New ChromaLife 100 Canon Printer Inkset 186
Mark Goldstein writes "Some exciting news today for everyone who loves the speed of Canon printers, but hates the fact that they don't have archival-quality inksets. PhotographyBLOG reader Phil Aynsley has sent me a translated version of a page from Canon Japan's website, which talks about a new ChromaLife 100 inkset using BCI-7 dye-inks, with promises of 30 years light-proofness under glass and 10 years antigas fading when used with Canon's "genuine photograph paper". Let's hope it leaves Japan and reaches the rest of the world soon. " The archival issue of printing is a big one for people thinking long term - this would definitely be cool.

Epson released the first Archival printer, the 2000p, in the summer of 2000. And it was rated for 200 years light-fastness. It was followed in 2002 by the very popular Epson 2200, which used a newer 7-color archival pigmented ink set, prints up to 13 x 19, uses roll paper, does borderless printing on many sizes, and prints at 2880 x 2880 dpi with a minimum 3 picoliter droplet. It produces more crisp pictures than any photographic process except the laser exposures of the Durst Lambda [digital-photo-lab.com].
They folowed that up in 2002 and 2003 with four large format archival printers of comparable print quality, the 4000, 7600, 9600, 10600, printing up to 44" wide by 100' long. All of these are rated at 100 years light-fastness.
Now, in 2004, they've released their third generation of archival printers, starting with the R-800, which is the first pigmented printer to produce true glossy prints without "bronzing," has a wider color gamut that any other consumer level printer of any photographic process, prints borderless sheets as well as CD's and DVD's, and prints at up to 5760 x 1440 with 1.5 picoliter droplets.

However, if it actually bothers you, you can fix it right now off any Epson print with an archival glossy protective spray, like PremierArt Print Shield or Lyson Print Guard Spray.
And no, the R800 does NOT have a wider color gammet then any other consumer level printer. Dye based inks are still superior in that regard.

Well, thanks for correcting my statistics on the Epson 2200, I did have some numbers wrong. But I'm surprised you'd be so nitpicky on that, and immediately follow it up contradicting me with complete misinformation about the R800. Since the R800 has 1.5 picoliter droplets and 5760 x 1440 resolution, they no longer have to use "light" colors to achieve smooth gradients. So they dropped light black, light magenta, and light cyan from the Ultrachrome inkset, and in place of those three, they added Red, Blue, and gloss optimizer. With the addition of red and blue inks, the R800 can cover almost the entire SRGB color space, plus a whole lot more green and blue. Epson claims [64.233.161.104] it prints a 19% larger gamut than HP's dye-based Photosmart 8450.

30 years is archival? Not. (Score:4, Insightful)
I have done a lot of research on this subject, and let me make one thing perfectly clear: There is no such thing as an archival inkjet ink. And there never will be, not unless the fundamental technology of inkjets changes radically.
Let me explain this to our presumably technically oriented slashdot audience. It requires some familiarity with the famous Milikan Oil Drop Experiment, which should be well known to anyone who studied physics. Perhaps some of you even performed the experiment in your high school physics class as I did. Fortunately we won't have to do any of the measurements, the analysis is strictly qualitative, not quantitative.
Milikan's experiment involves a vapor of oil drops suspended in an electric field between a cathode and an anode. The experiment had to use oil drops, because the surface of oil drops is ionized. If you do this with a neutral-pH substance, like distilled water, the droplets will not suspend in air inside the field. You would have to add significant amounts of salt or some other ionizing substance to the water to get it to interact with the electrostatic field.
And that's exactly how all inkjet systems work, from the fancy Iris to the lowliest piezoelectric inkjets. Small droplets of ink are propelled by electrostatic fields. The ink droplets must contain an ionizing agent or nothing will happen.
Unfortunately, ionization is the enemy of pigment. Ionization is the catalyst for oxidization, and causes fading. This is why some of the early Epson "archival" inks underperformed their rated lives. Testing was done by Wilhelm Research, in the clean air of Iowa, but when the inks were released, they were used in major metropolitan areas like Los Angeles, with high levels of ozone pollution. The ionized inks interacted with the ozone in the air, and the prints faded rapidly, sometimes in mere days or weeks, rather than the expected 80 years. The inkset was withdrawn, and obvious flaws in Wilhelm's accelerated testing methods were revealed.
If you look at any truly archival photographic process, the fundamental issue is neutralization of ionization. Adding salts is exactly the one thing you should NEVER do if you want to produce archival prints. But that is exactly what the inkjet printheads require for propelling the inks. Until a technology evolves that does not require electrostatic fields to propel ink droplets, inkjets cannot ever produce archival prints. It would contravene the laws of physics.
I won't even get into the chemical formulation of dyes, and let me make it clear, there are no inkjet "inks," they are all dyes. Inks have a binder, and dyes do not. Dyes cannot be deposited on a surface in sufficient quantities to provide a stable layer of pigment, they merely stain the surface of the substrate. An archival binder is just as essential to archivality as the composition of the pigments. And some pigments are particularly "fugitive," they fade rapidly while others do not, causing color shifts, especially in pale colors where a minor amount of oxidization and pigment loss causes major color shifts. There is no such thing as an archival CMYK dye set. Nobody has ever produced a full-color stable ink set, the magenta colors are particularly prone to fading. If you've ever seen a color poster hanging in a sunny shop window for years, you've seen the shift, the magenta fades away, leaving a sickly bluish-green image.
Well enough of that. Just realize that whenever "archival" is thrown around in the inkjet field, it's being used as a selling point. Every single person who makes an assertion that their ink is archival has a financial incentive to lie to you. Photographers and art curators have specific criterion for archival properties, and if you go to them and tell them you have a new dye that is archival, and it lasts 30 years without fading, they'll laugh in your face.

