Alwan Color Expertise, an enterprise in colour management and process control software announces version 7.6.0 of its leading colour management and ink-saving software Alwan ColorHub. This new version has been optimized for digital printing presses as it offers increased spot colour accuracy, ink savings, and PDF-VT processing speed.

Alwan’s PDF colour server Alwan ColorHub has been originally designed in 2001 to help conventional printers better predict and control the colour and cost of their production.

With more than 1,500 servers used daily to optimize millions of jobs, Alwan ColorHub is considered today as a leading software in its category. However, the fast increase of high-volume digital printing and our partnership with Konica Minolta for their flagship digital press AccurioJet KM-1 taught us that there is a strong need and room for improvement for digital presses as well.”

Alwan ColorHub Version 7 – and even more so with version 7.6.0 – addresses digital printing specifics and takes colour spot accuracy, ink savings, and production speed to unmatched levels,” says Elie Khoury – Alwan founder and president.

Spot colour accuracy thanks to hydra profiling technology

Matching spot colours on a digital press is a challenge as digital presses do not have spot ink units as conventional presses do.

Therefore, moving jobs containing spot colours from conventional to digital printing is often disappointing or not done at all.

With its patented hydra profiling spectral technology, Alwan ColorHub is able to create a profile of the production device, to predict its spot color reproduction capabilities, and use Hydra profile for the spot to device colour conversions.

Result is that 10%+ more spot colors are matched with ∆E00 2 compared to conventional CIELAB based profiles.

More ink savings thanks to minimum TAC and ink usage colour separation technology

Digital printers use digital ink, also called digital gold due to their price.

Maximum GCR (Left), ink savings: 32%; Minimum TAC and ink usage (Right), Ink savings: 50%

Moreover, these inks are device dependant and do not have the same colour or characteristics as conventional inks do.

Maximum GCR (Left) – Ink savings: 37%; Minimum TAC and ink usage (Right), Ink savings: 44%

For these reasons, conventional UCR/GCR black-generation-based colour separation is not optimal for digital inks.

Alwan’s unique Minimum TAC and Ink Usage (MTIU) technology uses Hydra profiles to optimize the colour separation for digital inks and digital devices.

Result is 10%+ more ink savings and colour accuracy compared to conventional GCR and CIELAB based colour separation.

Production speed thanks to multi-page, multi-thread processing technology

Some digital printing applications such as books and variable data require special processing strategies in order to use the full power of the used computer or server.

Alwan ColorHub 7+ versions use new multi-processor, multi-thread processing technology that optimizes PDF processing speed.

Result is a decrease of processing time by a factor of 2 to 10 depending on the computer and the job.

When we recently interviewed a representative sample of our users, we found out that most of them were able to move previous offset jobs containing spot colours to digital printing without any problem.

On the contrary, their feedback was that, because of decreasing print numbers and increasing colour expectations, they were more confident, and making more money now printing spot colours using their digital press with Alwan ColorHub,” says Elie Khoury – Alwan founder and president.

Alwan Color Expertise is a worldwide enterprise in colour management, process control, and standardization software.

Founded in 1997 by industry international expert Elie Khoury, Alwan develops, distributes, and supports innovative software solutions allowing actors from the graphic arts industry improve margins through standards and automation.

Designed with the end user’s expectations at heart, all these products are workflow independent and deliver cost-efficient and high-quality results.

The suite of software proposed by Alwan are compatible with all printing processes (offset, digital, flexography, gravure) and ink palettes (CMYK, spot, multicolor).

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
