An LED is a ‘light-emitting diode’ and in the graphics industry stands for the new ‘LED’ light, which has replaced older light sources such as neon tubes and tungsten lamps. Neon tubes are mainly known from the D50 or D65 standard light range. Today, LED light sources are predominantly used for standardised light in particular, as they can be spectrally adapted better and often emit a more harmonious light spectrum than neon light.
In modern standardised lighting, it is possible not only to set up standardised light for one type of light, such as D50, but also to simulate D50, D65, incandescent light and much more using several spectrally different LED lines by dimming and mixing the spectra differently in one lamp. In addition, the LED luminaires can often be dimmed, which was not possible with neon tubes.
What the industry is still waiting for are cost-effective standardised LED retrofit solutions, but these are unlikely to be long in coming. As the big players such as JUST Normlicht and GTI have dominated the market up to now, only expensive retrofits of the entire lighting unit have been offered instead of removing the old neon tubes and replacing them with new LED tubes in the same housing. At JUST, for example, replacing a small standard lighting unit with four tubes costs several thousand euros, as a completely new unit is used here and the old one has to be disposed of. Today, specialised smaller companies such as Lacuna Solutions can also offer modern and innovative, controllable standard light luminaires for new standard lighting solutions.
Today, however, LED light sources with a colour rendering index of over 98 are also available on the market, so it seems to be only a matter of time before LED retrofit solutions for D50 and D65 standard light will also be available for the slim replacement of old standard light tubes while retaining the reflectors. If the European and American suppliers do not present any solutions here, then the Chinese LED construction experts will probably take on the market and enter the market with LED retrofit tubes for standardised lighting in the near future. In any case, LED technology is already sufficiently advanced.
In the current issue of Fogra News “Fogra Aktuell” Proof GmbH is involved in two places. Firstly, a summary of the Fogra report on our first FOGRA55 certification for seven-colour printing with extended colour space in CMYKOGV appeared. You can also find more information on our FOGRA55 certification on the Fogra website: https://fogra.org/en/press-releases/fogracert-erste-cpc-zertifizierung-fuer-fogra55-cmykogv-330 and on proofing.de: And secondly, there was a report on the completion of the research project for textile digital printing, FOGRA58, in which we were allowed to investigate and test the proof capability of the new textile … read more
In 2021 proof.de was again Fogra certified including Fogra “Spot cert” certification, i.e. for the display of spot colours such as PANTONE C and U.
After Eddy Hagen pointed out in this posts, that there were some major colour deviations between the brand new PANTONE Solid Coated Guide 2023 and the previous version especially for the PANTONE 2635 C, I was curious to lookup the same colours in the new PANTONE Color Bridge Coated Guide of 2023 and compare the colours with the previous version. I measured a dE00 of 8,15 between the two colours that Eddy mentioned, which is really far apart from how accurate PANTONE colours should match between the different PANTONE guides. … read more
Shortly after Adobe’s announcement to remove PANTONE colours from their products, PANTONE removed the popular PANTONE Find a Color from their website
From now on you can order proofs for metal decor printing on white sheet metal at proof.de: The ICC profile for Fogra60 is Metal-Printing_MPC1_FOGRA60.icc
This year we once again created proofs for Fogra certification and sent them to Munich-Aschheim for testing. With these proof prints, which we print according to three different proof standards and on three different papers, we point out that we not only deliver excellent proof quality through internal quality controls and checks, but that the quality of our proofs is also measured and confirmed by external experts. We have now had test prints certified by Fogra for the 12th time. We have also been “Spot-cert” certified for the display of … read more
A new generation of colour measuring devices is entering the market: in contrast to the classic measuring devices, which are available as a fully encapsulated system either as a colourimeter or as a spectrophotometer, and then supply the data to a computer via an interface or app or display it directly, the new generation of colour measuring devices consist only of lighting and software, with the optics of a modern iPhone from Apple being used as the sensor. Until now, there have been two categories of measuring devices on the … read more
Peter Jäger is an expert in colour management that reliably works across the boundaries of printers and monitors, web and print – essentially: cross-media.
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
