Formated printing head

FIELD: printing industry.

SUBSTANCE: suggested formated printing head includes a printing head matrix in a moulded article having a channel therein through which the fluid can pass directly to the rear part of the matrix. The front of the matrix is exposed outside the moulded article surrounding the matrix, the front faces of the moulded article and the matrix forming one continuous flat surface. Between the terminals in the front of the matrix and the contacts, electrical connections are made to connect to circuits external to the printhead.

EFFECT: proposed head, due to the low-profile protective coating, allows to simplify its maintenance.

SUBSTANCE: claimed invention relates to device of image formation and printing production. Device of image formation contains head of liquid discharge, in which nozzles for liquid drops discharge are arranged close to each other, unit for formation of oscillating signal of excitation, forming in range of one cycle of excitation first oscillating signal of excitation, which contains signal of excitation for discharge of liquid drop volume, which is used for image formation, and second oscillating signal of excitation, which contains excitation signal for liquid drop volume discharge, smaller than minimal discharge drop volume, used for image formation. Unit of head control impels head of liquid discharge to discharge volume of drop of liquid, used for image formation, according with first oscillating signal of excitation for area, where image is formed, and to discharge liquid drop volume, smaller than minimal discharged drop volume in accordance with second oscillating signal of excitation for area, where picture is not formed.

EFFECT: creation of improved device of image formation, in which shortcomings of previous level of technology are eliminated.

SUBSTANCE: invention relates to ink glazes for digital printing, method of their manufacturing and the use of the noted glaze composition for the functional and/or decorative coating of ceramic and/or metallic material. Ink glazes for digital printing include a solid component obtained from organic and/or inorganic materials and dispersed in a polar and/or the aqueous liquid component. The solid component, where the particulates size is less than 40 microns, is from 10 to 70% of the total ink weight, and comprises: at least a charge material (flux), frit or ceramic raw material and the deposition preventing agent. The liquid component includes: water of at least 5% of the total ink weight, and at least 2% of one or more nonaqueous polar solvents of the total weight and additives.

EFFECT: invention provides producing ink glazes for highly-productive digital printing.
