1188 results about "Digital printing" patented technology

Digital printing refers to methods of printing from a digital-based image directly to a variety of media. It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume laser or inkjet printers. Digital printing has a higher cost per page than more traditional offset printing methods, but this price is usually offset by avoiding the cost of all the technical steps required to make printing plates. It also allows for on-demand printing, short turnaround time, and even a modification of the image (variable data) used for each impression. The savings in labor and the ever-increasing capability of digital presses means that digital printing is reaching the point where it can match or supersede offset printing technology's ability to produce larger print runs of several thousand sheets at a low price.

Digitally printed products and process

A process for manufacturing three-dimensionally shaped polymeric sheets and laminates with color-matched digitally printed full color ink jet images. A flexible thermoformable polymeric baseweb is placed in an ink jet printer and a solvent-based (non-aqueous) digital printing ink is applied directly to the baseweb, in the absence of an ink receptive layer on the baseweb, to form a decorative pattern in multiple colors in a single pass through the printer. The finished product can be thermoformed or injection molded to a three-dimensional shape. A protective topcoat can be laminated to the digitally printed sheet prior to the thermoforming and/or injection molding step. A process for making color-matched products comprises producing a software-driven image of a pattern on a screen representing a standard color print pattern; evaluating and adjusting the standard displayed on the screen using software-driven image related adjustments for hue, contrast, lightness/darkness, etc.; producing a test print by applying a decorative pattern to the baseweb by a digital ink jet printer and making an optional software-driven image-related adjustment in the standard to color match the standard to the test print image; and when the adjusted standard image displayed on the screen is acceptable, passing an image-related output to the digital ink jet printer for printing a decorative print color-matched to the accepted onscreen standard.

Anti-counterfeiting printing method by using invisible two-dimensional codes

The invention relates to an anti-counterfeiting printing method by using invisible two-dimensional codes. The anti-counterfeiting printing method is characterized in that at least four printing layers for printing are adopted, and comprises the following steps of: firstly, providing a digital serial number and splitting the serial number into three fields of which information is assigned to three groups of two-dimensional codes; secondly, printing one group of two-dimensional codes on a first layer by using aqueous ink black materials; thirdly, overprinting a grey isolating layer on the first two-dimensional code layer by using infrared non-absorbent materials to form a second layer; fourthly, overprinting a second group of two-dimensional codes on the second layer of the grey isolating layer by using the infrared non-absorbent materials to form a third layer; and finally, overprinting a third group of two-dimensional codes on the third two-dimensional code layer by using ultraviolet absorption materials to form a fourth layer. The method has the advantages of eliminating the possibility of imitation by scanning the two-dimensional codes and achieving relatively higher use value because the overprinting is performed in the same area in an offset printing and digital jet printing way and the upper printing layer covers the lower layer naturally.

Clothes making method based on three-dimensional to two-dimensional clothes pattern seamless mapping

The invention discloses a clothes making method based on three-dimensional to two-dimensional clothes pattern seamless mapping. The clothes making method based on the three-dimensional to two-dimensional clothes pattern seamless mapping comprises the following steps: constructing a three-dimensional clothes model, and establishing a mapping relationship between the three-dimensional clothes model and a two-dimensional sample plate mesh model; designing a clothes pattern on the surface of the three-dimensional clothes model; calculating a pattern on the seam allowance of a two-dimensional sample plate; and carrying out digital printing, cutting and sewing of the two-dimensional sample plate to make real clothes. According to the clothes making method based on the three-dimensional to two-dimensional clothes pattern seamless mapping, the problems that registration and grid matching are complex, and seamless splitting can not be realized since the pattern continuity of the clothes is damaged in a conventional clothes making process at present are solved, the pattern of the clothes is more beautiful and intact when people wear the clothes, cloth is saved, and time and cost for registration and grid matching in the clothes making process are respectively shortened and reduced. The clothes making method based on the three-dimensional to two-dimensional clothes pattern seamless mapping has the advantages of specific algorithm, friendly interface and robust result.
