1. A method of making a rotatable mask, the method comprising:

  • a) depositing a first polymer precursor liquid on a first surface of a first master mask, wherein the first surface of the first master mask includes a pattern;

    b) curing the first polymer precursor liquid to create a first cured polymer, wherein the first cured polymer and the first master mask together form a laminate;

    c) configuring a first end of the laminate to have a strip of the first cured polymer missing and a second end of the laminate to have a strip of the first master mask missing;

    d) rolling the laminate inside of a first casting component;

    e) depositing a second polymer precursor liquid in a gap of the rolled laminate that corresponds to the strip of the first cured polymer;

    f) curing the second polymer precursor liquid to form a second cured polymer, whereby the first cured polymer and the second cured polymer together form a compliant layer for the rotatable mask, whereby the outer surface of the compliant layer includes a pattern that corresponds to the pattern of the first master mask.
