Hi all, I have the same issues as previous posts. I have an image that needs to fit on a board 1850mm X 800mm.
My current image is 2000pix X 865pix
169.33mm X 73.24mm
300dpi
Bicubic
My problem comes in the small image on the sign. The image(logo) is NOT a vector image and is only:
376pix X 157pix
31.83mm X 13.29mm
300dpi
When I enlarge the image, the text and the other logo which is a vector image is fine, but the non-vector image looks terrible.
Boss told me I have to make it work, he said its been done before.
Need help please.

If he says it's been done before, I suggest you ask him how. The way you're describing it, it should look like crap, just as you say.
You could try upsizing the image in Photoshop, with Bicubic Smoothing checked on for the interpolation, that might help. But that will only take you so far.
Others talk about the 10% increment thing. Frankly, I tried it one day, and didn't see a big difference between doing it that way and all in one shot. In fact, doing it all in one shot, with Bicubic Smoothing selected, seemed like it had a better result.
As I said, though, this will only take you so far. Do you have any idea of the viewing distance for the sign? You can get away with some stuff if it's only going to be viewed from far away.
Also, you didn't mention how this was going to be reproduced. That can play a factor in the quality.

NO it will not be reproduced, It is for the sign to our office.
It needs to be high quality both far away and close up. The original sign was done in vinyl so the edges were very smooth. This one will not be in vinyl because there are too many colour patterns now.
As for the boss, he does not know how it was done, just that it was done before.
If I manage to find a vector image of the logo, can it then be expanded to any size.
How can I create a vector image?

Ick... That 10% Increment Nearest-Neighbor method works like carp!
I heard it said on one of NAPP's (National Association of Photoshop Professionals) podcasts. NAPP publications are usually very knowledgeable and useful, but that was the stupidest thing I'd ever tried. :rolleyes:

1) Yes.
2) Trace the image in Illustrator, Freehand, or Corel Draw.

I completely agree. On one rainy day for the anally retentive, I decided to try that, and compared it to the one shot method, and also to a demo of Genuine Fractals. To my eye, and the eye of an eagle eye art director, the one shot method using Bicubic Smoothing was the best result.

By far... Photoshop is quite advanced in this. If it was a 16-bit image, you could do miraculous things with it.
Personally, what I like to do is, if I want to double the size, I'll triple it first (with bi-cubic smoother), apply a slight gaussian blur, then resample back down to 'double-size'. This is what I learned from one of the photographer's forums, and I found it to work quite nicely. It removes the artifacts from upsampling, and maintains close zoom-in detail that never existed before.
If the blur is too much, but still necessary (ie, upsampling from a real small or poor-quailty image), then I may apply a high-pass filter on soft light to sharpen it.

Gonna have to try that, at least with the 16-bitters we get. Thanks Ned. :)

Let me ask a dummy question. Where and how do I Bicubic Smooth something?
Edit => Image Size
Resample Image checked.

How complex is the logo? I'd say save yourself the headache, make your boss happy and redraw as a vector. Any company that doesn't have their logo as a vector should be....well, you can think up a punishment. Besides, you'll have the logo as vector for ever then for use in all your other corporate things.
