    Abstract: There is disclosed a non-transitory machine-readable medium encoded with instructions executable by a processor and comprising instructions to: control print apparatus to print a test pattern 11 on a test region of a print medium 4; receive test data relating to the test pattern 11 printed on the print medium 4 from a sensor 8; analyse the test data with reference to baseline data to determine if the test pattern 11 satisfies a print quality criterion; output an instruction to operate the print apparatus in a first mode, in which a pre-printing treatment is not applied to the print medium, in response to determining that the test pattern 11 satisfies the print quality criterion, the pre-printing treatment comprising wiping a printing surface of the print medium with a wiper element 10, 20; and output an instruction to operate the print apparatus in a second mode, in which the pre-printing treatment is applied to the print medium 4, in response to determining that the test pattern 11 satisfies the print quality criterion.

    Abstract: Herein is described a method involving a drop detector. The method may comprise: ejecting ink drops from the nozzles on a printhead toward a drop detector. A drop characteristic may then be determined from the drop detector for each ink-jet nozzle. Drop characteristics for the nozzles across the printhead may be collated into a data set, and compared with a predetermined data set for a printhead having predetermined print behaviour to determine if and how the data sets differ in terms of the pattern of drop characteristics across the printheads. If the data sets differ, a recovery strategy may be selected based how the data sets differ in terms of the pattern of drop characteristics across the printheads. A system and computer readable medium are also described herein.

    Abstract: 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.
