Fixing aliasing

[Aaron2004]

Hey all!

 

I have a small jpg of a company logo that I need to make larger. It is a pretty simple logo with solid colors. I tried taking it into Flash and doing a bitmap trace, but some of the text has serifs on them and they get too rounded off. Is there some combination of filters that will fix aliasing in photoshop?

 

Thanks!

here's on approach that works pretty well.....

 

 

+Size the image to what you need

+convert to Lab Color

+Go into channels and gaussian blur the lightness, A & B channels until the pixelation is gone.

+Go back to the lightness channel, do a levels adjustment.

+Adjust the black and white until the lightness channel has a sharp edge...as close to where you want it as possible.

+Check the image in full color, if the colors are bleeding past the edges....use the lightness channel to create mask. This should when applied to the image layer effectively mask any blurring of the A&B color channels.

 

Hope it at least steers you in a helpful direction....

Cheers

trace the logo using vector shapes in PS, then you can scale it to what ever size you want.

wda,

 

Thanks for the advice....I tried it and I learned some things while doing so...I never used the lab color model before. However, it still came out too blury. I might have to go with jat's advice and just trace the silly thing.

 

Thanks!
