    Set the resolution between a low of 180ppi and a high of 480ppi at the size you desire. IOW, go into Image Size. Turn resample off. Set the size you want for the print output. IF the resolution falls anywhere between 180-480, you’re set to go.

    What kind of printer?

    If you want to dig deeper into this, we did a show with Andrew Rodney on resolution.

    Hi Santoro80

    I think you got it.

    If you are using the Image Size dialog to change size for print here is one approach

    - With resample unchecked, set the dpi to what you want on final print. The dimensions should now be larger than your final print if you have enough pixels to downsample
    - With resample checked, now change to the final print dimensions that you want. This will keep the dpi the same and adjust the pixels appropriately.

    If my main focus is achieving a specific file size, I typically use FIle > Save for Web and Devices. It gives me all the options I need on one screen including jpg compression quality with previews of the results. (It's not just for Web and Devices Hope that helps.

    It makes sense. If I understand it correctly... lets say I want to decrease document size for print... when the resampling is checked, then the pixel resolution decreases too and the quality of the printed image would be lower than the quality of printed image with resampling unchecked (and pixel resolution unchanged)?

    If you want the number of pixels per edge to change, you have to check the resample option. If you want to just change the DPI around with the same number of pixels, do not check the resample box. Hope that makes sense.

    started a topic Photoshop: Image resizing vs image resampling

    Image resizing vs image resampling

    When should check or uncheck the "resampling" option in image size dialog box? If I'm chaning the document size for the print I should uncheck the resampling option, right?

    size and resolution
    by vickatter
    Hi!

    First Question:
    I'm a little mixed up with the way I can increase a file size.
    I had to do a few posters yesterday and I needed a final file of 70x100cm in 200dpi. The thing is that the pictures that I was using were a little smaller than that, so somebody at the studio...
