Does anyone have experience printing 11x13 and larger ink jet prints? I just bought an Epson 1270 so I can print larger photos. How many pixals should my have to capture enough data to print large prints? Any info will be appreciated.

Thanks,

Marcia :) ;)

Well, let's say you want to print at 150dpi so we have:
150dpi x 11 = 1650 pixels
150 dpi x 13 = 1950 pixels

This is a non-standard ratio as digital cameras have a 4:3 ratio. Thus, we have to take the 11 as being the 3 potion in order to get a sensor that's big enough.

1650 over 3 is 550. 550 x 4 is 2200 pixels.

This means we need an image sensor giving 2200 x 1650 pixels or 3.63 megapixels.

As the nearest above 3 megapixels (which is too little) is 4 megapixels, we have a result: You really need a 4 megapixel camera.

For a studio quality print 300 dpi is the defacto standard, and ~180 dpi would be my personal minimum, for normal viewing (about 3-5 feet away). 6MP (from my D70) will yield a nice print at 13 x 17 on an Epson 2000P using matt paper.

Like Rhys, I have used 150 and even 120 with mixed results, depending on subject, color, and paper. All-in-all still generally acceptable at 8 x 10, but 11 x 13 is pushing it.

I have a couple of 8 x 10 prints from my old Nikon CP900 (1.3MP) printed on an Epson 870 that actually look pretty good (~120dpi). So your milage may vary.
