Snapfish and large prints

[DueyDooDah]

I'm having a bit of a problem getting large prints (poster size) via Snapfish. I shoot 3504x2336 RAW format photos. I process them in Lightroom and export JPGs at Quality 100 in sRGB space. I do not Resize to Fit and leave the Resolution set to 240pix.

When I use the Print Poster option in Snapfish, I get the little warning triangle that suggests I do not have a high enough quality photo to print an acceptable poster, either 16x20 or 20x30. Looking at their chart, All it takes is 1800x1440 or 2700x1800pixs for an acceptable photo.

Anyone have any ideas what's happening here? Is LR squashing the photo during export? It looks like it as JPG file metadata shows 2927x1951pix. Is there a setting I am missing?

try changing your resolution to 300 and see what happens..

Tried it. Didn't work. I even went to Photoshop and saved to set to a 20x30 document size, which required me to use 110pix resolution.

OK. Found my answer. It was on the Canon Learning site. Unfortunately, I am unable to get the quality I want for posters. The jist of it is that to get great quality, image size dictates output size. To determine how big a print can be in inches, of suitible quality, you need to divide the image width and length in pixels by the resolution you need the print to be, which is normally 300pix. So, if you have the dimensions I mention in my first message above you would have:

2927/300 = 9.75 inches
and
1951 = 6.5 inches

Note I used the dimensions of the JPG file. Because this is the size going to the printer, Snapfish in this case, this is the maximum size you can have printed without warning. Although, I sent in my photos at 240pix resolution so was able to print up to:

2927/240 = 12.2 inches
and
1951/240 = 8.13 inches

My 8x10 inch photos looked fine at the resolution.

what if you convert your raw to tiff..

You can get a software called Genuine Fractals that will allow you to blow up your photos without losing too much resolution. It's meant specifically for processing larger sized prints. For a poster sized photo, you may end up with a 49 megabyte image for example. Google Genuine Fractals and their website should come up. There are tutorials on that site on how to use it as well.
