Colour Atlas the achieved spectral values of all colour fields are published as CxF3-file which can be used e.g. by colour manufacturers and software like InkFormulation from X-Rite.

PANTONE surveys users online about product and service direction
Today I received an email in which PANTONE asked how it should orientate its products and services in the future. The users were asked which countries, industries and company sizes they come from, but also what PANTONE products should look like in the future and what customers would be prepared to pay for PANTONE services in the future. Question: How much can PANTONE services cost? PANTONE appears to be orientating itself on the PANTONE Connect prices: All price queries have the lowest price category < $ 7,- / month, i.e. … read more

We passed the first proof certification for the 7C proof under FOGRA55
A few days ago Proof GmbH was the first company to be certified for proofing for the new 7C exchange colour space FOGRA55.

Precise proofing of tonal values of spot colours
In recent weeks, there have been lengthy discussions on the Fogra digital printing mailing list as to whether a research project should be launched to define standardised tonal value gradations for spot colours. What is this all about? In the field of CMYK and seven-colour printing, the definition of clear, printable and proofable standards is well established and has been tried and tested in practice. If the paper or paper class is known and defined, a measuring standard such as M0/M1/M2 has been established and the content of optical brighteners … read more
