Digital Printing, Spot Colors and Expanded Gamut

[chevalier]

I've seen what has happened (and continues to happen) to the commercial litho market in the digital arena and my gut says paperboard packaging and labeling is next in line. Our brothers and sisters in the commercial litho market don't have to deal with spot colors much and current solutions are aimed at them. For us packages the problem arises of Spot Colors and/or Expanded Gamut to simulate them. I've researched this topic off and on for a while and there really isn't much data out there.

What realistic digital solutions (of any non-offset-litho or flexographic printing technology) are out there for expanded gamut to match/simulate non-metallic spot colors? What about metallic inks? What about actual spot inks? What about substrate issues? Are market forces pushing buyers and creatives away from spot colors? I think this is very important to the future of our subset of the industry. I'm sharing my thoughts below but what are yours?

I have an Epson Stylus Pro 9900 proofer with integrated Spectrophotometer and CGS-ORIS ColorTuner and Certified Proof where I can automatically read spot colors and get color data. The spot color matching results have been somewhat disappointing. Substrates are a second concern with the ink set. When I look at other inkjet machines without the expanded ink set of an Epson*900 series I see a huge problem. The Epson WT series and Roland VersaCAMM series offer some neat coating and metallic gains in this arena but seem to shortchange the color gamut to achieve it. What about larger scale technologies like the Fuji J press?

I've read about the HP Indigo and the capacity it has for extra channels but that seems to be an extremely neglected area. Does anyone have out thee have any actual experience with one using spot colors or attempting some kind of expanded gamut?

I read recently about the Xerox iGen4 EXP (14.33" x 26" sheet size) with the new "matte ink" but I can't find anything showing the actual color gamut. The in-line coating, binding, cutting and other finishing touches are also an awesome idea. I'm quite curious about multiple inline Epic anilox coaters with use of flexographic UV spot inks in them. Although this causes the need for expensive photopolymer plates (and support equipment). These plates and inks would also eliminate nearly all the gains of digital printing.

The MGI Meteor product line also looks very promising but 10pt stock limitation is pretty much a no-go for packaging.

If you are a vendor and have technology or solutions in this area I have an open ear and open eyes so please respond or PM me. I will be at GraphExpo specifically looking at these technologies.

There's a ton of paperboard packaging and labeling being done offset, flexo, and digitally (e.g. HP Indigo) using an extended process color inkset to replace spot colors. This work is being done in around the world but primarily in N. America and South East Asia.
For example, this old Planeta press in Wisconsin:



prints cereal boxes exclusively using a 6-color extended process ink set - hundreds of thousands of boxes a week.

When I did the marketing for one such solution I had a database of over a thousand product samples that our sales reps in the US could pick up at their local grocery shop to show prospective customers. I also stocked our booth with those customer samples at various trade shows. You should have visited my booth when I worked for that vendor. :-)
The reason why you can't find much data out there is because the printers that are doing this work do not want to talk about how they do what they do. Or the fact that they're doing it. It's too valuable to them to share.

There is only one printer that I know of that has gone public about their process and that is Fort Dearborn in Chicago. They've branded it "HiColour" and you can read a bit (but not the whole story) about what they do here: HiColour Printing - Fort Dearborn Company

The re-separating software for artwork seems fairly straight forward. We don't currently do this in-house but we do have customers who provide us files this way already. What I am curious about is when you try to do this work with non-offset or flexographic processes.

For L&P applications, HP Indigo offers a DFE (digital front end) for our presses that addresses this type of need. It's called the SmartStream Label & Packaging Server and is an OEM of EskoArtwork technology. The Color Kit option of this DFE, in conjunction with up to 7-color process in the press, allows for a very wide gamut and excellent spot color simulation. We have many customers that are successfully using this is their day-to-day production in prime label, shrink sleeve, packaging (both flexible and carton) and other speciality production; even in the demanding realm that is pharmaceutical!

If you're interested in learning more, HP will be showcasing this DFE at both Graph Expo and Pack Expo next month.

I will be sure to come by the HP booth at see this at GraphExpo.

Can you do iterations of your spot colors with CGS-Oris to lower the delta values? I know this is a feature that GMG has, but of course, your delta values will always be affected by your printer ink/paper combination.

Yes, I can and do for my special/custom ink matches where applicable.

When I got my new Epson I switched to ORIS from EFI ColorProof. I experimented with two ORIS stocks. One was the top-grade PSV stock that offered the best color matching I have seen yet on a proofer. I say that as someone who receives proofs from just about every vendor combination of RIP, proofer, and substrate out there.

The other stock is a lower-grade PSMC most closely matched the actual packaging SBS we print on. I have optimized everything as much as possible with the ORIS software to the PSMC stock and I am up against technological limitations. I found that overall the proofs were much more "realistic" with the stock that most closely matched the packaging material. We always provide ink matches on stock with hardcopy proofs. I should note that some spot colors are ~3dE and others are >20dE. It's just a case of limitations of gamut and paper.

I cannot say enough about how impressive the combination of the ORIS software, ORIS papers, and the Epson Stylus 9900 with integrated spectrophotometer is. However, my concern is less about proofing as this is tolerable with ink matches for the press and more about actual inkjet/electrostatic/etc. production printing which I foresee taking work away from the presses. I don't expect the Epson Stylus series to be a production machine but I do forsee the same technology packaged slightly differently eating market-share away from the presses in the near future.

Honestly, I was wondering when I would hear this given the news coming out of HP as of late. I get it that they want to focus on high-margin sectors and but to destroy/breakup the rest of the company to do it seems insane.

It reminds me of what Bob Lutz is yelling from the mountain top these days. Why a Rise in M.B.A.s Coincided with the Fall of American Industry - TIME

It wasn't much more than 6 years ago that a person from Kodak stated to me that the Epson would never be a contract proof. Shows how wrong you can be! I agree with you that the technology that drives the Epson/Inkjets will have an impact on large presses in the near future. I would expect retro fitting existing equipment may be an option, as well as new equipment designs(both of which I believe are around now.) It will be interesting(and then again, maybe not) to see how press operators wages will be affected by this new technology.
