Hi,

I’m using Win 2000, Photoshop CS and creating a very simple artwork: a text line (my name for instance) in Arial, black, and then saving it as a JPEG, 300 pixels/in, 3"x2", on a WHITE background. Nothing more.

When I save, close and then re-open the file, i get around the letters of my name extra pixels (greyish) that were not there in the initially created file. They show up when I re-open the file. So now the artwork looks "dirty".

Any idea what is going on and how to fix this?

Thanks a lot
Suzanne

That’s because you’re using JPEG – a lossy format.

Probably compression artifacts.
Try saving as higher quality (less compression) JPEG.

Also, try different text settings, like Smooth under the AA box.

In case Suzanne isn’t a computer ace (or other later readers of the thread) I’ll define some terms.

Lossy: this term means that a format (like jpg) makes files smaller by removing or changing data. It is the probable cause of "messy" edges to the text. The more you compress the file (smaller compression number) the worse the messiness gets.

AA: Mac means anti-aliasing, a system where text is made to look smoother on slanted and curved strokes by using grey tones (in a black and white) instead of stair-step transitions. You have three or four different levels of AA in Photoshop.

Finally, remember that jpg is the preferred format only for web work that is photographic in nature (that is what the p stands for). Gif is better for images with large areas of similar colors, such as you describe. And tif is the best compressed format for non-web work … it isn’t lossy, so you don’t lose detail or see things get messy.

And of course, always keep an unflattened PSD version, because you will find you need to change that text some day.
