A production process and a related device comprises a formation process comprising: contacting a first liquid material and a second liquid material with each other at a contact point in a gas atmosphere, wherein at the contact point at least one of the first liquid material and the second liquid material is provided as a liquid jet propagating in a direction, to provide at the contact point a third jet of a coalesced third material propagating in a third direction.

An image forming method is provided. The method includes the steps of (a) applying an ink to a recording medium to form an image and (b) applying a pressure to the recording medium to which the ink has been applied. The ink comprises water, an organic solvent, and a colorant. When the ink is formed into an ink film, a maximum value of logarithmic damping ratio of the ink film is 1.50 or less and a time elapsed until the logarithmic damping ratio reaches the maximum value is 3,800 seconds or less, when measured by a rigid-body pendulum test at 60° C.

An ink jet printing method includes scanning a printing medium in a scanning direction a plurality of times with an ink jet head from which inks and a treatment liquid acting to flocculate constituents of the inks are ejected. The ink jet head includes first ink nozzles filled with a first ink and arranged in a sub-scanning direction, second ink nozzles filled with a second ink having a different composition from the first ink and arranged in the sub-scanning direction, and treatment liquid nozzles filled with the treatment liquid and arranged in the sub-scanning direction. At least some of the treatment liquid nozzles are coincident in the sub-scanning direction with the first and second ink nozzles. The first ink nozzles are closest to the treatment liquid nozzles in the scanning direction, and the first ink exhibits a viscosity increase by a factor of 6.0 or less.

The present disclosure relates to a process for printing comprising the steps of selecting eight or fewer process colors from a known process ink color set, providing a color channel for the selected process colors from the known process ink color set, providing two or more spot color channels, wherein one or more of spot colors correspond to a non-selected process color of the process ink color set, applying a first ink limit and a first linearization to the one or more spot color channels to produce a color set including the non-selected process color of the known process ink color set, applying a second ink limit and a second linearization to the one or more spot color channels to produce a color set including the spot color, and optionally printing an image.

Provided herein is an inkjet dye-sublimation ink composition that is formulated to interact with an immobilizing composition such that the ink composition coagulates on the surface of an absorptive substrate, thereby substantially limiting soaking of the ink composition into the substrate. Also provided are a printing process and a printing machine, wherein the ink composition is directly printed on the substrate concomitantly with the immobilizing composition, and thereafter undergo heat-pressing to afford a dye-sublimation transfer of the dye to the substrate, thereby forming an image which is characterized by sharp and well defined edges of the dyed areas.

When a job does not exactly match the purpose of a printing profile but would benefit from some of the characteristics of a different printing profile, dynamically making the tradeoffs between the printing profiles is desirable. For example, a high-ink, large gamut profile might not be needed for a particular job, but an ink-saving profile would be excessively grainy. An intermediate profile would be recommended. Alternatively, the ink-saving profile can be adequate for everything except the skin tones in the print. Presented here are systems and methods to create a blended representation that could adopt the high-ink rules for a portion of the image, but ink-saving rules elsewhere. For example, the high-ink rules can be applied to the skin colors, but ink-saving rules can be applied in other parts of the image.

A recording method includes a step of applying a first ink to a recording medium; and a step of recording an image on the recording medium by applying a second ink so that the second ink at least partially overlaps a region to which the first ink has been applied. The first ink is an aqueous ink containing a silver particle. The second ink is an aqueous ink containing a coloring material. The recording medium has an ink receiving layer that contains a halide ion selected from the group consisting of a bromide ion and an iodide ion. The ink receiving layer has a halide ion content (mmol/m.sup.2) of 0.1 mmol/m.sup.2 or more to 0.8 mmol/m.sup.2 or less.

A pretreatment liquid for inkjet recording contains a photobase generator that produces an organic amine compound through light exposure. An inkjet recording apparatus forms an image on an image formation area of a recording medium. The inkjet recording apparatus includes a pretreatment section, a light exposure section, and a recording head. The pretreatment section ejects the pretreatment liquid for inkjet recording toward the image formation area of the recording medium. The light exposure section performs light exposure on the image formation area of the recording medium to which the pretreatment liquid for inkjet recording has been ejected. The recording head ejects an ink toward the image formation area of the recording medium subjected to the light exposure to form the image.

An image is printed by using a first, second and third ink. A surface tension difference between a first ink and a third ink is smaller than a surface tension difference between the first ink and a second ink. A first gradation value for the first ink, a second gradation value for the second ink and a third gradation value for the third ink are quantized to generate a first quantized value, a second quantized value, and a third quantized value respectively. This quantization processing is performed such that, the number of pixels for each of which the first quantized value indicates printing, a the second quantized value indicates non-printing and the third quantized value indicates non-printing is greater than the number of pixels for each of which the first quantized value indicates printing and at least the second quantized value indicates printing or the third quantized value indicates printing.
