Enlarge document without blurriness??

I apologize in advance if this isn't the right forum. Please move this if it's in the wrong place. I have a photo of a chart that is too small to read, but when I enlarge it it's too blurry. I tried printing it to possibly scan it bigger, but it printed unreadable. Suggestions please?? Thanks. Ed

 

Hmmm...

Not really a lot you can do here, however I might try rescanning at a higher dpi, say 600 and see what that yields...

If you have Photoshop, try Filter > Sharpen > Unsharp Mask

And another paid solution would be http://www.focusmagic.com/

 

Thanks. Unfortunately there is nothing to scan. I received the document in an email. I tried to print it so I could rescan it, but it printed worse than it looks in the email. I'm trying to get the source of the document to send a better one. In the mean time I might try something with my wife's computer. She has a new one with alot of photo 'stuff' on it. Ed

 

Please post back any thing you find that helps, OK? Thanks...

 

Good point, lossy JPEG (lossy) is not the best choice here. TIFF or PNG, both lossless, will do better. TIFF can be saved as lossy or lossless, be sure your correspondent saves them as lossless. If they can send you a PNG version as well, you can experiment a bit to see which one is to your liking...

A bit of technical comparison of the formats is here:

If you tell us what photo software you have for enlarging we may be able to tell you some settings.

An old trick to enlarge images and have them not get all blocked up is to enlarge in small increments. Rather than enlarging 400% you'd enlarge 25% multiple times. It will give you less blocking noise and less jaggies, although they will still be there to a degree.

 

This method is worth a try if you use PhotoShop, as is the Online Image Resizer.
But if the original is a JPG or very small to start with, decent print quality is not gonna happen...
