Some people say they have no problems printing on vellum. Why do I?

First, some people haven't yet run into difficulty if they haven’t tried fancier papers such as pearly vellums or mulberry paper, and others don’t realize their printing could be greatly improved. Secondly, there are significant differences between ink and paper brands in how they work and how long they take to dry. Thirdly, different ink types yield very different results.
