    If we are to perform any sharpening, it should be optimized for 300ppi right?

    Or to put it another way, what are the optimal resolutions for each print size?

    Some info on this:

    Benefit of using a file in excess of 300dpi - no, unless you intend to print it in 4R, 8R and 10R all from the same 1 file. In any case, the Frontier should be able to perform some sharpening for you.

    Assuming your pix is already, say, 1800x1200, USM in PhotoShop will be more than enough.

    Reso for print sizes (on Frontier / FDIs) -

    4R - 1800x1200
    5R - 2100x1500
    6R - 2400x1800
    8R - 3000x2400
    S8R - 3600x2400
    10R - 3600x3000

    So long as you keep to this approx res, you should be okay. Just remember not to push the details of your image right the the edge of the 1800x1200 (or whatever res you are using). There may be a 15-20 pixel crop-off in some cases.
