For Print, what is the best render settings for clear ,clean images?

    I'm afraid this is one of those "how long is a piece of string" type questions.

    What kind of printing are you wanting to do with your render? If you are using a commercial printer, do you know what their file specifications are? Do you know how big a render your computer can handle? Do you know how big the printed render needs to be?

    These are just some of the things that can affect preparing a render for printing, and the settings will be different for each one — there is no such thing as One True Answer™ that will work for everything.

    I like the '42' render setting myself. Seems to work for all applications.

    Screen use resolution is most often 72 dpi.  The DPI does not matter for web, only for print.  

    In an image editor, such as Photoshop, you can set your output resolution, say 600 DPI and the size in inches, say 8x10.  http://prntscr.com/8shnd6

    Then you change the inches to pixels and that will give you the number of pixels, 4800x6000, so that is your target size when you render.  http://prntscr.com/8shnho

    However, your second hurdle is then converting to CMYK.  Print colors are duller than screen colors of RGB.  You may have to work on the image and adjust colors, but it is imperative to change the color space to CMYK, so you have a better idea of how your image will print.

    You might also want to make sure your monitor is calibrated. So you know your colours - those you're seeing - are the ones your system wants you to see. I think that made sense, but still waking up here, bad night /nod

    The render will have to be done at print resolution and for most printers that would be 300 PPI. Although printing is in DPI the printer driver makes the adjustments. Changing the PPI/DPI in Photoshop after rendering wont work unless there are enough pixels for the size requested. At 300DPI that would be 3000x2400 for a 10"x8" image and any size below that. For larger sizes the DPI/PPI can be lowered, think of a billboard where the image is 60'x20' yet the DPI/PPI may be as low as 4DPI. All the images I use for the internet are set at 1000 pixels wide and 0 ppi or 1 in Photoshop as it wont allow 0. That way if anyone tries to print one the largest size they will get at 300 DPI is 3 inches and if they try and increase the size to get a bigger print it will come out pixilated but still take up 1000 pixels on the screen no matter what resolution the screen of the viewer is set at smiley 

    This is worth reading through.

    Remeber you can do simple maths in the numeric boxes in DS - so no need to use Photoshop, just take the final (bleed) size you want and mulitply by the final PPI value then enter the sum in the size fields - e.g.

    8*600

    and DS will turn that into the right number. Remember to make sure that resample is off when setting the PPI value (or preserve image size is on - the naming of the option varies from application toa pplication, you want to keep the pixel count the same and change the reported physical size).

    Well, this really depends on the needs of the printer. These days, if printing on high speed digital, you'd most likely keep the image RGB, because that's what the RIP in the printer will expect. This varies between printers and the age of their machines, and their workflow, so it's always important to ask first.

    Again, "42" is the correct response to a half-sentence question that qualifies for an answer the length of a book.
