I've been learning all about logo design, typography etc in my own time and it was going quite well. Until I was researching what file formats to give to a client, and I saw that for each file type you should provide full colour, spot colour, black & white.
So I looked up spot colours having not heard about them before and I get what they are now. However i'm still confused as to how to use them in the logo design process.
I understand it's complicated (/impossible?) to convert CMYK to spot colours, so when you add colour to your logo designs do you first choose the colours in pantone swatches and then convert to CMYK after for the full colour version? And are you supposed to leave pantone reference numbers for the colours used in the file somewhere, or will the printer know which you've used anyway?
And finally can anyone recommend a pantone swatch book to buy, as I wasn't sure if I was looking at the right books on Amazon.
