Hi,
Is it possible to change the export document resolution settings of the PSD files form the current 72 DPI to 300DPI?
I realise most of the work is for digital/screen use but I would also like to print out some of what I’m producing and scaling up in PS is ok but they never print as well as when they are initially at higher res.
Thanks
You don’t have to scale up or resample in Photoshop. All you need do is set 300 pixels per inch in the image size box, but don’t alter the actual pixel dimensios of the image, ie make sure the “resample” box isn’t ticked. You can also set 300ppi as the default viewing in PS preferences.
In ZBrushCore you are limited to the size of your screen, so on a larger resolution monitor you’ll get a bigger image. And that will determine the pixel dimensions of the image you can export. There’s no way to change that, so it will limit the size of printed image (if you change the dpi to 300 in Photoshop without resampling).
Thanks Dillster,
I know you can increase the DPI but PS has to decide how those 75 DPI pixels get split into 300DPI and it doesn’t always do a great job with big jumps like that.
I do a lot of other hi-res photos and photoshop work and have never found it that good to upscale like that when trying to print at hi res as it ends up going fuzzy in the smaller details but I’ll try with these images and see how I get on. Cheers.
Thanks Marcus,
Overall the image size (dimensions of 50cmx30cm) is fine, it is more the export resolution itself but again, I’ll try upscaling the DPI and see how that goes.
Cheers
You’re misunderstanding dpi. What matters with an image is the pixel dimensions, the dpi just tells the output device - such as a screen or printer - what size to display the image.
When you change the dpi for an image in Photoshop you have two options: to use resampling or to not use resampling. If you use resampling then Photoshop does as you describe; it increases (or decreases) the pixel dimensions. This can lead to the image degrading.
The alternative is to not use resampling which is what both dillster and I are talking about. The image quality remains the same, as the pixel dimensions aren’t changed, but for higher dpi the image will appear smaller.
An image of 50 x 30 cm at 72 dpi will have pixel dimensions of about 1416 x 850. This same image could be printed at 300 dpi which would give an image of about 12 x 7.2 cm.
Thanks Marcus,
Sorry, I think we’re talking at cross purposes. I do understand about the pixels, but I wanted to retain the image size as well.
That’s ok, I have some other workarounds I can use. I just thought if there was a way to change the original exports resolution setting then it would be easier and less finishing work.
Thanks for your help 
If you’re keen to create good renders of your models, with the ability to produce print resolution images, you might consider the ZBrush to KeyShot Bridge and KeyShot for ZBrush:

Cool thanks Marcus.
I’m only just delving into the whole 3D world at this stage (which is why I started with Core) but may look to upgrade to the full version and Keyshot later.
Cheers
Just to clarify for others reading this thread: the ZBrush to KeyShot Bridge and KeyShot for ZBrush will also work with ZBrushCore.
To add to Marcus post, and for anyone using the Rocket 3F modeling software and Keyshot for ZBrush. You will find the Rocket 3F to Keyshot Bridge will also export geometry to Keyshot for ZBrush. This overcomes the limitation in Keyshot for ZBrush that only allows importing of .bip files or direct bridging from ZBrush.
I discovered this when I downloaded the free trial of Rocket 3F from here: https://rocket3f.com/
