Patent ID: 8480199

Claim:
A method of printing with an inkjet printer, the method comprising: a) providing a printhead including at least a first drop ejector array and a second drop ejector array; b) providing a carriage for moving the printhead along a printing region of the inkjet printer; c) providing an ink supply that is fluidically connected to the first drop ejector array; d) providing an anti-curl solution supply that is fluidically connected to the second drop ejector array; e) providing a controller for controlling the printing operations of the printer; f) advancing a portion of recording medium into the printing region; g) determining a total amount of ink to be printed to create the image; h) identifying a type of the recording medium; i) selecting an amount of anti-curl solution to be ejected onto the recording medium, wherein the selected amount is between forty percent coverage and sixty percent coverage of the area of the recording medium if the identified type of recording medium is plain paper, and if the total amount of ink ejected by the at least first drop ejector array corresponds to an average ink coverage of between 50 percent and 100 percent of the area of the recording medium; j) moving the carriage along a first carriage scan direction while the second drop ejector array ejects drops of anti-curl solution onto the portion of recording medium that is in the printing region according to the direction of the controller; k) providing a delay time that is greater than 15 milliseconds after the second drop ejector ejects drops of anti-curl solution at a given location on the portion of recording medium before printing with the at least first drop ejector array; l) moving the carriage along a second carriage scan direction while the at least first drop ejector array ejects drops of ink in an image-wise fashion onto the given location of the portion of recording medium according to control by the controller to form a swath of image; wherein the ejection of drops of ink from the at least first drop ejector array is after the 15 millisecond delay; and m) repeating steps f) through i) to form an image swath by swath on the recording medium.
