hi all... so here is my dilemma: i've want to make a catalog for printing in Photoshop and it will be in black&white... so my question is... what image mode should i use: Greyscale or CMYK?? and what and what type of colors should i use? are there some special swatches for working in Greyscale? sorry but i'm new to printing and all... any help would be much appreciated! thanks in advanced!
