Abstract:
A printer and a method of processing an image (1) to be printed with a printer which has a printing unit arranged to produce a printout from image-representing print data of the image, and a processing unit for processing image-representing input data of the image so as to generate the image-representing print data. The processing unit is arranged for separating the image into a line detail sub-image (20) containing edge and line details, and an area detail sub-image (25) containing area details, performing a first printing mode processing pipeline on the line detail sub-image and performing a second, different printing mode processing pipeline on the area detail sub- image, and generating multi-layer print mask data, wherein at least one print mask data layer is usable to print the line detail sub-image in at least one line detail print pass, and the remaining, i.e. at least one, of the print mask data layers being used to print the area detail sub-image in at least one area detail print pass to produce an image (50) which has optimized image quality.
Abstract:
Read image data is segmented into a plurality of regions in accordance with the attribute of the image data. A region to be printed using a transparent toner is set in accordance with the attributes of the plurality of segmented regions. A preview of the image represented by the image data is displayed, in which the region set to be printed using the transparent toner is distinguished from the remaining regions. An instruction to change the region to be printed using the transparent toner is accepted based on the displayed preview. Print data for the transparent toner to print, using the transparent toner, a region determined based on the change instruction to be printed using the transparent toner is generated.
Abstract:
An image outputting device capable of printing or displaying/outputting an image and text data automatically and efficiently off-line to a digital copying machine, a printer, a facsimile or a liquid crystal projector. Image discriminating means discriminates whether the data to be printed in a data file, as read out of a memory card by a memory card controller (88), is color or black-and-white image data. If the result of discrimination indicates color image data, print confirming means is provided for the user to confirm whether or not black-and-white data converted from the color image data by color/black-and-white conversion means (90) is to be printed/outputted by black-and-white image forming means.
Abstract:
Bidirectional error diffusion halftoning of data. Pixels are halftoned in one serpentine direction, and pixels are halftoned in an opposite serpentine direction.
Abstract:
There is described a method of checking producibility of a composite security design of a security document, in particular of a composite banknote design, on a line of production equipment, the composite security design being the product of a combination of multiple sets of design features that are to be provided on a substrate as a result of a plurality of successive production operations carried out by means of the line of production equipment. The method comprises the steps of (a) providing digital design data representative of the composite security design of the security document, (b) modelizing, in a computer environment, the line of production equipment by means of which the composite security design is intended to be produced, (c) performing a computer simulation of production results of the plurality of successive production operations on the basis of the digital design data and the modelized line of production equipment, and (d) evaluating the computer simulated production results and determining, on the basis of these computer simulated production results, whether the composite security design can be produced on the line of production equipment.
Abstract:
An evaluation apparatus includes an image reproduction section, which obtains a reproduction image by reproducing an original image with a plurality of color elements visually mixed for defining colors, and which obtains a plurality of reproduction images respectively corresponding to twelve types of color element groups having different types of color elements and/or different numbers of color elements from one another. The apparatus also includes a calculation section which calculates a level of a difference between colors of each of the plurality of reproduction images and colors of the original image; and a display section which displays the level of the difference calculated by the difference calculation section.
Abstract:
A method and a device are disclosed for luminous printing of an original image using fluorescent ink or other fluorescent display pigments. In some embodiments, the original image is separated into multiple layers, including at least a brightness layer and an inverse brightness (or darkness) layer, by applying extracted brightness data and inverse brightness data, to the original image, respectively. Each of the layers is associated with a set of corresponding printing channels. The sets of printing channels are applied by a printing device to print the original image on a print medium, such as paper, mylar, fabric, and other print surfaces. Multiple visual effects may be realized using the aforementioned process, including fluorescent images that are only visible under UV (Ultra Violet) or black light, images with high-fidelity colors under daylight and dark conditions, and shadow effects such as depth illusion.
