The K Control Coater (Model 101, from RK Printcoat Instruments Ltd.,) is used for application of  coatings, paints, and inks to produce uniform film thickness with highly accurate and repeatable coatings. A range of Mayer Rods (or Meter bars) can be chosen to control the wet film thickness from 4 to 120μm. at controlled speed of the coater. A special purpose vacuum bed is available to hold the materials perfectly flat especially for thin and flexible substrates.
