resample or print at lower resolution? - Adobe Photoshop Elements

I print most of my images at 240 dpi. I can print 8x12's and 11x17's at this resolution with no problems. I want to print some 13x19's, but this brings my resolution down to 200 dpi. I know they will print fairly well at that resolution, but I am curious to know whether printing at 200 dpi will create a better print than resampling to 240 dpi and then printing. I also have a few smaller files that will be 150 dpi at 8x12, and 120 dpi at 11x14. I am assuming I will have to resample these images, at ...

    Eric,

    I think printing anything at less than 200ppi is an iffy thing, but it depends on what is 'good enough' for the individual. The nature of the image and level of printer will affect outcome. I would try selecting just a small portion of an image and running two tests, printing at a lowish resolution and resampling to 240 and compare the two. This way you'd have a side by side comparison without wasting a lot of paper and ink.

    edit: this is just my 2 cents worth, of course

    As Nancy says, the best bet is to just try the different combinations you're
    considering and compare.

    As for whether to do the resampling in Elements or let the printer do it,
    again, that just depends. The latest Epson drivers have an "Advanced"
    option to "Smooth Edges", which is supposed to do some anti-aliasing on the
    input image. But Elements will do something similar. Which does a better
    job? I don't know. Best thing is to try both and see. :)

    Eric, there was a thread a while back about upsampling. I think it's Leen that does this quite a bit when going after some of those large photos of his. The concept was to upsample in 10% increments, with bicubic checked in the Image>Resize box. Maybe either Leen or Chuck will come on and give more detail.

    Wouldn't the amount of detail in any given image also have an effect on how successfully it could be upsampled?

    It was me.
    There is very little to add. Upsampling in increments of about 10% always does the job for me.
    Probably a lot of detail like extremely detailed tree branches in a winter landscape might cause some problems, although I never had any problem.
    Once I read in a rather specialised Dutch magazine for digital photographers that bicubic upsampling like in Photoshop won't cause any problems up to 4x the original size. I tried with some portraits and they appeared to be right.
    With my 6 Mp camera that automatically upsamples to 12 MP (Fuji S2Pro) I often print my images at 20x30 inches (50x75 cm) at 254 ppi and I cannot notice any degrading of the image.

    Most of my portrait and wedding images are sold varying in sizes between 12x16 and 16x20 inches and printed at 254 dpi.
    Why 254 dpi? Because 5000x7500 ppi is exactly 50x75 cm. And I'm used to working in cm. ;-)

    Hope this helps.

    Leen,
    I follow all this, and I'll try it this weekend. There are two ways I am thinking of to do the upsampling:

    1. Set the dimensions to the print size I want, then upsample the resolution in 10% increments.
    2. Set the resolution to the desired setting, ie 240 dpi, then upsample the dimensions in 10% increments.

    Does it matter which order I use?
