New ChromaLife 100 Canon Printer Inkset

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.

Once that desire is not there, your data is practically useless after 2 or 3 generations of memory devices have come along. And this hampers future generations from handling data that we archive now. Just look at the number of 8 inch floppy drives around, and think about how hard it is to re-copy the data on them. Now extrapolate that 100 years down the track. Plus once the mechanisms are no longer readily available, the desire to replicate them drops off.

    The main problem companies have had with switching to archival inksets is this: the most effective known way to make archival inks is to use pigment based, as opposed to dye-based, inks. But pigment ink particles tend to be much larger than the particles in dyes. (Dye particles are 1-4 nanometers, pigment particles are 50 to 200 nanometers.) This usually changes the viscosity of the ink solution, and the larger particles can more easily gum up the print heads.You can grind them up smaller, but the smaller they get, the less archival they become.

    One reason Epson is so far ahead in archival printing is that they're the only company using piezoelectric diaphragms in their print heads. Everyone else uses thermal print heads, which heat the ink in order to spray it out, which tends to gum up the print heads more easily anyway. In fact, every other brands' heads gum up so easily that they put disposable print heads on the print cartridge, where Epson printers come with permanent print heads. (Obviously, this allows them to make a killing on ink compared to the competition). This may be why Canon's only advertising a 30-year ink as opposed to Epson's 100-year Ultrachromes- they may have to grind up the pigments smaller to stop them from clogging in their thermal print heads.

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.

      I decided to learn about inkjet dyes and (pigment) inks immediately after reading sashuka's post. I felt it necessary after seeing him so vehemently deny the existence of pigment based ink. After fifteen minutes of light research, the following document revealed the existence of a milled pigment inkjet ink. EPSON's UltraChrome Ink Factsheet provides information in detail. Below are listed some of the clues to this ink's existence... clues which EPSON cleverly hid on their own website!

      It appears that EPSON has had a line of inks for (at least) a year now that are milled pigment inks in an acrylic suspension. Their method of delivery is inkjet technology.

      According to the literature, EPSON UltraChrome(tm) Inks are: "super penetrating pigment inks" that "are engineered to deliver incredible print quality and color brilliance rivaling that of dye based inks" and that have "a lightfastness rating of up to 82 years under glass on certain Epson media".

      They further go on to describe these inks as consisting of: "Evenly milled microencapsulated pigments."

      Since EPSON compares their ink to dye-based ink, and since dyes use pigments dissolved in solution, not "milled pigments in suspension", we can safely conclude that EPSON makes a non-dye based ink. This would seem to invalidate your proclamation that states, "there are no inkjet "inks," they are all dyes."

      Now, I don't want to seem harsh here, but I feel you need a little bit of a scolding. You see, I'm tired of amature hobbyists who also happen to be intelligent jumping on Slashdot and proclaiming their knowledge of the state of the universe without actually knowing what they are talking about. There is something which tempers the sharp cutting edge of intelligence and guides its proper use. It's called wisdom.

      One of the primary assumptions which wise people everywhere seem to know intrinsically is that no one knows everything about anything. So be careful when using words or phrases like never, impossible, no such thing, et cetera. I would also add that it compounds the problem when you make such proclamations in bold text. You might give off the impression that you are on a rant.

      It doesn't matter if Epson calls them "microencapsulated pigments," the particles still just lie there on the surface of the paper, so they're still dyes, technically speaking. You need a binder to encapsulate the whole layer of pigments, in order to lay down a sufficient amount of pigment so that when they start to oxidize, there's still enough unoxidized pigments to be stable.
      Watercolor pigments use gum arabic as a binder. Oil paints use linseed oil as a binder. House paints use latex as a binder. No binder means it's a dye or a stain.
      And yes, I do have professional qualifications in these matters, I have professional training in archival printing, I have consulted with the field's top art conservators on these issues, and have worked at museums with professional conservators.

      Remember what I said: if someone declares their inkjets are archival, they have a financial incentive to lie to you. Epson sells lots of inkjets by convincing people they produce archival prints. Since when did you rely on marketers for truthful technical advice?

      You don't understand physics yourself. The color of hair comes from light refracting inside the hair itself. It is like oil paint, which has a thick body of binder with particles of pigment in suspension. The surface of the oil paint hardens to prevent air from penetrating and oxidizing the pigments deep in the layer. In the same way, the outer protein shell of the hair protects the pigment within the hair. Also, hair is coated with oils, which keeps oxygen from penetrating and oxidizing the color. Just go ask a woman what happens to her hair dye when it gets frizzy and dry from washing it without a conditioner.

      And besides, black and brown pigments like those found in hair are generally not prone to fading, it's colors like magenta that are considered "fugitive pigments." You're comparing apples and oranges.

      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 the carrier (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 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?

      "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."

      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, which both takes a heavy coating of ink and en

    If you want an archival color print from either digital files or traditional negatives, go to a lab that uses Fuji Crystal Archive paper in the traditional RA-4 process. Your print will last a 100 years and doesn't have to be underneath glass. In fact I recommend this even if you store your digital pictures on a RAID-5 array backed by tape. There is something to be said about the permanence of a print versus the permanence of digital bits.

    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.
