Article with bent patterns formed from aligned pigment flakes

FIELD: printing.

SUBSTANCE: in a printed article, pigment flakes are magnetically aligned so as to form curved patterns in a plurality of cross-sections normal a continuous imaginary line, wherein radii of curved patterns increase along imaginary line from first point to second point.

EFFECT: when light is incident upon aligned pigment flakes from a light source, light reflected from aligned pattern forms a bright image which appears to gradually change its shape and move from one side of continuous imaginary line to another side of continuous imaginary line when substrate is tilted with respect to light source.

SUBSTANCE: agent is stored in printing unit. Before applying the agent is maintained at operational temperature, which keeps it in liquid state, while contained liquid crystal components are in mez-amorphous state. Nematogene and/or chiral-nematogene liquid crystal components are homogenised in stirring apparatus prior to application. After crystallisation homogenised agent is milled to fine-crystal bulk and melt in chamber for paint.

EFFECT: simple and efficient method of liquid crystals application on trays.

SUBSTANCE: invention relates to jet digital printing. Proposed is a jet digital printing system containing an external applicator to apply a multicomponent multifunctional wetting solution onto the surface of an image-forming plate. Plate is exposed while forming an image using a high-power laser in order to remove basic components of the wetting solution on selective sections of the plate in compliance with the digital image data along with preservation of a layer of auxiliary components on the said selective sections. Then the plate is coloured with a paint applicable for printing. Paint is engaged with the selective sections, from which the main components have been removed, and a colourful image is formed. Colourful image is transferred at the stage of transfer, herewith the auxiliary components provide efficient transfer of the paint onto a carrier with reduction of the image quality defects. Multicomponent wetting solution contains basic components, which repel the paint, and auxiliary components, which act as a release agent.

EFFECT: proposed is a jet digital printing system.
