Letterpress is an old technique that requires a lot of time to produce a successful print. I have attempted letterpress a number of times, a few weeks ago I went along to another workshop as experiment for another project. The effect achieved by manual letterpress far surpasses any digital replication, so it's a great addition to a final piece to reflect the time and consideration taken over a project.
Letterpress does require a lot of patience (which I don't have) but the effect produced is worth the time taken. The experimentation shown here is the initial practise which will hopefully develop into a cleaner designs.
