Do JPEGs Reduce Print Quality? Updated!
HTML-код
- Опубликовано: 24 май 2022
- Concerned that printing photos from JPEGs will reduce the quality of your prints? In many cases, printing from a JPEG or an 8-bit TIF file will not cause quality issues but in certain situations, they can cause color banding. In this video, I show you how to find out if banding will be an issue and give recommendations for when printing from an 8-bit file will be safe. Of course, if you have the option, the safest bet is to print from 16-bit files.

After all your work, prints and time a thumbs up seems pretty minimal! Thanks for all your efforts!
Interesting discussion. A subject that often comes up with who appreciates printing at a high grade level. After years I have broken it down into 2 export modes. TIFF 16BIT proPhoto for printing. Jpeg srgb for digital media.
Thanks a lot for the time and effort into the subject
Hi Matt, I saw your comment. I noticed that Lightroom now does 32 bit tiff files which I printed one the other day and it looked amazing. I don't exactly know all of the tech data that goes into printing. I'm not a scientist feel like you need to be a scientist, understand it, but they look amazing.
We (a batch of bleeding edge folks) went through this maybe 35 years ago with dpi, spi, supercells, imagesetter resolutions of 3600 dpi versus lasers at 300 dpi...and if the printing equipment can handle it, the bit depth and dpi can never be too high. Low res and eight bit, eventually will show up.
I always print from my 16bit Tiffs
Thanks for sharing this, Sean.
Great, useful comparison prints. On the 16 bit and 8 bit forest pictures, while the color gamut was comparable, there appeared to be a loss of detail when going from 16 bit to 8 bit. Thanks for taking the time and effort to clarify the issue of the possibility of seeing banding when printing JPEG images.
Thanks for the tip :)
Tiff all the way for prints. If you zoom in on jpg vs tiff you will definitely see the difference. For me, shoot Raw, edit and export as Tiff. The print people sometimes say they just want a jpg but I insist on Tiffs. I come from a design background and saw the difference in print quality right away. Anyhow thanks for the excellent explanation..
Very helpful information.
Glad it was helpful!
Thanks for the vid. What printer/ printers do you use at home. Thanks for any replies.
My current printer is the Canon Pro-1000

OK, saving a Jpeg file in the Prophoto color space?? I always thought an 8 bit Jpeg file had to be in the srgb color space. I'm missing something. How can an 8 bit file format store such a wide color space? And why have I never heard of this in any discussions about color spaces or file formats? Are you a wizard? 🧙♂️
Hi Sean, I bought your editing for print video and was just wondering if changing the 300dpi would help with this? BayPhoto requires 8 bit and their new Epic prints are at 610dpi. One of their pages says they take ProPhoto and another says only Adobe 1998 or srgb. Kinda confusing. One course for printing I tried recommended lowering the dpi if you were printing big but it seems that’s not really the case?
This is a bit depth problem, so it would not affected by print resolution as far as I know. I agree that Bay Photo info is confusing. Lowering ppi for larger prints is old methodology from back before image upsizing software was as good as it is now.
Hi Sean,
I have an image of a wall that I have captured through my nikon d800. I want to print this image in poster size i.e 24inch X36inch and resolution would be around 300dpi. Any suggestions on how I should prepare/enlarge this image in Photoshop
Hi Chirag. In Photoshop: 1. duplicate and flatten your image. 2. Go to Image>Image Size. 3. In the Image Size window, check the Resample box and select Automatic from the menu. 4. Enter 300 for the ppi. 5. Enter 24 and 36 for height and width. 6. Click OK and your image will be sized as you wanted it.
Hey Sean, Interesting indeed as I have been doing some printing at home and sending out to MagCloud PDF's for magazine style printing. What this has to do with your printing might raise another wrinkle or two. Essentially, my invisible problem was using Affinity Software, which produced PDFs that were unexpectedly massive. Research informed me that this was not expected, and I found some colorspace conversion settings that had to be tweeked. I was confused because these were fully edited images, exported to JPEGs and imported to the publisher then exported to PDF. Every step from the JPEG export on was sRGB. ? - ????? the heck?
So, I broke down after 20 years and have gone full CC suite. Relearning curve, and I have to get back to Ps and TK... The result of InDesign exports was a PDF only 10% the size of the Affinity created PDF. Image Quality for this type of print cannot be distinguished. So, why would these programs in various stages generate desperately different file sizes? Was it all colorspace info? And then you said something that got me thinking. If you start with profoto or adobe colorspace and convert to SRGB well, what did you expect? I think the input colorspace, the program used in the conversion, and to some final export colorspace and bit depth are all INTER-related. I've seen this with JPEG SOOC vs exported JPEGs, no banding in camera, banding after conversion. I think it's all like pulling a piece of silk rope through a backyard clothesline pully --- like re-compressing JPEGS but BIDirectionally .... Dennis
Wow. Not sure why Afinity would generate such large PDFs. That’s outside my wheelhouse. Hard to know what’s going on behind the curtain sometimes.
I have done lots of comparisons interestingly if I print a black and white image or one that's very moody, virtually no difference at all, but I also shoot some landscapes with sunset sometimes two, and I did notice with orange and red colours that the tiff file definitely produced a better image I'm going to stick with tiff because I just feel logically that it has more data in the file. It's a bigger file so what is in that big a file well I'm not an expert on that but I'm just going with the logic that because the file is bigger, there is more data in that file, hence You get a better image in my experience. Probably about 80% of tiff files produce better images
If I ever make a print for you, I'll keep this in mind. Otherwise...
Sorry, I simply do not understand what you are trying to do. FYI : no monitor today can display a ProphotoRBG, only a few can display an AdobeRGB and then again many can display only a 90-95% of the full AdobeRGB color space. Therefore what you see on your monitor screen is ??? A color space that has been converted / modified by LR or PS in a way that, of course, it showing problems… You have similar issues when printing. No printer is able to print ProphotoRGB, and only a a few brand new printers can support a full AdobeRGB…. And then again CMYK most often used or printers is far less than all color spaces that you use on a monitor, either sRGB or AdobeRGB.
