    I am in the process of redesigning a postcard for a client and they need it so it can be printed at 300 dpi. I am doing this project in Photoshop and the only related option I see is ppi and I know that is for screen resolution. I know my graphic design terms, but I have to brush on my printing knowledge. Can someone fill me in real quick on how to get this document to be printed in 300 dpi? I will not be printing it; I am just redesigning it for them.

    Oh and they also requested the bleeding to be 1/16". I know this is possible in Illustator, but how would I do this in Photoshop? Thanks a bunch!

    Most of the time they are asking for a PS file at 300 ppi (pixels per inch) to be printed at 150 dpi (dots per inch). The general rule is that ppi is double the dpi. Most color presses run between 133 to 150 dpi. 300 dpi seems high, I would check with the printer again. To create more bleed add 1/8" to your Canvas size in PS (Image/Canvas size). Don't do this in Image size, that's different. You may have to clone your image outward to fill to the new edge. When you bring this into a layout program, you will need to see the whole image with bleed, then you will be creating crop marks that will show the finished size inside the bleed. Hope that gives you a start.

    Mac since 7.5
    We output most everything at 175 line, occasionally running as high as 250 (the upper reliable limit of our Agfa plates). Most printers I know output film/plates at 150 or 175 line screen, and want images to be 300-350 dpi at the actual printing size. In other words, an 4 x 5 image at 300dpi that is being enlarged 200% to 8 x 10 will have half the resolution and look like crap (to use a technical term ;) ).

    Thanks for the help, guys. Unfortunately they are already going with someone else. Oh well, it happens to all of us. :rolleyes:

    At least I got the information down. :)

    Sorry you lost the job, but FYI

    Though a bit dated the info at this site is still relevant:

    And probably the clearest explanation I have found on-line.

    But this one is shorter:
