Wierd lines in photoshop

Check the anti-aliasing that the text is using.

check what your zoom level is, photoshop is displaying pixels so it wont show smooth text unless its zoomed 12.5, 25, 50, 100, 200 etc,so there is no interpolation of pixels.

well its not the anti aliasing and not the zoom, what i did found out the there is a remarkable difference when i open a new document in Photoshop CS and choose square pixels instead of d1/dv pal 1,066.
When using square it is almost all gone those 'wierd lines'.

But it is still wierd....

any other suggestions?

Check that the pixel aspect ratio is square too. It's under the "Image" menu.

okay thats good to know, whats the difference then between them, square and d1/dvpal 1,066. i only know that dvpal is used for tv.

well what is the workflow for you making that image? If you didnt use square it will appear to be messed up. D1 is for video output, like DVD and broadcast-which uses rectangular pixels, so the aspect ratio will appear to squished or scaled. If you are creating things in Photoshop, you want to use square pixels, that way its easier to work on visually- then resize your image to whatever aspect that youre sending it to.

Its to do with the image resolution and your physical screen resolution.
Fonts are normally vector files (with bitmap overlays). They are rendered at the physical screen resolution - therefore look smooth at most scales and zoom levels.

Photoshop renders the bitmap at the resolution you define in the document. If this is greater than physical resolution (eg. 300 vs 96dpi) then pixels will have to be lost and shortcuts are taken.

Tip - use vector images when placing bold type.

what your seeing is non-square pixels displayed in a square pixel aspect ratio still using non square pixels. Unfortunately theres no way around it, if you need to work in non square then so be it. You cant change the res afterwards to get the wider aspect ratio because it just adds more pixels rather than changing the aspect ratio of the pixels.

Computer monitors display in square pixels, however u can get tv resolution monitors for ur computer. this is just an abnormal effect on computer monitors, but on TV, it will look smooth. Its trying to disply "rectangle pixels" on a square pixel display.

A way to make it easier for u, would be to create the image at 720x540(for computer monitor view), then duplicate the final, and resize the duplicate to 720x576(for tv). So u can get the effect u want visually on the computer monitor, and then when u go to TV, it will effectively be the way u had seen it on the monitor as square pixels.

The edging will only ever affect the quality on computer monitors, not on TV.

I hope that helps.
