Don’t send me an email unless you really must!
The best way to specify a job for letterpress printing is to work from a sketch or specification on paper. Clients frequently contact me by email with a request for a job that they can see in their mind’s eye, but until I can get a clear idea of the dimensions of the thing they want to print I don’t even know whether it will fit onto one of my presses.
Designers who send me PDFs may not be aware that if the job’s going to be set in metal type then there are only a limited selection of typefaces available.
So although of course I welcome correspondence in all its forms my recommendation is to arrange to meet face to face at the workshop, if possible. That way we are much more likely to produce a design that will print successfully.
