Abstract: A printing system according to this invention includes a display, a storage section, a determination section, and a control section. The display is capable of displaying an ECO mode recommending screen which recommends a plurality of ECO modes for selection. The storage section is configured to store therein a characteristic of a printing data item unsuited for ECO mode printing. The determination section is configured to determine whether or not a printing data item is suited for the ECO mode printing. The control section causes the display section to display the ECO mode recommending screen in response to a determination made by the determination section that the printing data item is suited for the ECO mode printing and then start a printing process in response to a printing instruction given by a user.

Abstract: An image processing apparatus is connected to a print control device that controls a single printer, the apparatus includes a first generating unit that generates a first corrected image by adding an adjustment image to one of edges in the first direction of the first image such that a length in the first direction is equal to an integral multiple of a predetermined boundary size, a second generating unit that generates a second corrected image by adding the adjustment image to at least one of both edges in the first direction of the second image such that the length in the first direction is equal to an integer multiple of the boundary size, and a transmission unit that transmits the first corrected image and the second corrected image to the print control device.

Abstract: An embodiment has: weighting interpolation section for obtaining a pixel value for a missing pixel by a one-dimensional weighting interpolating method, using pixels in the vicinity of the missing pixel as reference pixels, and for generating a primarily interpolated image signal including the interpolated pixel value in place; frequency decomposition section for decomposing the primarily interpolated image signal into frequency components; halftone dot extraction sections for obtaining a halftone dot degree indicating a degree for the vicinity of the missing pixel to be in the halftone dot region, by using higher ones of these frequency components; correction value calculation section for calculating a correction value for the missing pixel, by using lower ones of these frequency components; and correction section for correcting the pixel value of the missing pixel in the primarily interpolated image signal using the correction value depending on the halftone dot degree.

Abstract: A method to generate random and density controllable dot patterns on an optical device includes steps of dividing a 2D domain into multiple cell units; determining dot density in each cell; creating at random initial location of dots in each cell; solving the force operation cut radius of the dot; setting up a residual force; solving the force control parameter in the cell; performing the force operation for the cell; making the dots in the cell to achieve balanced positions after repeated operation; completing the generation of a dot pattern within a 2D domain; and transferring the dot pattern to the optical device by a transfer printing equipment.
