of my drawings and such. I watercolored this and when I scanned it, it appeared to be washed out a bit. I order a few items to check the printed outcome and the colors really need enhancing.

Any ideas on the best way to do that? I like doing the graphical but I'd rather have my hands in it so to speak, so any help on how to improve the quality would be greatly appreciated.

Whatever graphics program you have, and perhaps the scanner software itself, likely has functions to adjust the contrast and saturation. I think that would be the basic things to play with.

Depending on the software, you can adjust the channels. Most software has a collection of image adjustments. In Photoshop, start with shadow/highlight (or channels). In CorelDraw, start with contrast/brightness.

There really is a lot of hope for even the worst scans, but the quality of software will make the difference. Save a few originals in case you have access to a different program later.

If you know about layer adjustments or other functions that won't degrade the original, use them. (-;

When I scan watercolours, I deactivate any adjusting the scanner automatically does (like saturation, contrast etc...). Scanners just interpret the image in their own way, they don't know what it is, so they put too much contrast and saturate the colours, so they destroy drawings. I scan it with a high resolution, like 1200dpi, because I have noticed that this keeps more details. Perhaps it's just my idea...

After scanning it with neutral adjustments, I put the drawing next to the screen and start manipulating it until it looks alike:
-levels (whites and blacks)
-sometimes colour balance or hue/saturation, because some scanners put a coloured touch (like a green dominant, or a yellow dominant - ours in the gallery puts a yellow one, horrible!)
-then for drawings / watercolours, in order to "give some texture" like MA says, just use the unsharp mask. Sharpening gives the scan its paper structure back . But not too much sharpening either! 1 or two pixels are usually enough.

Taking a look at your cowboy rose, it looks really good, I see no quality problem - customers don't know what the original looks like to compare...

I have found scanning watercolors to be challenging too. This may sound strange but I have found a "low-tech" way of getting the colors to scan better- I press down VERY LIGHTLY on the scanner cover with my hands as the scan is made. Believe it or not it can make a difference! (Just don't press too much or it will turn out with a "shadowed" effect and you don't want to damage the scanner).