Do you have any references for this idea that all inkjet printers use ionized ink? It's true that the IRIS (now IXIA) printers use continuous-flow inkjet printing, where the ink is ionized and the droplets are "steered" by running them past charging plates and deflection plates. But most inkjets use thermal printing, where the ink is rapidly heated in the print head to make a bubble, which pressurizes the ink and squirts it out the nozzle. It is only aimed based on careful positioning of the print head. Epson, and some high-end professional printers like Roland, use piezoelectric printing. The piezoelectric effect is where a mechanical stress occurs in a material due to an electrical charge. A small piezoelectric diagram forces the ink out through a narrow (10 micron) orifice. Again, dot-placement is controlled by careful print-head placement, not by electric plates guiding ionized ink.
In fact, while Epson and HP's ink formulations are not known, there are many third-party ink sellers who do list their formulations, and they tend to be rather clear about the fact that they de-ionize [cjenkinscompany.com] the [transload.net] carrier [inkcartridgesworld.com] (water) before making the inks. And they don't add anything ionized. Yet, these non-ionized inks work with these printers. How is that? Fuji also mentions [finepix.de] that only a few expensive large-format printers use ionized ink.
Even if the inks were ionized, it is entirely unclear that oxidation would break down the large color particles in pigment based inks like Ultrachrome inks. Your arguments fail to address this. Pigmented inks are what were used in classical oil paintings, many of which have been displayed without glass since the renaisance, probably without significant fading. During this time, they've been heavily oxidized. You do not present any case that adding an ionizing agent to the ink would accellerate the breakdown of the pigments to make the inks significantly unstable. Do you have any research, or math, or arguments as to what makes you think that the addition of any ionizing agent would break down any conceivable pigment too quickly to make it stable?

Dyes cannot be deposited on a surface in sufficient quantities to provide a stable layer of pigment, they merely stain the surface of the substrate."
Yes, that's why, at least with dye-based inkjet inks, the paper is critically important to the life of the prints. The paper is the binder. There are two main types of inkjet photopaper coatings. Microporous coated papers provide the least protection against oxidation. Still, good microporous papers, like the microcermaic coatings invented by Asahi Glass, allow large amounts of ink to be deposited with quick drying and without smudging, and the more ink, the more it can oxidize without changing. They use tiny ceramic (alumnia sol) particles in a silca gel, which rapidly sequesters the ink. Viewed under a microscope, this paper looks like jagged mountains. This is how they gather enough ink to "provide a stable layer of pigment." That's why these papers are usually used with more stable inks, they don't protect the ink much, but they take a whole lot of it into the paper.
Swellable Polymer papers use a nonporous coating of organic polymers that are water-receptive and SWELL TO SURROUND THE INK after it hits the paper. The majority of the ink is completely protected from direct air exposure. How do the inks oxidize, then?
Kodak has managed to combine these two approaches in their latest Ultima Picture Paper [photographyblog.com], which both takes a heavy coating of ink and en

Inkjet printing is directly related to digital originals... noone does an inkjet print from film.. AFAIK and why would they?
Digital originals can be stored, backed up and copied to unlimited numbers of archival repositories; backup floppies, backup zip, backup CD backup DVD. backup Hard Drive, backup Flash... and through the miracle of lossless duplication (whether the original is a lossless of the raw data or not).. you can keep a backup copy of the digital original for as long as you
10-30 years is LONG TERM and ARCHIVAL? (Score:3, Insightful)
Thirty years is "archival?" The crappiest stuff in the world will last thirty years. Canon is bragging about thirty years?
And that's probably an exaggeration. There are probably a lot of asterisks about humidity, and what kind of glass it is stored under. (A lot of those CD-R's that manufacturers said were going to last a century are starting to fail in less than ten years).
Light purple spirit duplicator documents will last thirty years. Even if they're a lighter purple than the day they were printed.
Books printed on World War II paper have lasted more than thirty years.
Any old black-and-white photo will last a century, easy. After a hundred years or so it may not have a full rich Ansel Adams tone scale, but you can see that your baby has Great-Grandma's dimple just fine. And that's the one that was sitting in that leather frame on Grandpa's office desk for all those decades...
So, these inkjet photos. Sure, you can always print them out again... except that our supposedly permanent digital media are, of course, only permanent if we are vigilant conservators ready to recopy everything over to a new format every decade or so as technology advances.
Two hundred years from now historians are going to know more about the 1800s than they do about the 2000's.
inkjets not archival (Score:3)
Personally, I bought my wedding negatives from the photographer and did all the prints using traditional B&W silver halide paper in my basement darkroom. Fiber-based paper toned in Selenium will last 200 years or more. Heck I even printed the color negatives on B&W paper and they look great.
I have family pictures that are 80 years old and look fantastic. The sad part is that Joe Sixpack's treasured family pictures, created on inkjets or even shoddy photo labs, will not be viewable 80 years from now.
