The Preflight tab in the Print dialogue often says "Image resolution below 96 dpi" when the Object Properties panel shows all the images to be well over 96 dpi. I just checked this by making a new doc with one image. What's the story?
Thanks,

Hi Janet,Ronnie has this perfectly correct.Let me add.1. dpi is printer's jargon for dpi per color. It's identical to ppi in CDGS.2. Here's the size dialog in PP from my camera. It's completely misleading. So is the similar dialog in Photoshop.-- There is nothing in the scene or in my camera which is 72 dpi (aka 72 ppi).-- There is absolutely nothing in the scene or in my camera which is 55 x 41 inches.Pixels by pixels is the fundamental unit for raster images. For cameras, it's formed by a rectangular array of light sensitive diodes on the CCD. This array corresponds exactly to a pattern of tiles. Each element (pixel, tile) consists of three light sensitive diodes (red, green, and blue). Thus each pixel (tile) gets one out of 16.7 million colors.So what happens when you want to print the image. People want to know the physical size of the print which they will receive. Some people would like to know the resolution.So now, you have to be careful about the size dialog. YOU CAN NOT CHANGE PHYSICAL SIZE AND RESOLUTION at the same time. They are linked together by the basic pixels by pixels of the image. I don't know anyone who wants a 55 x 46 inch print to keep in their wallet. So first off, you specify the size in that dialog. As soon as you change the physical size, the dpi pops out to a new value. That's life.
If you own a calculator and remember algebra, here's the relationships between pixels, dpi, and physical size.
total number of pixels = (dpi x width) x (dpi x height)
You're stuck with the total number of pixels. You can change either width and height or dpi but not both.
Of course you can "resample" the image to change the total number of pixels (tiles). However, it is then no longer the same image.
I no longer have X5 on my computer so I can't comment if what you see is a bug or if that's what the printer driver will do. You'll find out from the size of the print when you print.

Myron said:Janet, I believe all raw images from any digital camera or phone come in at 72pdi but vary in actual dimensions. I see it as a classic sign that an image has been tampered with if it comes in other than 72dpi.
Hi Myron,
I've been shooting my own jewelry (I'm a goldsmith) for many years with an Olympus C-2500L Digital SLR. It doesn't shoot raw. Also, as far as I know, very few smartphones shoot RAW. I was hoping to get a smartphone which can take RAW photos so as not to have to get a new digital camera, but I am finding that to be rare. Wanted to get a Samsung Note 4 because of the large size and stylus and great reviews on its camera features only to find that I will have to get the new Note 5 to get raw capability......
