Übersetzung für "Rasterdruck" in Englisch

Paintings: three by Edward Steichen (reproduced in three-color half-tones).

The pictorial decorations can be printed over the whole surface by halftone or line processes.

A conventional printing process, preferably, screen printing, is used for this.

No smooth colour gradients possible (halftone printing is possible)

The conventional four spectrum colors of cyan, magenta, yellow and black form the basis for the raster printing.

Plates with pronounced cupping and inadequate depths between the image dots tend, logically, to form ink bridges in high-quality halftone printing.

Light can be decoupled here through a printed grid pattern or through a roughened surface, for example.

Examples include screen printing, stenciling, halftone printing, doctor blade coating, or spraying.

The subsequent coating of the nonmagnetic base with the magnetic dispersion is carried out in accordance with the state of the art, for example by means of reverse roll coaters, halftone printing or extruder casters.

Another advantage consists in that a uniform background brightness is made possible in the blocked areas of the LCD by known measures, such as e.g., the arrangement of scattering foils and fluorescent plates, screen print and the like, and in that a uniform transmission of light in the controlled surface area segments of the LCD is achieved.

Therefore, the foil of such a configuration, between the diffraction layer and the backing foil, only has a grid-like design defined by the lacquer forming the signing layer, so that the diffraction layer can still be seen through the spaces defined by the grid-like pattern.

To produce magnetic tapes, dispersions containing the binder-containing magnetic particles are applied to flexible substrate by screen printing, extrusion coating methods and similar coating techniques.

It is also advantageous, especially with use for medical products, if the pressure-sensitive hotmelt adhesive composition is applied partially to the backing material, for example by halftone printing, thermal screen printing or intaglio printing, because backing materials which have been self-adhesively treated in a continuous applied line induce, on application, mechanical irritations of the skin.

Preferably in addition the hotmelt adhesive composition is applied to the backing material by halftone printing, thermal screen printing or intaglio printing and moreover, in a particularly preferred embodiment, is applied in the form of polygeometric domes.

It is a further aim of the invention to design the process and the arrangement such that a finely graded offset-like matrix print is possible.

It is also advantageous, especially for use in medical products, if the foamed adhesive composition is applied partially to the backing material, for example by halftone printing, thermal screen printing, thermal flexographic printing or intaglio printing, because backing materials which have been self-adhesively treated in a continuous applied line may under adverse circumstances induce mechanical skin irritations when applied.

It is also advantageous, especially for use in connection with medical products, if the hotmelt adhesive composition is applied partially to the backing material, by means for example of halftone printing, thermal screen printing, thermal flexographic printing or intaglio printing, because backing materials which have been adhesively treated in a continuous applied line may easily induce mechanical skin irritations when applied.

Matching the transmissions of the various regions can be achieved, for example, by a neutral overprint or half-tone overprint of different density, and thus of differing transmission.

It is also advantageous, especially with use for medical products, if the hotmelt adhesive composition is applied partially to the backing material, for example by means of halftone printing, thermal screen printing or intaglio printing, because backing materials which have been self-adhesively treated in a continuous applied line may, on application, induce mechanical irritations of the skin.

Improved tonal value transfer characteristics in multicolor halftone printing are therefore also achieved in indirect printing processes (dry offset), such as tube, cup and can printing.

By specific control and formation of the laser beam, it is possible to adapt the quality of the letterpress relief to the letterpress-specific printing requirements for improving the printing characteristic in halftone printing.

The color palette produced according to the method and system of the invention represents an assignment of color locations of a color space with mathematical basis to remission curves which are realized by a given coloring process (such as color mixing or laser printing), with a given number of base colors and a given substrate.

The data carrier of claim 9, wherein said first colored non-metallic layer is a black halftone print exhibiting a nonuniform intensity and contacting a different colored second layer.

The following exemplary recipe systems and the associated mathematical models are described in the literature and can be used for the calculation of the remission curves according to the present disclosure. It is possible to disinguish these systems between systems that are based on color mixing and systems based on raster printing:

The conclusion may be drawn from the investigations that, of the grids for reproduction with screen printing, hexagonal grids are superior to quadratic grids, regardless of whether they are produced with ink printing, wire matrix printing, or in some other way.

The different forms of apparatus described above are suitable not only for screen printing but also for those printing processes which work with screened copies.
