Hi I am selecting photos for printing and I am using Print Size to check how large I may have the photos printed. What I do is I open a photo file and then select Page Setup. For example A2. I can then go to View - Print Size and my display will show the rulers in centimeters correctly. But when I tried to select A1 that size is not available in the list under Page Setup. I have tried selecting User Defined but there is nowhere to add the dimensions and no popup to allow dimensions to be added.

I use an Epson R2400 (to print up to A3) and that does not offer an opportunity to enter the dimensions for User Defined under Page Layout.

OK you Open an image file and it opened some size in Photoshop. What size did it open. You use page setup and selected A2 did you choose that size because it the size paper you have in the printer or because it the size the image in Photoshop is? What page setup size you you choose for my image

In My CS3 I do not se an A2 option or an A1 I do see an envelope A2 Have no idea where CS3 has this list may be built in Photoshop.

Printer settings are print driver settings. ]

In CS3 it look like you must first set the printer or CS3 will default to your system default printer. When I used Print in photoshop and selected epson 4800 the page setup changed it tune.

Hi JJMack What I am doing is using Photoshop to see what my photo looks like if I were to print to A2 or A1 and larger. If I select Image and Image Size and I alter the Document size Resolution to 99 pixels/inch the rulers will be correctly displaying centimeters. I had set the Page Layout to A2. So selecting View - Print size I can decide whether my photo will look good in this instance printed on A2 paper. This would have to be done by a commercial print company aas my printer is A3. What I am unable to do is select A1 or A0 as it is not an option in my Photoshop Page Setup Size list. What I could do is select User Defined but as I am enquiring there is no place to enter what User Defined sizes I want to enter.

In addition to JJ Mack's advice - the best way to judge image quality is to view the image at 100% magnification, where one image pixel is represented by one screen pixel. This is the only magnification that shows you the real image quality.

If you routinely view every image at 100%, you will have reference point, which is also useful when considering an image for printing, provided that you are viewing the image at the dimensions that it will be printed.

(i.e. you have to resize the image to the required dimensions and set the ppi value you want to use for printing)

So to get an idea of how the image will print at A2 or A1, resize the image (with Resample checked) so that it fits within the format.

A1 is roughly 59 x 84 cm, and if you start out with let's say a 24MP image, it will be 6000 pixels on the long side.

84 cm is 33 inches, so without enlarging, the image will need roughly 182 ppi. (6000:33 = 182)

If this ppi value is not high enough, you can increase it, but then the image will not have enough pixels, and Photoshop will have to invent the missing pixels by interpolation.

I can't really say which will give better results, enlarging the image or printing with a lower ppi.

Hi Per Berntsen Thanks for adding advice. I have tried viewing at 100 percent. With Page Setup to A2 size. I find that the rulers double in size - one centimeter ruler space is actually two centimetres wide. I do not want to resample my photos as this would damage the originals.
