In a method and an apparatus for forming on a substrate () a pattern of a material, a material layer is provided on an intermediate carrier () and an adhesive layer is provided on the material layer, wherein at least one of the material layer or the adhesive layer comprises a pattern corresponding to the pattern to be formed on the substrate (). The material is transferred to the substrate () with the adhesive fixing the material to a surface () of the substrate ().

Method and apparatus for forming on a substrate a pattern of a material

An example method of printing images in an electrophotographic printer is provided. The method includes developing a first image on a first portion of an intermediate transfer member by receiving a first sequence of color separations from a photo imaging member, and developing a second image on a second portion of the intermediate transfer member by receiving a second sequence of color separations from the photo imaging member. A voltage is applied to the intermediate transfer member during receipt of each color separation from the photo imaging member. During development of the second image at least one null separation is inserted into the second sequence of color separations. During a period for the null separation, a voltage applied to the intermediate transfer member is reduced and the first image is transferred to a conductive substrate.

Print sequence in an electrophotographic printer

An embossing apparatus includes an embossing die that includes a printed relief pattern made up of multiple layers of a deposited material. A resilient surface presses media against the embossing die such that embossed features corresponding to the embossing die are formed in the media. A method for embossing media includes forming an embossing die by depositing multiple layers of ink on a impression layer to form a relief pattern and pressing media against the embossing die to transfer the relief image to the media.

Embossing with printed relief pattern

There is provided a method and apparatus for preparing a print substrate. A surface resistivity of a print substrate comprising a conductive layer is determined. The determined surface resistivity is compared to a print range having a lower threshold value for the surface resistivity of the print substrate and an upper threshold value for the surface resistivity of the print substrate. If the determined resistivity of the print substrate is outside the print range, a surface modification is selected to adjust the determined surface resistivity of the print substrate to fall within the print range. The selected surface modification is applied to the top layer of the print substrate.

Print substrate surface modification

According to one example, there is provided a visual security feature. The visual security feature comprises a security feature printed on a media. The security feature includes a security code printed on the media, and a holographic image is embossed on the printed security feature.

Visual security feature

Herein is disclosed an electrostatic ink composition. In some examples, the electrostatic ink compositions comprise: a carrier liquid; a resin; and a phosphorescent pigment.

Electrostatic ink compositions

A method for forming on a substrate () a pattern of a material, the method comprising: providing (S) a material layer (); providing (S, S) an adhesive layer (), wherein at least one of the material layer () or the adhesive layer () comprises a pattern corresponding to the pattern to be formed on the substrate (); and transferring (S) the material to the substrate () with the adhesive fixing the material to a surface () of the substrate (). This solves the problem of forming on a substrate a pattern of a material that, in general, cannot be applied to the substrate directly due to the fact that the material cannot be printed and/or has no or reduced adherence properties with respect to the substrate.

An example system includes a color engine to separate an image into a plurality of color components. The system also includes a halftone engine to generate a plurality of halftone images based on the plurality of color components and a plurality of halftone screens. For each halftone screen, the halftone cell centers for that halftone screen occur at regular or semi-regular distances relative to a dot pitch. The plurality of halftone screens forms a high frequency moire pattern when the halftone screens are overlaid on each other. Each of the halftone screens have a granularity metric less than a threshold.

Halftone screens

Herein is disclosed an electrostatic ink composition. In some examples, the electrostatic ink compositions comprise: a carrier liquid; a first resin; and a fluorescent pigment. The fluorescent pigment comprising a fluorescent dye and a second resin matrix, wherein the second resin is selected from the group comprising polyamide resins, polyvinylchlorides, polyolefin resins, polystyrenes, acrylonitrile-butadiene-styrene resins, polycarbonates, poly acrylic and methacrylic acid resins, polyethylene terephthalates, polyamide resins, polyurethanes, epoxy resins, silicone resins, polyester resins, alkyd resins, acrylonitrile polymers, polyesteramides or combinations thereof.

In an example implementation, a method of rosette-free printing includes, in a printing device whose color plane misregistration is less than 15 percent of a screen ruling of a halftone screen, printing multiple color planes of a multicolor image using the halftone screen.

Rosette-free printing

A halftone comprises a first halftone screen and a second halftone screen. The first halftone screen comprises a first plurality of amplitude modulated dots arranged according to a first plurality of rows, the first plurality of rows being orientated according to a first direction and comprising a first dot spacing. The second halftone screen comprises a second plurality of amplitude modulated dots arranged according to a second plurality of rows, the second plurality of row being orientated in a second direction and comprising a second dot spacing. The first direction and the second direction define an angle of 45 degrees or less and a ratio of the second dot spacing to the first dot spacing is less than one.

Generating halftones

In an example implementation, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to receive a list of print jobs, and calculate a preparation time and a printing time for each job in the list. The instructions further cause the processor to generate an ordered print job queue that minimizes printing press downtime by maximizing an amount of the preparation time fulfilled during the printing time.

Ordering jobs in a print queue based on preparation and print times

According to one example, there is provided a method of generating a security feature that encodes data. The method comprises obtaining an n-bit code of data to encode, generating an arrangement of dots, designating a first portion of the dots as reference dots and a second portion of the dots as encoding dots, and moving a group of the designated encoding dots by a predetermined direction in a predetermined amount to encode the n-bit code of data.
