The portal for colour binding proofs, colour proofs, digital proofs, online proofs. Compact knowledge on colour management, graphics, measuring technology & more.
D65 is standardized viewing condition with 6500 K color temperature. It is the default setting for most monitors and is mainly used in color matching etc. for websites, so in media that are considered primarily to be viewed on the monitor.
In the printing industry, the standard light is D50 according to ISO 3664: 2009 standard, a warmer light than D65 with 5000 Kelvin color temperature, which is also used for color matching on the press and in the evaluation of proofs.
Delta-E is a unit for the colour distance between two colours.
Densitometers measure colour density and optical density. Reflected light densitometers measure prints or photographic prints, while transmitted light densitometers measure films for printing plates or screen printing, slide films and negative films.
A design grid is an auxiliary construction and helps to place the texts, pictures and graphics in the layout. It serves to standardize the document.
A DeviceLink conversion is a colour management process in which a direct colour transformation is carried out between two colour spaces.
A digital proof (correctly: contract proof) is an ISO 12647-7-certified testing device for the graphic arts industry. A digital proof simulates the colourfulness of offset printing or gravure printing in a colour and legally binding manner within the narrow tolerances of the ISO standard.
Digital proofs (correct: contract proofs) are an ISO-certified test equipment for the graphic arts industry. Digital proofs simulate the colourfulness of offset or gravure printing in a colour and legally binding manner within the narrow tolerances of ISO 12647-7. Today, they are almost exclusively calculated using a RIP and then produced with inkjet printers on special proof papers.
Dotgain or Tonal Value Increase is the difference between the halftone values in the original and the halftone values in print. This difference is caused by printing technology.
In the case of a dot proof, the halftone screening of the final print is simulated in the proof. This screening shows possible moiré or other disturbing effects, that by dot proofing can be seen in advance on the proof.
EAN = European Article Number. The EAN was replaced by the GTIN = Global Trade Identification Number in 2009.
“Early Binding” workflow means that RGB image data are converted into the planned CMYK print colour space as early as possible during separation.
The ECI – the European Color Initiative – is a group of experts who deal with the processing of colour data in publication systems.
Electronics For Imaging, Inc., short: EFI is an American company and one of the leading manufacturers of proofing systems worldwide: EFI Colorproof XF, since 2013: Fiery XF. EFI is a software and hardware provider for Large Format Printing systems, RIPs and color management solutions such as proofing.
In early installations of Photoshop from the 1990s, numerous Euroscale or Euroscale profiles were installed, which still haunt some software today. In the UK in particular, the profiles still appear to be in widespread use.
However, their use is no longer recommended.
The IHK examination board for media designers – what exactly do they do? Quite simply, they are the centrepiece of the examination process. But what does that mean in concrete terms? Let’s delve into their tasks and their importance for the training of media designers. Planning and organising First and foremost, the examination board takes care of the assessment of the examinations; the prior planning and organisation of the examinations is carried out purely by the IHK and the vocational school. The IHK sets the dates, ensures that all examination …
Fiery is a product range of the company EFI – Electronics for Imaging. While in the past the name Fiery was mainly present for controllers for printers, now proofing and production systems are marketed under the name Fiery.
Film lamination is a thin foil coating which helps to protect the product (e.g. a book) from dirt and traces of use.
Flexographic printing is a printing process that is mainly used in the packaging industry. It is an indirect gravure printing process.
Fluorescence is playing an increasingly important role in the printing industry, especially when it comes to special effects and security applications. By using fluorescent colours and materials, printed products can not only stand out visually, but also offer additional functions such as counterfeit protection. But what exactly is fluorescence and how is it used in the printing industry? What is fluorescence? Fluorescence is the property of certain substances to glow when exposed to UV light or other high-energy light sources. These substances absorb the light and emit it again in …
With frequency-modulated screening (non-periodic screening), the halftone dots are distributed pseudo-randomly. Different tonal values result from the varying number of dots of the same size on one surface.
