Day/Time: Tuesdays, 6:30 – 8:30 pm ET on Zoom
Level: Beginning – Intermediate
Instructor: Anne Eder

Course Description: Get outdoors with this introduction to plant-based printing processes that use light and common plant materials obtained from the backyard, a nearby park, or even the grocery! This class is an introduction to plant-based printing processes that use light and common plant materials! It will cover anthotypes, chlorophyll printing, and other plant-based printing methords. We will meet via online platform once a week for demonstrations and students will then take what they have learned and complete that week’s assignment, returning for troubleshooting, critique, and a new demo each week. In the second half of the semester, we will explore additional related printing methods, with continued emphasis on plant material, sustainable practice, and developing a body of work.

  • Substrates—any good watercolor paper will usually work well, but consider fabric, nonglossy ceramic, wood, or other surfaces.
  • A means of extracting juice from plants—juicer, blender, mortar and pestle—any of these will work.
  • Denatured alcohol (Everclear or vodka will work!).
  • Salt.
  • Cheesecloth or fine sieve.
  • Foam or regular brushes for applying emulsion. Small trays for dipping optional.
  • A contact frame or some pieces of glass (tape the edges for safety, rigid cardboard or equivalent for backing, clamps or clips, tape, or old glass photo frame (no UV glass—we want those UV rays!)
  • Assorted blossoms, petals, leaves, roots, veggies, etc. for juicing.
  • Transparency sheets. These can be drawn on or run through a printer. If you cannot get transparencies, objects may be used such as leaves or flowers or other material that can be flattened for contact with the paper, or you can make a waxed paper transparency (we will discuss this in class).
  • If you have them, small water vials are helpful.
  • Black and white photo paper, any size any finish, short date or expired is okay, as well as fresh of course. Film, either sheet or roll, any size. Expired is fine.
  • For making chemistry: vitamin C (ascorbic acid), washing soda (soda ash or sodium carbonate). Instant coffee.


  • Polyester resin
  • Surfboard resin
  • Artist wax
  • Spray Varnish with UV protection
