CHROMiX News What the heck have we been up to?

Announcements Galore / PU Booth

We've been toiling away and put the pandemic lockdown to very good use including, at long last, this new issue of ColorNews.

We're very excited to announce that CHROMiX has a booth at Printing United in Las Vegas this year (two weeks from now, Oct 19-21, 2022). It's booth N1071, in the North hall, near the Kodak booth.

Plus, we will be demonstrating how well our software works with two great measuring instruments: Konica Minolta Myiro-9 (formerly FD-9) and the Barbieri LFPqb Textile edition

Stop by or make an appointment! Come by our fully staffed booth anytime Wednesday to Friday. Or if you prefer to make an appointment, reach out to Rick Hatmaker at hatmaker(at) or call at 206-985-6837 ext 1.

The following announcements all apply to what you'll see in the booth

Maxwell 22 - Monitoring color doesn't have to be difficult or expensive

Maxwell's web interface has been completely rebuilt and modernized and we're launching it at Printing United. We've had customers beta testing for over a year under super-secret NDA and now it's available immediately after the show.

The completely rebuilt web interface provides:

  • Interactive graphing
  • Ad-hock comparisons
  • Dynamic dashboards
  • Peer comparisons
  • Live data updates for all views
  • Jobs AND track reporting available for both workflow types
  • Integrated brand color reporting across all services
  • Integrated help and walk-throughs
  • PQX/PRX support for integration with other tools and workflows (by year end)
  • Direct integration with Curve4 and ColorThink4
Live demonstrations ongoing in our booth. The interactivity and clean design should really be seen.

We're hosting a webinar Nov 3, 2022 at 11:00am Pacific Time for those who missed the show or want more details. Sign up here

We're very excited to show the next big release of ColorThink. It's entering into beta testing after the show (really) and is expected to ship in the 1st quarter of next year (also, really). Many of the technologies we've developed for Curve and Maxwell have found their way into ColorThink and we know you're going to love them.

This long-anticipated update is a huge upgrade from version 3 and the features we're showing includes:

  • Many additions and improvements to the Grapher
    • New viewing spaces and modes
    • Image flow (must see)
    • Graph views
    • Gamut comparison subtraction
    • N-channel graphing improvements (huge!)
    • dE blobs
  • New Color Assets handler
  • Integrated instrument support
  • Color Worksheet
    • Color patch tuning
    • SCCA conversion
    • List joining and filtering

3D Holographic LED display giveaway at our booth

You might be thinking "Is that a real 3D LCD display?" Yes, it is.

You might be asking "Are they giving one of those away?" Yes, we are.

ColorThink4 will export a special 3D file that the Looking Glass Portrait display can show in full, glorious 3D splendor.

To mark this event we're giving away one of these displays to some lucky soul who drops by our booth and enters to win. We'll be showing ColorThink's graphs on this display in our booth, so come check it out.

CHROMiX Wins 2022 Barbieri Excellence Award

CHROMiX has been selected by Barbieri for it's Excellence Award!

"CHROMiX develops software for the digital printing market and spectral color data is a cornerstone for its software evaluations. We found there there is a deep understanding in how to connect and integrate spectral data and color measurement technology which allows customers to gather the highest accuracy."

The feeling is mutual. We love Barbieri devices and work hard to incorporate effective and seamless compatibility with our software.

Avoid compliance hell with PRX/PQX by Steve Upton

Color verification and compliance tools are gaining in popularity and print buyers are realizing their value. What's not to like? Buyers can put their newly-learned color and G7 ideas to work, ensuring their print procurement is consistent and pleasing to the eye.

Some buyers are taking their vendor's advice and requiring printers to use specific software tools or cloud services. This creates an untenable situation where printers have to buy, learn and use multiple tools in order to gain the customers' work they need. A vendor representative recently confided "We have printers who are required by customers to buy and use 4 or 5 different color compliance products in order to print their work. It's insane and unnecessary."

Don't torture your print providers by requiring proprietary tools' measurements for compliance testing.

What many don't realize is that color verification math is essentially open-source. The formulas, units, and tolerances are available to everyone and most tools use the same foundational tech. How they differ is in their approach to the problem, their workflows, and their levels of automation and reporting. (have I mentioned recently how awesome Maxwell and Curve are at such things?)

This means that the foundations exist for the many verification tools to share data easily. Thankfully, Idealliance and ISO have created standard file formats that allow this very exchange to occur: PRX and PQX. PRX (Print Requirement eXchange) and PQX (Print Quality eXchange) are standard XML file formats created by Idealliance to allow for the clear exchange of print requirements and the resulting print quality measurements.

PRX/PQX allows printers and buyers to choose the best tool for their needs

Brands and print buyers encode their requirements into print requirements files (PRX) and make these files available to job bidders and print providers. PRX files can handle color aim measurements, spot color values, preferred color metrics and tolerances. They also handle defect allowances and bar code verification requirements. Print providers, in turn, import the PRX files into their verification tools so they can confirm their output adheres to the buyer's needs. It allows for buyers to use software best for their perspective and for printers to do the same. One size does not fit all and it doesn't have to.

The measurements, barcode verifications and defect tracking are then exported into print quality files (PQX) and shared back to the buyers and brands. These files are imported into the buyers' tools and the circle is complete.

Like ICC profiles opened up the proprietary conversion systems of the 1980s and 90s, PQX/PRX open up color verification systems. The last 25 years of innovation and quality improvement have proven that the open exchange of color conversion and proofing tables makes workflows much more flexible and allows stakeholders at each point of the workflow to choose the tools that are best for them. Photo, design and prepress software support ICC profiles for the creation end of the workflow. Proofing, workflow and RIP software support the output end. ICC profiles tie it all together.

PRX/PQX allows stakeholders at each point of the print supply chain to be supported with the tools best for their needs and their customers' needs. Conformance checking is not supposed to be handcuffs on printers, but that's how it's evolving when print buyers specify proprietary systems which must be used to report color compliance measurements and results.

Dianne Kennedy, Editor of ISO 20616 (the PRX/PQX standard) from PQX Consulting said "The ISO standard, ISO 20616, that codifies the standardized exchange of print compliance data has been published, however adoption of PRX/PQX is far from assured. As with the adoption of G7, pressure from print buyers holds the key to widespread implementation and adoption."

Brands and print buyers: Choose software that works from your perspective and require it to support PRX/PQX exchange. Avoid requiring print providers to use specific tools that are often not appropriate for their situation and make their lives more difficult. The extra expense is passed back to you anyway, one way or another.

Printers: Choose software that works best for your needs - process control, quality assurance, and compliance verification and require it to support PRX/PQX exchange files. When buyers require proprietary systems be used, alert them to industry tools like PRX/PQX and urge their use in specifying their requirements. Send them a copy of this article if you think it will help. Direct them to Idealliance, an organization that is explicitly tasked with removing workflow barriers across the entire supply chain.

Visit our booth N1071 @ Printing United in October to get more information about how PQX/PRX makes the printer's and the print buyers' lives easier. We've announced this week our Maxwell 2022 upgrade which soon supports the import and export of both PQX and PRX files, easing the exchange of compliance information and the pressure on printers to use multiple products to get customer work.
