300 DPI and paper sizes

1192 views6 repliesLast post: 10/21/2005
HI

I would like to create images that will fit Letter and A4 sizes precisely, without borders.

I have turned to Photoshop CS2 as the application that will allow me to do so. It allows me to, I think, create a "New.." document with a "preset" at the A4 size.

But when I choose 300 DPI at this size and create a new image, it creates a HUGE document which shows up at 16.7% on my screen.

What is the best way of working with these files? The fonts seem to be too small on the screen.

Thanks for any ideas, or pointers to websites I can read up on.

Hard to do.

How many pixels did you start with?
How many pixels do you have now?
These two numbers should be the same.
Did you uncheck interpolation?

I started with 72 DPI. Now the printer asks for 350 DPI. When I change it to 350, the page size becomes huge and the image becomes very small. If I start with a 350 DPI image and then copy/paste my current image into it, it becomes very blurry. So, my question is, how can I make a 72 DPI image into a printable one?

Well......
In PS7 it seems the default screen image is 72dpi which is an artifact of old monitor res. A modern monitor will give proabably 95 dpi - and an lcd 120 dpi---SCREEN RES - which is different from print res. SO.....a 300 dpi shot will look immense on the monitor because it shows 95 of those 300 dots in an inch^2; you end up with more inches of screen.

Print res is altogether different; as is the issue of resampling. In the options of ps7...you can designate print and screen res. Use the zoom feature to fit it on the desktop...clips though.

Anyway...the actual print size is either an option (A4 is amongst them); or you can create your own custom sixe by editing the " new doc sizes.txt " file int the preset folder in the photoshop directory set. You can tinker with that to get a print size that exactly fits you photoshop to paper flow thru. It's daunting because the more elements in that chain..the more variation you get( eg...photoshop print mnger to 3rd party print driver/mngr, to windows print obj to printer and paper).

Btw.. a custom crop setting, if appropriate for your use, will work too.

CS2..i dunno? Have ver 7.

I would add my two cents as well.
Your claim your pic is 72dpi.
I assume you verified this in Photoshop.
What size in inches was that when you went to image/image size in Photoshop? Were you attempting to print that size on your printer?
Or, were you asking your printer for a different (larger) size?

I suspect you were asking your printer to print your pic larger in inches than Photoshop said it was in.
Why don't you increase the dpi and the size of the pic in inches in Photoshop to match the paper size you wish to print it on? Then you can send it to your printer.
