Method for recording information or images by means of ink jet printers

The invention relates to a method for recording information or images by means of ink jet printers having at least two nozzles which are at an angle with respect to one another, the ink droplets being charged electrically and being subsequently deflected between electrodes. The aim and objective is to avoid oblique impacting on the paper, to reduce the "puddle effect" and thus to improve the half tone recording and recording of the colour image. In the method according to the invention, the ink droplets which are ejected from at least two nozzles are provided with one of two predetermined charges so that, after deflection in a homogeneous electrical field, they either fly into collection gates or move on on a flight path which is common to all of them and extends perpendicularly with respect to the recording medium. Thus, some droplets are melted before impacting on the recording medium. ...

Ink jet print head with varied nozzle spacing for producing a seamless swath of printing

An ink jet print head 10 includes an array 12 (Fig.1) of nozzles 14 (Fig.1) arranged along an axis 16. The array has a first portion 22 in which the nozzles are spaced apart along the array axis by a first pitch, and a second portion 24 in which the nozzles are spaced apart by a different second pitch. The array may have a third portion 20 (Fig.1) between the first and second portions with a third pitch different from the first and second pitches. An assembly 30 (Fig.2) may include two or more of the print heads 10, with the second portion 24 of one head overlapping with the first portion 22 of the other head. The assembly may be operated by determining a best aligned pair of nozzles (72,83,Fig.5A), disabling the nozzles (73-75,84,85) extending beyond each member of the pair, and disabling one of the pair to prevent double printing of a single dot row, before printing therewith. The assembly ensures a seamless swath of printing.

Printer ink reduction

Intercepting and processing image data for printing an image, so that the printer uses less ink (or toner) to print the image than it would if the processing was not performed. This can be achieved by reducing the number of dots printed by the printer, preferably by removing the same number of dots from each half-tone cell, but from random positions within the half-tone cell. The user can select the "grey value" via a user interface, shown. Preferably the edges of objects such as text fonts, black lines etc. are preserved. An embodiment for ink reduction during colour printing involves mapping the pixels in the image from the work space of the image data to the Hue, Luminance and Saturation (HLS) colour model, modifying the saturation or luminance of some or all of the pixels, and mapping the pixels back to the work space of the image data (Fig. 7). To preserve coloured ink, pixels can be modified to use more black ink at the expense of coloured ink. In a further embodiment, the predicted ...

Inkjet printing with uniform wear of ink ejection elements and nozzles

In one embodiment of the invention, an inkjet printer selectively energizes ink ejection elements in a scanning printhead such that the top nozzles of the printhead do not always print the first line of text in a scan. In one embodiment, this is accomplished by occasionally aligning the bottommost nozzle in the printhead with the bottom of the last full line of text to be printed during the scan. The alignment of the printhead with respect to the lines of text to be printed is varied from page to page or varied at other intervals so that the top nozzles and bottom nozzles are used about equally. This will also cause more uniform wear of the middle nozzles. The more uniform wearing of the nozzles and ink ejection elements extends the life of the printhead. In inkjet printers using a black ink printhead which has a wider printing swath than one or more color ink printheads in the same scanning carriage, a new printing technique makes use of the nozzles in the wider printhead which extend ...

The deposited fixer and overcoat then react with one another to form a protective coating over the ink so as to protect against smudging and to preserve the print quality. There is also disclosed a control method for and a programmed processor for the method as described above.
