Ask Slashdot: Best Option For Printing Digital Photos?

rrossman2 writes "With the birth of our son (who is now just over two), we have snapped and accumulated a ton of pictures — on Panoramio, Picasa, Facebook, etc. What is the best option for bulk printing the photos to a physical format? We all know how fast technology advances, as well as how fast sites come and go; I want a way to have these pictures for my son when he is older... just like my grandfather has photos of himself from World War II, my parents have photos of me when I was little, etc. Are there any affordable services that you can upload the photos to that print and deliver long-lasting pictures? How well do today's photo ink jets last, and what's the best type of paper? I do have a cheaper Samsung color laser printer, but color lasers don't make the most color-rich prints, and using normal photo paper you can find in big box stores doesn't work out too well, as the laser toner seems to peel off on the rollers and gum things up. (Is there a good long lasting paper that seems to work well with laser printers?) I can see what's going to happen in the future: all of the digital photos people take now are going to either end up on a website that won't be around in 20+ years, or get stuck on disks or flash memory that won't last, or for which interfacing with the media will become difficult or impossible."

      2nd this. Costco actually has relatively decent color quality (compared to other 1-hour photomats) and it will be much much cheaper than printing yourself. Just take in your burned disc or thumbdrive. Be careful about scaling though if you've played at all with cropping your photos.

      If you want to splurge, see if there's a local professional film lab around (like A&I in Los Angeles). Thats where you'll find the best digital printing available. But, if your photos aren't professional quality in composition, color adjustment, etc, you probably won't perceive the difference.

      The photos printed from an actual photolab from your digital images are better quality, cheaper, and since they're not on ink-jet ink they don't tend to fade as much.

      I concluded several years ago you can't really efficiently buy the ink, paper, and printer to do this on your own. It's just not cost effective. In the long run (and possibly the short run) it's more work and more cost for less overall quality.

      Another vote for Costco.

      Run up the numbers yourself per-print for a typical inkjet - look at the manufacturer's own figures for estimated cartridge life at 95% coverage, divide that by the cost for a full brace of cartridges and tack on the price for a sheet of photo quality paper.

      IME you'll find it usually comes out about the same, maybe slightly dearer than using a major photo processor. But that only tells you part of the story.

      It costs about the same provided you have a 0% waste rate and you ignore the cost of the printer and any associated items.

      That means no paper jams, no wastage from trial-and-error figuring out optimum settings, no discovering the hard way that colour temperature on screen and on paper are two different things, no ink wasted because you didn't use the printer for a week and it now needs to run a cleaning cycle.

      In the real world, you'll probably find this adds 20-30% to your costs. Obviously with practise you can reduce this, but even if you get it down to zero (never going to happen), it's still going to be at a photo finish between you and Costco.

Trying to bring them back to proper color was a nightmare, not made easier by my lack of skill with Gimp. But some of the photos from 50 years ago looked like they might have been printed last week. The colors were still vivid. I have no idea what process was used on any of these prints, but it was very clear the process makes a world of difference.

    Whatever you decide to do with the prints, I strongly recommend getting some archival quality sleeves to individually store them. Even if you then put them in an album, put them first in archival sleeves. The prints will be protected and will never again be exposed to fingerprints. They won't get scratched. They'll be reasonably well protected against UV fading. Then lock it all in a light-proof vault. Light is the mortal enemy of photo prints and even good quality UV protection will still allow some small amount of UV to penetrate. Keep the prints in a tightly sealed box and you should have few problems with fading.

    Honestly, though, if you really care about preserving these for posterity, just keep them digital and use some kind of offsite backup. Know going in that you'll probably have to move them around several times over the years as companies come and go and technology changes.

    You have to be very careful with dye-sub work. First off, there's two kinds. One is "inkjet" printing that uses gaseous colorants to create the image, and the other is simply printing onto a transfer medium and then using a heat press to imprint the image.

    The first is commonly used for things like name badges (we actually have some printers here that do it) or photos, and yes, dental and medical images, but the process is often limited in available classic substrates (canvas, luster photo paper, etc). That little Kodak kiosk thing that may be at your local Wal-Mart can claim it's this kind of "dye-sub", so they're not all created equally. The second type is useful for printing onto dimensional objects, or objects that cannot be fed through an inkjet, but you lose saturation during the transfer process. A shop using "dye-sublimation" can claim either of these, and not be very good at it in any case.

    As for as longevity goes; this is ALWAYS a function of the colorant and substrate you use, aggravated by the conditions you store the output in, and has little to do with the original process of getting the color to the substrate (solvent, UV, and Latex applications excluded; by their very natures these inks attach to the substrate more aggressively).

    Generally speaking, dye inks (colored solutions) will fade fastest (magenta first, in most cases, and that sucks because dye inks are typically the most vibrant), pigment inks (solutions with wee little colored flakes in them) will fade more slowly, solvent inks (more aggressive pigment inks) more slowly still, with latex and UV inks typically tied for the slowest, depending on substrate. All substrates must be acid-free, too, or you're hosed, as the substrate itself will start to yellow, fade, and break down as UV accelerates the process. There are also ways to protect any existing or brand new print regardless of the ink used; check out the way the Library of Congress does frames and archives their prints and paper items for a good idea on how it's done: http://www.loc.gov/preservation/care/mat.html / http://www.loc.gov/preservation/care/paper.html respectively. It's a pain in the ass, but following true standards always is.

    Basically, take what a manufacturer of a printer, paper, or ink says about longevity with a grain of salt; the requirements for Epson, Kodak et. al. to say "will last 75 years!!" are lax to the point of ridiculous. I'm not blasting them; especially Epson, as I have 4 of their printers and they truly ARE absolutely amazing. It's just that there IS no standard for testing print permanence, so anybody can claim anything: "If you leave your prints in a lightless vacuum in extreme deep space, it'll last for a kajillion years!!!" Well, duh.

    For instance, this is Epson defending their testing practices against Kodak's, while admitting that their own are not very realistic (and it's an amusing public gripe, to boot): ftp://ftp.epson.com/webfiles/whitepprsum.pdf. A shamelessly cherry-picked quote:

    "Currently there is no ISO print permanence standard for digitally printed photographs, and there is no prediction as to when, or even if an ISO standard will be established."
