Class Policies & Information:

Open Lab: This class includes access to the studio during Open Lab hours. Open Lab is exclusively for students who are currently enrolled in the program. You are allowed to attend one Open Lab session per week, totaling 3 hours during the duration of your class. You may only attend the Open Lab session for the class in which you are registered. This time is intended for independent work on your class project. While studio staff will be present, they are there to ensure you are using the tools safely, not to provide instruction.

Class Make-Up: Our studios are full with adult and youth classes 7 days a week, 48 weeks a year. Typically, every class is full, which means there is simply no space for students to make up classes. If we cancel an entire class due to weather or other emergencies, we can not guarantee we will be able to schedule a make-up class. Individuals who miss a class will not be able to make it up. Please read the Frequently Asked Questions for more information about missed classes.

Studio Clean Up: Clean-up is critical! Please help our hardworking staff and volunteers by beginning clean-up 30 minutes before the end of class, helping out with common areas, and leaving class on time.

Ages: 16+ 

All supplies and materials will be provided.

We will be using a variety of methods to apply ink and print from a plexiglass plate, such as stencils, strategic taping, and pressing objects directly into the ink to produce a unique print. 

Students will learn the basics of monotype printmaking using plexiglass plates, applying ink and incorporating found objects.

This class is ideal for those who have limited experience with printmaking. A monotype is a print that typically starts with a blank surface and results in a one-of-a-kind print. 

There will be a short instructor demo and hands-on assistance each week. Students will try introductory techniques, including making a collagraph plate, mixing and applying ink, and making a print using the press. Come have some fun in our new printmaking studio!
