What is the easiest way to remove the background color from the scanned item on this page:

http://www.inwoodbarbershop.com/services.htm

What can/should be done when scanning that item?

Desired end effect must be just black and white (no color).

Thanks.

Mark,

I assume that you are referring to the "coupon." I’d scan it in color, then use Replace Color in PS and choose white. If you scan in B/W, you’ll have a pretty dark grey to deal with, and the orange will be easy to hit with the eyedropper. You could also use the Magic Wand for the orange, Invert the Selection, and Fill with white.

It’ll be interesting to see what other methods, folk come up with for this.

Why would you scan it ?

Just save the picture.
then, in photoshop, view just the red channel.

Black and white I’ll bet (haven’t tried it though).

I got most of what was desired on that tiny 24kb jpeg.

Scanning at as high a resolution as possible – 1000dpi if possible. Then boost the contrast.
In Layers, double click on the background and change to Layer 0. Use the magic wand to select the orange then press backspace/delete.

This should remove most of the colour. Use the eraser to tidy up the picture.

Wow. That’s a complicated way to do it.

Try this instead:

You want the final image to be black and white, no color. So scan in grayscale, not color. Then use the Levels command to drop out the gray background by sliding the white point slider. Should take about two or three seconds.

Yeah this works very well. Interesting, I deleted the blue channel and was left with cyan and magenta, from there the cyan channel worked then I had to convert to greyscale to save as jpeg. GIF might be better though no way to make that one look decent in true B&W bitmap with all the gray tones.

My first thought would be to:
while in RGB adjust levels, or hue saturation to lighten the background color.
Then convert to grayscale.
Then go to levels and use the white level dropper on the background. Then go back to contrast to darken the remaining blacks. Then Clean with eraser as needed.

Probably the simplest thing to do would be:

Open the original download
Solo the red channel
Do a print screen
Open a new window and then paste.
crop
maybe a little unsharp mask
save as anything

You never leave the rgb color space.

Desired end effect must be just black and white (no color).

Scan as grayscale, or scan as color and then Image -> Mode -> Grayscale.

If the background is too gray and/or the text too dark, or if there’s not enough contrast, you can use Image -> Adjustments -> Brightness/Contrast to find something you like.

OR… You can do it the way the pros do: Image -> Adjustments -> Curves and then pull the end points inward (that is, pull the bottom left thingie to the middle in the bottom, and pull the top right thingie to the middle at the top). Tweak this curve as necessary, then click OK.

HTH.

Now, where’s my free haircut?

It might be more accurate to try to duplicate the font (closest one in photoshop) and recreat the ticket. At least if something goes wrong you can go back and change colors or print.
