Photoshop 8-bit or 16-bit for print

8-bit vs. 16-bit TIFFs for printing Show Nov 14, 2017 Assuming a sharp and detailed image, and printing with Qimage, is there a noticeable difference in quality when viewed from 3-4 feet, 13"x19" print from an R3000 on baryta paper, semi-gloss surface? The print from the 16-bit TIFF is tack sharp, with small details clearly shown. Would the print from an 8-bit TIFF lose sharpness - again, at normal viewing distances? I know, try it for myself. But my printer is currently a bit sick, and I need some printing done ASAP, so I'm farming out printing to a friend who has the same hw/sw, and need to decide what bit-depth I will use in the files I prepare for him. For some strange reason, he doesn't want to spend time experimenting.

And would your friend print a smaller sheet that you prepare by making a crop? You could even put both on one sheet: convert an 8-bit to 16-bit (check that the added bits are 0s), then lay out a sheet with the same image crop twice, once a true 16-bit and once the "16-bit" created from 8-bit.

Until you experience it, you've only imagined it. Some posting here are imagining without any testing. Until someone actually fulfills your exact testing parameters (and image content will play a role), you'll mostly get guess, speculation and assumptions. And that's fine if that's what you're after. You know, try it for yourself. I've printed 16-bit and 8-bit per color documents (the later from the former) on a printer who's driver does support sending the high bit data through the driver (very few provide this). I saw NO difference. When I measured the differences doing the same with color patches, the measured differences were below visibility (differences well below a dE of 1).

Exactly. 8 good bits per color. High bit is for editing to get those 8 good bits per color. http://digitaldog.net/files/TheHighBitdepthDebate.pdf Re: 8-bit vs. 16-bit TIFFs for printing 1 16 bit tiffs are for manipulation, mostly to prevent banding. But once you're totally finished, saving and printing it as an 8 bit jpeg works just fine (at least I can't tell any difference).

Kind of depends if the opinions are based on fact and testing or just made up by the poster who hasn't tested anything, assumes and then posts as seen just here, to up their post numbers.
Actually test this, what a novel idea for some....
You're kidding right? You really need to think harder about that concept before posting again.... And clearly you have little understanding about the role of dither on such conversions or how and why to control it! Need more help?

If you behaved in real life the way you behave on forums, someone would have served you with a restraining order. (unknown member) • Forum Pro • Posts: 13,189 What is it you do for a living??????? In reply to Charles2 • Nov 15, 2017 2
You seem to know as little about restraining orders as you do about imaging. Correcting people's mistakes on a technical level isn't the reason for restraining orders. It's just too bad there are no restraining orders on producing posts here that are filled with errors as this is why, you so often get called out and corrected! Necessary digidogmatism (your term) once again: https://www.dpreview.com/forums/post/59019744 Real life for some here is posting data that's factual, can be backed up by other peers, not posts based on assumptions, speculations and misunderstandings of technical subjects such as color management, image encoding, exposure; all easily misunderstood by you in dozens upon dozens of posts here. Again, if you have an issue being corrected about technical subjects that are easily verifiable, don't post assumptions and misinformation and you will never need to be corrected again. Make my life and your reader's life so much easier. You went out of your way to trim out a silly concept and of course, have no desire to know why it's so silly!

Spreading misinformation doesn't get you a restraining order, but correcting it does? ROTFLMAO bmoag • Veteran Member • Posts: 3,281 Re: 8-bit vs. 16-bit TIFFs for printing I am looking at a pile of prints made on the same two canon printers from the same machine that boots into OSX and Windows 10 using the 16 bit option in OSX. In many instances I printed the same image on different halves of the paper. The files were raw processed at 16 bits in Prophoto. In my unscientific survey of asking non-photographers, who might have required libation to agree to the task, to look at the prints if they identified any differences at all they tended to prefer the Windows prints as in some instances the Window prints seem to render better detail (this from the exact same file). No one has ever commented on significant color differences. The prints were all looked at close up, hand held. So if there is any difference printing from OSX 16bit and windows 8 bit I attribute it to the difference in the drivers rather than anything having to do with bit depth and for the most part if the prints were not compared side by side each would seem fine for what it is. I also have another pile of prints made before and after converting the image to sRGB. I invite you to speculate on whether there are significant differences in the prints. You can find your own answer with minimal effort and experimentation in OSX or Windows.

There are other possibilities for non color differences on the OS; if the image data needs to be interpolated! https://www.digitalphotopro.com/technique/photography-workflow/the-right-resolution/ See Schewe's comments about the drivers and OS in terms of what we don't know about interpolation to make that print.
I have prints where the differences are visually significant: http://www.digitaldog.net/files/Gamut_Test_File_Flat.tif Convert to sRGB and make a print too. Ouch. Re: 8-bit vs. 16-bit TIFFs for printing
Your workflow will influence whether or not you see a difference between 8 and 16 bit printing. If the printing profile is being applied later in the process (perhaps by the printer driver) then there can be a visible difference between 8 and 16 bit. If you are printing from Photoshop, and Photoshop is handling this, then you not see a difference. While some might suggest you should always use PhotoShop's color management, not everyone has this option.

When does one see a difference in printing?
Got examples/proof? Note the text: perhaps! 😖
Color management is the least thing to make a visual difference! Got any idea the dE of several CMMs?

If you have easy conditions (good paper and a good printer) then you likely won't see a difference between printing from an 8 bit file and a 16 bit file. If the printer/media combination has trouble in the shadows and/or the highlights, then the highlight/shadow detail may need a strong manipulation before being sent to the printer. If you are manipulating 16 bit data you have a lower chance of visible banding. For instance, if your paper was not intended for inkjet, then the ink dots can spread. This can require significant data manipulation to get the highlights and shadows close to what you want. In such a situation, If your working file is 16 bit, I would advise sending that 16 bit data to the program that applies the printer/paper profile. Be wary of advice from those that assume their experiences apply to all other situations. Those that only work with high end paper, gear, and equipment, sometimes forget that those who work in the real world don't always have that luxury.

Can you show an inkjet printer profile for paper not intended for inkjet? Re: 8-bit vs. 16-bit TIFFs for printing
What profiler do you own? I can help you find instructions for profiling unusual papers for your printer. It's really not that hard. I know a local artist that prints on rice paper. These papers are used to create collages on canvas. I know a local company that buys preprinted postcards fronts, with a blank back. They custom print the backs for each recipient. There are lots of people in the world with a wide variety of needs.

Is 8One of the advantages of working with 8-bit images is they are typically smaller in file size. Smaller file size equals faster workflow which is typically crucial when it comes to both print and digital design.
What bit depth should I use for printing?BIT DEPTH AND PRINTING
Certainly, if your image is 16-bit (and requires that depth), it will print more nicely than if you were to change it to 8-bit, but that change takes place in the digital file, not in the conversion to print. Gamut is the aspect of color representation that comes into effect when printing.
