The GL Opticam 3.0 4K TEC is the first fully adapted system for street lighting measurements according to the EN 13201:2016 standard. In seconds, the system provides all measurement data necessary to calculate the standard compliance for luminance distribution of selected street and area lighting. All award-winning products were presented as part of a special show.

At this year's Light + Building, GL Optic focused on current and complex topics, such as the change in eco-design guidelines and their requirements for the industry. At its booth, GL Optic presented its measurement systems, which can be used to determine important parameters that are essential for compliance with the new directives. With the GL PHOTOMETER 3.0 LS + FLICKER, a laboratory-class photometer, fast photometric measurements of all relevant parameters are possible. Also the GL SPECTIS 1.0 Touch + Flicker, a portable spectroradiometer, allows measurements such as light intensity, illuminance, CRI, PstLM, SVM data and others. GL Optic presented individual sets of measuring instruments, software and integrating spheres for specific application requirements. 

Light + Building was a great success for GL Optic. We would like to thank all visitors for the numerous exciting conversations at our booth and look forward to seeing you again at the upcoming trade shows and events of JUST Normlicht and GL Optic.

JUST Normlicht presented a sample of its Digital Light Systems (DLS) based on patented LED technology. All of the systems exceed the ISO 3664 and ISO 3668 viewing standards. The DLS colorCommunicator, a desktop viewing system idea for 2-D comparisons was shown, as well as the DLS Color Viewing Light v7, designed for both 2 and 3-D objects. Also included were the larger format DLS proofTop Multi and JUST’s fully programmable light source, the DLS Color Viewing Light v2.

For label producers, buyers, and users interested in multiple light sources, ideal for checking metamerism, the newer DLS Color Viewing Light v8 was shown. With a very attractive price/performance, this is the only viewing system available that supports the new CIE LED illuminants, as well as traditional fluorescent sources. Additionally, attendees really appreciated the “UV-only” modes that all DLS models support, allowing rapid detection of “invisible” UV area such as watermarks and security features, as well as simple detection of adhesives, fluorescent inks and optical brighteners in inks or substrates.

JUST’s presentation was well-received, leaving us to label the event a great success with existing and new customers sticking to the JUST name for quality, innovation and reliability.

Visitors were also informed about the differences between general LED lighting and the patented JUST LED approach (Digital Light System - DLS) which exceeds the requirements of the ISO viewing standards.

JUST had several DLS color assessment booths on display including our new DLS Color Viewing Light v8. The DLS CVL v8 features the same high-quality illumination and long operating life customers have come to expect with JUST DLS v7 but with the added flexibility of additional light sources. v8 models come standard with CIE D50 & D65, UV-A and two customer selectable illuminants making it the ideal solution for both matching customer environments and metamerism detection.

We would like to thank all attendees and exhibitors who visited our booth. We look forward to seeing you again at IWF 2024.

Until recently, fluorescent tubes were the closest match available to the D50 daylight spectrum. However, when dimmed for soft proofing, this technology produces a warm color shift. Their mercury content also produces sharp spikes in the light spectrum. Additionally, phosphor aging inside fluorescent tubes causes color coordinate shifts over time, leading to inconsistent color assessments. All fluorescent tubes require replacing after about 2,500 operating hours to remain within the ISO specification. In the case of Prinovis, all sites of the company had to replace the tubes simultaneously, as they needed approximately the same viewing conditions at all company sites.

Prinovis’ long term goal of exactly programmable and replicable color matching conditions became possible with their implementation of JUST LED technology, resolving all issues with fluorescent tubes, while adding significant benefits. For the first time, everyone at Prinovis, irrespective of the company site, can see the same color.

Further benefits of the JUST LED technology include:

• Near perfect simulation of D50, the closest of any commercially available fixture and substantially exceeding the ISO 3664:2009 specification
•  Continuous dimming without color shifts, idea for soft proofing
• Switchable illuminants between D50 (5000 K) and D65 (6500 K) and switchable UV content, allowing identification of optical brightening agents (OBAs)
• Expected lifetime of 45,000 operating hours (approximately 20x fluorescent tubes)
• Precise inter-luminaire color conditions over time

Providing the closest conformance to the CIE D50 and D65 illuminants available today, the JUST LED moduLight – Dual Illuminant D50/D65 product family includes a host of unique features such as instant switching, UV inclusion/exclusion, and digital dimming for soft proofing. With a guaranteed 50,000 hour lamp lifetime, maintenance and annual tube changes are eliminated.

