Your printing may need some pressure!
Over a year ago, students in my Art 356 Print Production class designed layouts for a tutorial hand-out on Pressure Printing, also known as Stratography.
Tracy Honn provided the text from a hand-out that she used at a conference. I took photos of Carol Parker’s book that she created when she was in graduate school along with the original plates. Tracy Honn and Sarah Noreen printed a demo for photographs at the Silver Buckle Press. Two solutions are available for download. Alyssa Grabski’s solution is here. A link to Meg Neuville’s is here. Let me know if you have any questions.
