る。2. Description of the Related Art When printing on a screen printing machine, it is desirable to move a squeegee while the mask and a plate to be printed such as a printed board are flat. However, when a component is mounted on one side in the case of a printed circuit board, for example, a slight warp occurs on the surface on which the component is mounted. In some cases, printing is performed again on the surface opposite to the surface on which the components of the printed circuit board are mounted in such a state. In such a case, since the printed board is warped, the application amount of the printing agent by the squeegee is not uniform. Therefore, printing unevenness occurs.
