    What is the best printing Software – Qimage or ImagePrint by Colorbyte
    on: November 11, 2019 at 12:19 pm

    I am buying a new 24” printer by the end of November, either a Canon P2100 or an HP Z9+, have been using LightRoom Classic on my old Epson Stylus Pro 4900, and really am looking forward to finding a printing software that will help me get the best print possible on a variety of photo papers.

    ImagePrint and QImage do different things.

    QImage will scale and composite images for printing, using scaling algorithms that are varied and sophisticated. After that, it sends the image to the manufacturer’s printer driver, which does the conversion to printer primaries and the halftoning.

    ImagePrint uses its own proprietary halftoning algorithm. The ImagePrint halftoning has an advantage over the algorithms used by Epson and Canon (dunno about hp) in that it does not require scaling of the contone image to an even multiple of the printer marking engine resolution (usually the contone resolution is 360 ppi for Epson, and 300 ppi for Canon). ImagePrint will directly halftone from a contone image at any resolution, which is theoretically (and, most folk say, practically) superior.

    I haven’t followed ImagePrint recently — based on the number of people I know who are still using it, it doesn’t seem to be as popular as it once was — but the color management used to be less flexible than using the QImage -> printer driver chain.

    There is a considerable difference in price that varies with the printer used.

    Another approach is to use a program like Topaz GigaPixel AI for scaling and print from Lightroom.

    . Yea, you may calibrate your laptop screen, fix your brightness and maybe you can get a pretty good match, but for long term use, no, just use an external monitor, MUCH BETTER! (I use Eizo:P)

    I second this. Laptop screens have a lot of color variation across the screen, and tend to have color that changes with viewing angle.

    Jim,

    I have had conversations with Epson on this and other topics. They tout that clogging issues have been addressed. As you know clogging issues have been one of the issues that haven’t helped Epson over the year. My P800 very seldom has issues. One of the most reliable printers I have ever owned. Time will tell but I believe Epson is trying to clean up their reputation.

    My P800 has been fairly clog-free, too, but my sense is that the pro printers, including the 5000, are built for people who print every day.

    I find this an upgrade over the current Nikon 80-400, especially at the wide end:

    However, I find myself reaching for the Nikon 180-400/4 in situations where its heft is manageable. That is maybe the best zoom I’ve owned, even counting the Fuji 32-64/4. Not cheap, though.

    I’ve owned the 9000, 9500, and still own the 9800. The thing I like best about the 9800 is that it doesn’t clog much in intermittent service. I had a 3800 that was the same way. But I also had a 4900 that clogged unless you ran it every other day. I’ve got a friend with a 9900 who says the same thing happens to him. That’s why I bought the P800 instead of the 5000.

    I could be a customer for the new printer if its clogging properties are like the 9800. Is there any way to tell? I have an exhibition that needs printing by the end of December.
