I’m creating a simple desktop background in a blue with one row of text in a lighter shade of blue. When I save this as a bitmap and replace my desktop background with it, the text is very pixelated. The screen is 800×600 and the resolution is 72. The font is Arial and it looks fine in PS. I’m probably missing a very simple step, but what is it? Thanks.

bump the resolution up to 300. (image image size). you may (will) need to adjust the type size when you do this.

What’s your desktop screen resolution set at? If your desktop is set to above 800 x 600, that will could cause the problem.

Since you’re looking to put this as a desktop background, 300 dpi will eat up way too much memory. What you should do is create a document that’s 1024 x 768 at 96 DPI. Then add your text, save it as a JPEG at the highest level and use that as your background image.

Resolution will not matter in this case. The size is 800 pixels by 600 pixels. If you’re displaying it as a desktop, your best bet will be a 1 to 1 ratio. In other words, if your screen resolution is 800×600, make sure your file’s resolution is 800×600. If your monitor is set for a higher resolution, make your image size that resolution.

PPI (pixels per inch) should not matter because your screen only displays pixels. 800×600 at 72 ppi and 800×600 at 96 ppi are the same, according to your monitor. Why? Because there are only 800×600 pixels in the image. You monitor will display a pixel as a pixel. You can change the size of the pixels by changing your screen resolution in your Monitor control panel.

Also, try anti-aliasing the text and saving as a .JPG. Windows can use .BMP, .JPG or .GIF (if memory serves) as desktop images.

[EDIT] D’oh. Cheese beat me to it. What he said.

the resolution change won’t affect file size if the resample box isn’t checked.

I suggested that to get a better look out of the rasterized text. <shrug>

A PC monitor displays 96 dpi, that’s why I recommend 96 instead of 72. The differences are so slight as to almost not be noticed, but it’s my preference to never go all the way down to 72.

But dpi (or ppi) doesn’t matter in this case. Only pixels. 800×600 pixels is 800×600 pixels, whether the pixels are 1/72" (72 ppi) each or 1/96" (96ppi). A 19" monitor running at 800×600 has a pixel size way larger than 1/96", probably closer to 1/32" (or 32 ppi). Introducing a ratio with a factor other than the actual screen resolution setting is just irrelevant in this instance.

Good point.

A monitor doesn’t know what ppi is.

An image of 800 x 600 pixels at 1 ppi would look exactly the same as an image of 800 x 600 pixels at 10000 ppi on a monitor. The file size would also be the same.

If you’re interested you can read much more about it on this page: <http://www.scantips.com/no72dpi.html>.

Oh, and don’t forget to uncheck "stretch image to fit" when setting your desktop. That’s probably what caused this whole rigamarole in the first place. 🙂

Good link, Madsen. This writer’s really taking it out on his pet peeve. Gotta love the internet…

at 72 or 300 ppi, whatever. Doesn’t matter. Irrelevant

it DOES matter while the text is vector. don’t resize at all (when you change resolutions, if you wish, uncheck resample).

when creating 2 images of 400×200. the text is at 12 points in the 300ppi image. the text is at 52 points in the 72 ppi image to get roughly the same size. both have anti-alias sharp. font used is courior (T1) medium.

Flattened it looks… well the 72 ppi w/52pt text looks better than the 12 pt at 300 (both zoomed to 300%). So I guess I’m wrong! 🙂

Interesting exercise though. <G>

I took the resolution up to 300 and higher but the text didn’t look any different. I was about to give up, when I logged on to see what replies I might have here. In the end, the problem was what Greg suggested. I had "stretch" selected instead of "center". Such a simple solution to a frustrating problem! Thanks for all the advice.

If you set your text size in pixels, you wouldn’t have to jump through those hoops. Photoshop is using the formula 72 pts=1 inch to calculate the size of the text (in pixels) based on the ppi of the file. If you set your text in pixels (which is what I was doing in my test), you can change your ppi as much as you want and you’ll wind up with the exact same thing, as long as you don’t resample. When entering the text size in the character dialog box, just use the suffix "px" insted of "pt". Photoshop will calculate the relative point size on the fly. (I say relative because the point size is dependent on the ppi. Pixels are absolute.) You’re seeing differences in the quality of the type because the text is being hinted and kerned differently at different point sizes.

[EDIT] Glad you got it, Gail!
