To make it possible to print a smooth image without color irregularity at a high speed by a printing apparatus using a color ink-jet head provided with plural arrays of ink ejection openings side by side in the direction of the main scanning corresponding to different color inks, moving this head to scan reciprocally, and also adopting a multi-pass printing method for divided printing on a certain area by scanning at plural times with the color ink-jet head. In the multi-pass printing using the ...

Deterioration in image quality is caused by deviation in dot forming positions between rasters in the case of carrying out printing of adjoining two rasters. The rasters are printed by two columns of ejection openings array disposed on an ink-jet head. To suppress image quailty deterioration, the two columns of ejection openings are shifted from each other by a half of a pitch at which the ejection openings are arranged in the column. When allocating input image data quantized into multi-valued ...

A printing method is for printing per line by driving a printing head to travel in the main scanning direction. This printing head is provided with a plurality of printing elements arranged in the direction almost but not exactly perpendicular to the main scanning direction. In this method, when the printing head is driven to travel in a speed faster or slower than the standard speed for the usual printing operation, the number of printing elements of the printing head to be used for printing is...

A printing apparatus includes a printing section for performing a printing operation on a print medium and a sheet transporting section having a pair of opposite rollers that transport a print medium by rotating while sandwiching the print sheet therebetween. Further, a storage section stores positional information representative of the nip position at which an end of a print medium P is sandwiched between the pair of rollers.

A printing method of playing out piled sheets of paper one by one, feeding the played-out sheet of paper to the position of a platen, and printing the sheet of paper, the printing method includes the steps of: (a) feeding the sheet of paper played out from the piled position thereof at a first speed until the sheet of paper approaches a platen which is stopping; (b) feeding the sheet of paper at a second speed lower than the first speed until a required short time passes from a time when the she...

A third reference position on an eccentric cam positions a thermal head touching a follower roller at a retreated position separated from a printing position when printing is idled, and a second reference position of a middle-sized radius on an eccentric cam applies a thermal head touching a follower roller with a pressure of approximately 39 N to a card therebetween interposed by thermal transfer film, when in a direct transfer execution state. Also, when in an indirect transfer execution state...

This invention provides a low-cost, economical printing apparatus and printing system. For example, characteristic information of a printhead which is described, printed, adhered, or formed on a printhead or its accessory (e.g., a packaging paper box) in a format identifiable to human or an electronic device is man-machine-interactively inputted to a host or electronically inputted to the host by a barcode reader or the like. The printing apparatus discriminates whether or not a command sent fro...

A process and a plant for applying of one or more compounds, such as inks or coatings, to a substrate. In each station of the plant at least one compound is applied by a process that requires applying an essentially liquid mixture containing the compound to be applied to a transfer medium, heating the tranfer medium to obtain coagulation of the portion of the mixture which is in contact with the transfer medium, and placing the transfer placed in contact with the substrate so that the coagulated...

In a printing apparatus of the present invention, image data divided into a plurality of pages and supplied from an application program are printed on a roll of machine glazed paper without any margins set between adjoining pages. This arrangement enables a large image to be printed on a large-sized printing medium, such as a banner. A printer driver in the printing apparatus sets feeding amounts of sub-scan according to a selected printing mode. In the case where a standard printing mode is sel...

There are provided a printing paper and a printer for eliminating margins of photographs and the like by using a simple structure. After printing processing has been carried out on a sheet of a printing material, the sheet is detached from the printing material along a cut line. Namely, a print having no margins is formed. Therefore, cutting position controlling mechanisms and paper cutting mechanisms as used in conventional printers are not necessary, and the structure of the printer is thereby...
