PROBLEM TO BE SOLVED: To provide an apparatus capable of controlling a printing process and thus a printing result at an original position, directly examining the quality of a polymer layer under the printing process, and correcting it without any alterations under certain circumstances. SOLUTION: An apparatus for optical measurement has a radiation source and a radiation detector mutually arranged so that the radiation source, under operating conditions, irradiates a droplet of a polymer solution or a polymer dispersion liquid, and so that the radiation detector receives radiation reemitted from the droplet and/or radiation transmitted through the droplet. This apparatus is so configured that, at a time when the droplet newly becomes printable under the printing process, a measuring process is carried out such that a boundary surface does not remain between the droplet and the polymer quantity printed afterward.
