All designs look great. However, we are not opposed to changing slogan. Our name is Printing Master Services but our clients have come to call us "PMS", or "Printing Master". We are open to all ideas and slogans. We are looking for a new look. There could be a description of our services on the logo also. See what you can come up with.
I would watch out using color swatches and PMS being used sometimes in the logo without Printing Master etc attached, you may run into problems with Pantone. Maybe not, but with a company that large if they had problems with it, they've got the money to threaten, and a lot of large companies will do it whether they end up following through or not. It just makes more sense not to take the chance, I think.
yeah, i'm a ccccop. No, actually i am someone who has had customers that have not taken that kind of thing into consideration and later had to redo their design and reprint their product. Copyright law is something that large companies don't have any problem trying to enforce even if it is questionable.
