Stora Enso relies on JUST LED Normlicht for its innovative softproof solution!

For some time now, the topic of soft proofing, i.e. color matching and approval of prints by means of a digital proof on a monitor, has been in trend. In general, collaboration, and the associated remote color matching, is also becoming more and more important, not least due to the Covid 19 pandemic.

To simplify workflows and processes even further in the future, Stora Enso has now moved its softproof service to the cloud and developed a softproof box. Integrated in this softproof solution are JUST LED luminaires, which provide the ideal framework conditions for softproofing. Only if the exact same proofing conditions are provided at all ends of the process, such a digital workflow can work smoothly and successfully.

The JUST LED moduLight 1-800 used here is calibrated in the JUST light laboratory and therefore offers 100% identical and constant proofing conditions with the light types CIE D50 and CIE D65, each with and without UV content.

November 2020 // New product

LED entry level solution
for medium format (3B)

The new CHALLENGE D65/D50 combines the popular, minimalist design of the Challenge 5000 with the outstanding quality of JUST LED technology.

With the light modes D65 and D50, which can be switched individually, this color inspection station complies with the ISO 3664 and ISO 3668 standards. In addition, the UV component can be switched on and off.

With the CHALLENGE D65/D50 a new LED upgrade system is added to our product range. We can now offer all owners of a Challenge 5000 ( built in 2010 or later) an upgrade of the existing station, where only the lamp is replaced, but the station itself can remain in place.

Prinovis partners with JUST for LED ISO-compliant viewing

Prinovis, a leading, European printing group, has upgraded its color control stations from fluorescent tubes to JUST LED technology. The stations now provide standardized lighting conditions precisely conforming to the ISO 3664:2009 standard with the D50 (5000 K) illuminant.

As a leader in the printing industry, Prinovis had previously switched from hard-copy to soft proofing, dramatically improving workflow efficiencies. However, they found fluorescent tubes impact color matching accuracy, particularly when dimmed for soft proofing, so they sought a better solution.

Find out more »

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

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 colored plastic substrates to industrial standards as ISO 3668, DIN 6173-2 and VDA part 8B/8C.

Many visitors were impressed with how readily metameric colored substrates could be identified while switching among different illuminants of the Color Control Center (D50, D65 and A). Metameric colors, ones that appear color-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.

JUST Normlicht at drupa 2016

Over 260,000 visitors from 188 countries converged in Düsseldorf Germany to see and learn about new products and developments in the printing industry. For JUST customers and visitors, visual color control and assessments to ISO 12647-2:2013 with LED lighting (Pat. No. US 8,592,748 B2) were paramount.

2016 May // Color Matching Solutions

"The Missing Link"
Print. Measure. See. To ISO 12647-2:2013

Following adoption of the new standard ISO 12647-2:2013 for a standardized offset printing process, the prerequisites for its practical implementation have now been fulfilled.

Find out more »

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 colorimetrical 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 standardized printing with papers containing brighteners. The standard for visual color 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 color matching in accordance with the new process standard.
