摘要:
Disclosed are a threshold value data setting device, method, and program and an image forming system capable of, even if the number of types of printing devices and printing materials is enormous, simply and easily determining threshold value data suitable for any combination thereof. A change in dot shape occurring in an image forming process from the creation of a binary image signal 46 to the formation of an image is acquired as response characteristics data 112 in a spatial frequency domain. The response characteristics data 112 is applied to create a simulated image signal in which the change in dot shape is reproduced in a simulated manner. Threshold value data 44 to be set is determined from among threshold value candidates by a comparison and/or evaluation based on quantitative values calculated by executing predetermined evaluation processing for the simulated image signal.

A plate printing method 100 includes a repetition of a first step (S1) of depositing ink 2 on a printing master 10 to form a predetermined print pattern 1 on it, a second step (S2) of transferring the ink 2 to a blanket 20, a third step (S3) of pressing the blanket 20 against a surface 30 to be printed, a fourth step (S5) of pressing the blanket 20 against a cleaning surface 40, a fifth step (S5) of pressing the blanket 20 against an absorbent 50, a sixth step (S6) of blowing air to the blanket 20, and a seventh step (S7) of pressing the blanket 20 against a dry surface 70. In the first step, the blanket 20 with a proper amount of water or solvent impregnated into it is pressed against the printing master 10.

A method of transferring a material to a substrate includes selectively depositing the material on a surface of an applicator and contacting the surface of the applicator to the substrate. The material can form a pattern on the surface of the applicator. The pattern can be preserved when the material is transferred to the substrate. The material can be deposited on the applicator by ink jet printing.

The invention provides a process to deliver an elastomeric composition to a substrate. The elastomeric composition is cooled. The cooling also results in substantially complete transfer of the elastomeric composition from the pattern roll to the substrate with a resulting reduction in elastomer degradation.
摘要:
A method for printing and decorating packaging materials, such as paper, paper board and various flexible polymer films by electron beam exposure ofplural layers of curable inks and coatings which do not substantially change viscosity during the printing process. The inks and coating are essentially free of volatile components such as organic solvents, inorganic solvents, water and low molecular weight fractions before, during and after exposure to electron beam irradiation. The method involves applying multiple layers of ink and an optional coating onto a substrate. The ink is an admixture of a colorant, and an unsaturated component such that the inks have a maximum of 10% volatile components. Thereafter these layers are simultaneously exposed with electron beam radiation to cause the ethylenically unsaturated components to polymerize or crosslink such that they become dried.
摘要:
A water-soluble substrate, and more particularly a water-soluble substrate that is resistant to dissolution, and methods of making the same are disclosed. The water-soluble substrate has a first and second surface. Water-insoluble particles are applied to and partially embedded in at least one of said first and second surfaces, thereby forming protruberances on said first and/or second surface. The protruberances have an average height of from 10 nanometer to 100 micrometer, and the average distance between adjacent peaks of said protruberances is from 10 nanometer to 200 micrometer. Articles, such as pouches, made from the water-soluble substrate, are also disclosed herein.

Disclosed is a process for forming a patterned fluoropolymer film on a substrate by raised relief printing a fluoropolymer solution with a patterned raised relief printing plate, and drying the solvent from the solution to form the patterned fluoropolymer film. Such fluoropolymer films are useful as antireflective or hydrophobic layers on substrates used in optical displays.
