FIELD: printing.
SUBSTANCE: head for screen printing and application method of printing layers on processed article through aperture in screen mesh, wherein head comprises main body support for attachment to screen printing device, support element, containing elongated element, printing blade attached to support, which is blade scraper and vibration unit connecting element support with body support for excitation of oscillations and support element and, therefore, printing blade attached to it. At that, vibration unit drives oscillations of support element on one or more frequency in range approximately from 20 to 50 kHz and with displacement of support element approximately at least for 0.4 mcm, so that said head for printing provides transfer efficiency equal to at least 75 %, through aperture, having ratio of areas of 0.4.
EFFECT: higher efficiency of transfer.
