Is my scanner good enough for the task?

Hi guys, I have  an Epson Artistan 730, and while is old, it hsa a scanner. THe scanner seems to have a Scanner Optical Resolution 2400 dpi, Maximum Resolution: 9600 x 9600 dpi interpolated...Scanner Bit Depth: 48-bit color in / 24-bit output. I don't really know what that means. Would this be enough to scan artwork? 


I have some black and white pen and ink illustrations, that I could scan and convert to vector...
But also some color watercolors that wouldn't be suitable for vectorization but could be in the Image category...Maybe these colorful artworks wouldn't work too well with the scan resolution? What do you guys think?


I also have a 16 megapixels sony cybershot point and shoot camera I could use in case the scanner fails..but I don't know if this would be suitable.


Any advice you can give me will be appreciated.


Monica

Hi Moneca. I can't see any reason why that scanner would not work. I’ve used all kinds of scanners. Just try not to make the final image so much larger than it is in real life to the point that it loses detail.

I have an older Epson scanner with about the same resolution and so far have had no problems with it fulfilling all my scanning tasks.


You need to realize some things when it comes to reflective scanners:


1. Don't expect color and contrast accuracy so you will have to do some editing in Photoshop or equivalent.


2. Interpolation just means that you are not really getting true resolution but a bumped up version where the software adds pixels to make up the difference.  However, it works just fine. The native resolution for these scanners is usually between 300 and 600 dpi.


3. Remember that there is a point where resolution is overkill so consider what you are scanning, an original watercolor image should get the highest resolution you can without choking your processor and the deepest color bit depth because the detail is there.  A 5X7 photo print does not have the resolution to begin with so you will only be capturing the blur in greater detail.


4. Black and white will work just fine in any resolution, the higher the better.


5. Remember to scan higher and reduce the resolution in Photoshop and not the opposite.


Happy scanning.
