    摘要： In the field of printing technology, non impact printing methods such as inkjet printing may be used to deposit an ink composition onto print media to form an image. An ink composition typically comprises a colorant material and a vehicle, such as an aqueous solution, for delivering the colorant material to the print media. A wide range of such ink compositions is known in the industry. It is also known to use various pre-treatment compositions in combination with ink compositions in order to enhance the quality of a final image. Pre-treatment compositions are often substantially colorless liquid compositions that interact with elements of the ink composition to fix colorant to the print media. Pre-treatment compositions may help to improve image quality for example by reducing image bleeding, edge roughness and other image quality issues.

    摘要： Examples associated with printer configuration are disclosed. One example includes printing, using a printer, a first portion of a test patch in a first print direction. A second portion of the test patch is printed in a second print direction. The second portion is printed at a first offset from the first portion. A first portion of a second test patch is printed in the first print direction, and a second portion of the second test patch is printed in the second print direction at a second offset from the first portion of the second test patch. The printer is configured to print in the second print direction using one of the first offset and the second offset based on a selection between the first test patch and the second test patch.

    摘要： A printer control section arranged to control a printhead, is operable to cause the printhead to: perform a plurality of passes over a swath of a print medium, the plurality of passes including first and second treatment passes; apply treatment to the print medium in each of the treatment passes, the treatment in each treatment pass being applied according to a respective treatment mask, wherein each treatment mask indicates a corresponding set of pixels to which the treatment may be applied in a pass to which the treatment mask is applied, the treatment mask having a weight indicative of the proportion of pixels in the corresponding set of pixels, and the treatment masks of the first and second passes are such that a weight of the first treatment mask is different from a weight of the second treatment mask.

    摘要： According to one example, there is provided a method of controlling a printing system. The method comprises: obtaining a print job to print on a substrate; obtaining a value of a factor material to an undesirable condition occurring; determining a quantity of printing fluid to be deposited on a substrate when printing a portion of the print job; determining, based on the obtained value and the determined quantity of printing fluid to be deposited, whether the undesirable condition is likely to occur whilst printing the portion of the print job; and temporarily reducing the throughput of the printing system whilst printing the portion of the print job where it is determined that the undesirable condition is likely to occur whilst printing the portion of the print job.

    摘要： An example printing apparatus is described comprising a wiping element before the print zone, for slipping in contact with a print medium and wiping a printing surface of the print medium. An implementation of a wiping roller for wiping the printing surface of a print medium may comprise a rigid core, a layer of elastic material and a driving pinion. An example method for printing is also described, comprising spreading over a larger print medium area, by wiping, amounts of a substance that may migrate through a print medium and that is present on the printing surface of a print medium, before printing on the print medium.

    摘要： An example printing device composing a first printhead and a second printhead is described. In some examples the example printing device comprises a controller. The example printing device is to operate in a first operating mode in which the first printhead is to dispense a first printing substance, the first printing substance to transfer color via a first colorant transfer mechanism, and to operate in a second operating mode in which the second printhead is to dispense a second printing substance, the second printing substance to transfer via a second colorant transfer mechanism different to the first colorant transfer mechanism. An example controller is to cause the example printing device to operate in a selected one of the first and second operating modes.
