    It doesn’t get much cruder than nearest neighbor.

    "Crude" is a relative term.

    As I said, I think most "mum and dad" photographers will not be able to see any difference in print quality in their prints when viewed under their normal viewing conditions if the printer driver did the interpolation.

    Everyone is entitled to decide for themselves if the print quality of their prints is acceptable to them or not.

    My vision is good for an old man, but not great. 20/15 in one eye, and 20/20 in the other. With a sharp, detailed file, the difference between NN and say, bi-cubic is obvious to me just holding a baryta print in my hands. I see no reason why a "mum and dad" photographer (whatever that means) should have impaired vision, so let's pas on that. It is possible that unskilled photographers make not be able to make sharp, detailed files. Is that your assumption? The other possibility is that the "M&D" photographer can see the difference and doesn't care. I suppose that's possible, though I see no evidence in favor of that argument. Or maybe the "M&D" photographer is printing on canvas.

    But why not get it right from the get go, if you've gone to all the trouble of buying a printer, buying good paper, calibrating your monitor, making or choosing the right profile, etc? Checking the right box in Lr and entering the right number there takes very little effort compared to everything else about printing.

    We, and anyone else who wanted to chip in, could very easily go on about this for days and turn this into another mega-thread.

    The 2 choices for where to do the interpolation comes down to user preference depending on their needs and acceptable print quality threshold. As long as the user makes an informed decision and they are happy with the print quality, that is all that matters.

    To make one, they need to know that

    Of course. We already established that so I'm not sure why you repeating that.

    As I said though, at the end of the day it is up to the user to decide for themselves if the print quality of the print after the printer driver did the interpolation is good enough for them.

    What is crude for you and Jim might still be acceptable to some. It is their choice to make.

    Was the interpolation to the native printer resolution done by the printer driver or manually in the printing app or some other 3rd party app?

    Very often I can get away with 200PPI for the paper size and still make very acceptable prints.

    I can remember it took about 30 min to get the image ready for printing. i think it was the printer software that prepared the image.

    Re: Crude interpolation. I find that my Epson s/w and drivers do a decent job - good enough to frame and sell.

    I also have a 24" wide printer - I need to try it out on a decent picture. Trouble is, it's really hard justifying the paper and ink costs just for a test.

    Many times the "crude" driver interpolation is more than good enough for me as well, especially when ppi for the paper size is reasonably close to 360 ppi, the printer's native print resolution.

    It's when the ppi for the paper size is well below 200ppi that I would definitely use one of the modern AI driven upsizing apps to resize the image to 360ppi for the paper size.

    Hi Alan,
    whats the longevity of the epson dye ink printers. im looking at the et-8550 for cost effective printing .

    Don,

    I don't know. I've only had my Epson printer since Feb this year.

    But this page www.adorama.com/alc/faq-whats-the-difference-between-dye-based-and-pigment-ink/

    There is big difference in longevity between different storage conditions!

    That link doesn't work, at least on my phone. unless you copy/paste it into the browser.

    You can't copy/paste urls into a post here like you can on dpreview and expect them to work.

    You need to use the "link" icon in the post editor's toolbar to post url links in posts. The "link" icon creates the appropriate Markdown code for the link to work in posts.

    I usually check links I post. It works in my Firefox. It opens in a new tab. Maybe because it's pdf some settings in your browser can prevent.

    It seems I can copy/paste links in my posts but the "link" icon did not work properly.
    I had a small discussion about linking here: dprevived.com/t/problem-in-inserting-link/1964/#post-18478
    I don't know if something is changed later.
