A black and white greyscale version of your logo is a version that is made up of tones which are in turn made up from varying sizes of black dots. A greyscale version of your logo is suitable for BW print reproduction, resolution permitting (for extremely low-resolution BW printing - FAX cover sheets, cheques, etc - it's probably advisable to utilize a linear version). This format of your logo can be either vector based or pixel based with the usual pros and cons (unlike a colour pixel based logo this logo can be reproduced using one colour printing). This type of image is most common in BW newspaper photographs.
