Changing a logo from color to B/W

[Bubzeebub]

I'm interested in printing a color logo in Black and white. Is this possible to do? I have a color printer.

What format is the logo?

Have you looked at the settings of your printer if you can print in black and white only?

If you have photoshop, it's easy. other programs would work just as well, but i have photoshop version 7.0 open right now and can give specifics:

-open the image
-on the top menu, go to image, then adjustments, then desaturate
-hit print

you are done. there are other (better-ish) ways of making a color image into black and white, specifically you can play with the red, green, and blue channels to balance them and get the tones you like. but that might be overkill for what you are trying to accomplish.

also, people who are really into black and white often have complaints about inkjet printers and their inability to produce good black and white tones and gradation, but that's more a photography thing and probably won't matter for your purposes.

Like dan says; if you have photoshop you could use that to remove the colour info. Alternatively, why I asked what the file type was, you might be able to edit the original design to your own spec.

If it is an editable EPS you could use illustrator or freehand which would give more control on the quality of output i.e. Selective contrast, so colours that have a similar tone and different hue are chosen so they are complimentary and contrasting shades of grey.

thanks folks. I just wanted to get the image b/w for regular printing purposes. The idea to Desaturate in Photoshop worked perfectly. Thanks again.

One other point I should note. I tried inserting the logo into a Word document and it printed. However, even though it was in B/W, it came out faded. The other normal text in the document printed out normally. Do you know why that could be?

Assuming our versions of MS Word are similar, there are some adjustments you can do directly in Word. Try right-clicking on the image, then select "format picture". Try darkening it a bit using the brightness slider and see if that helps.

I would suggest you go back to your coloured image in Photoshop. Then use IMAGE>MODE>GREYSCALE to convert this to B&W. Then locate the 'Info' palette and watch this while you move your cursor over the image. With the cursor over a shadow area which you want solid black check that the info palette shows "k 100%". Also check in the highlight area that you want pure white. This should show "k 0%" in the info palette. To adjust these values go to IMAGE>ADJUSTMENTS.LEVELS. Here you can darken the shadows and lighten the highlights until you have good detail contrast.
Make sure you have the 'preview' box checked in the levels adjustment window.
Now the logo should print only in black and it will look cleaner than just de-saturating the coloured version.
The process can be done in less time than it takes me to type this.

.jpg, .eps and .tiff formats. I printed it and it came out faded in b/w. It may be my ink is low. I'll replace the ink cartridge and post results here.

It could also be that the b/w versions of your colour tones are not very contrasty.
That is to say, just because purple stands out quite well on blue, when converted to B/W the two are not so far apart.......
I mostly use PSP and adjust the curves (must be contrast/brightness control) which is also available with PS, to get a better contrast for B/W use.
Half the design ability when working with logos is the ability to design for full colour and for cr***y fax printing, with the possibility of tee shirts and beer mats close behind!