Many thanks to the PIA jury for getting this award which is really an honor to us.

The new JUST Normlicht LED proofStation 20 SP wins the EDP-Award in the category „Special Solution“. The LED-based colour viewing station for visual colour evaluation of proofs and prints doesn’t need fluorescent lamps anymore and annual relamping. The switchable light between D50 and D65 according to ISO 3664 and ISO 3668 is impressive to the jury. The jury praise the LED proofStation 20 SP as “Great solution not only for digital printers. It is flexible in terms of standardization aspects and light which will be more and more important as well for digital printing in all the different applications“.

We are grateful to the EDP jury for their esteem to our product development and company.

For those who were interested in the colour assessment of decors and edgebands, we presented our standardised light booths for visual colour matching. The colour viewing box with up to five illuminants (D50, D65, TL84, A, UV) provides standardised viewing conditions in terms of light quality and viewing environment.

We also introduced our new LED-based colour matching luminaire – JUST LED moduLight (Pat. No. US 8,592,748 B2). Visitors were able to switch between the standard illuminant D50 for visual colour assessment according to ISO 3664 and D65 for colour matching to ISO 3668 as well as turn on/off UV radiation by a push of a button to detect substrates with OBA (optical brightening agents).

We would like to thank all visitors for the numerous discussions at our booth about standardised lighting and look forward to a reunion at interzum 2019.

Experts in quality assurance, R&D, retailers and marketers alike, appreciated the wide range of solutions configurable to any viewing environment. While portable viewers appealed to mobile workers, the revised Color Control Center multiLight, a complete “visual assessment room-in-a -box“ was a real eye-catcher, allowing controlled assessments of large coloured plastic substrates to industrial standards as ISO 3668, DIN 6173-2 and VDA part 8B/8C.

Many visitors were impressed with how readily metameric coloured substrates could be identified while switching among different illuminants of the Color Control Center (D50, D65 and A). Metameric colours, ones that appear colour-balanced with one illuminant but different with an other illuminant, are particularly problematic in the plastics and rubber industries.

Thank you to all visitors for the positive discussions at our booth. We look forward to seeing you again soon.

Our Americas division presented a full line of JUST products for the label market, including the first presentation of new JUST LED technology in the Americas. Launched at DRUPA this year, the new LED proofStation 20 (Pat. No. US 8,592,748 B2) was well received, as attendees noted its versatility with both D65 and D50 light sources, lifespan of 10,000 hour and ISO 3664:2009 compliance. They were surprise to learn all these capabilities are provided at nearly the same price as traditional fluorescent viewing lights.

We also demonstrated the new JUST LED lamp SL-T5 II 950 proGraphic with high CRI for generalized lighting in the pressroom and other production areas where light quality is important, showing solutions with performance significantly superior to inferior retrofit lamps are here today.

Also of great interest were JUST’s multiple light source solutions „Color Viewing Light“, allowing visualization of how products are used in the end-customer’s environment, as well as inspection of UV coatings and adhesives. More advanced customers appreciated the ease of measuring lighting conditions using the GL SPECTIS 1.0 Touch spectrometer, produced by our GL Optic division.

Many thanks to visitors and numerous discussions about standardised lighting.

In the form of FOGRA51 for coated papers with moderate fluorescence, and FOGRA52 for uncoated papers with high fluorescence, characterization data for offset printing are now available with corresponding ICC and Device-Link profiles. The definition of measuring condition M1 in ISO 13655:2009, the standard for spectral measurement and colourimetrical computations, created a further important prerequisite. With illuminant D50, measuring condition M1 is based on a higher UV component, this being necessary for measuring papers containing optical brighteners.

The updated ISO 3664:2009 is an important standard in connection with the practical implementation of ISO 12647-2:2013 for standardised printing with papers containing brighteners. The standard for visual colour matching is of essential importance in this context. The requirements of ISO 3664:2009 regarding a limited metamerism index in the UV range, and the closer adaptation of the UV component in the spectrum to daylight, have already been met by the JUST daylight 5000 proGraphic fluorescent lamps from JUST Normlicht since 2010. As a result, all JUST Normlicht devices comply with ISO 3664:2009, meaning that, in combination with an M1-compatible hand-held measuring instrument, what you now see really is what was actually measured beforehand. Consequently, there is no longer anything to stand in the way of standard-compliant colour matching in accordance with the new process standard.
