Method for printing on locally distorable mediums
View Patent ↗Methods for operating a printing system are provided. In one method, an inkjet image is printed on a receiver using a hydrophilic ink and an image of the receiver is captured after predetermined period of absorption. Local areas of the image of the inkjet print that have reached a threshold level of non-uniform distortion and where additional ink remains for absorption are identified. A distortion estimate is determined for distortion of the receiver at a time when a second image will be printed on the receiver based upon information from the identified areas. A second print image is printed based on the distortion estimate; and, the second image is printed.
1. A method for operating a printing system comprising:
printing an inkjet image on a receiver using a hydrophilic ink capturing an image of the printed inkjet image on the receiver after a predetermined period of ink absorption;
identifying local areas of the image of the printed inkjet image on the receiver that have reached a threshold level of non-uniform distortion and where unabsorbed ink remains;
determining a distortion estimate for an extent to which the receiver will be distorted at a time when a second image is printed on the receiver based upon information from the identified areas;
generating a second print image based on the distortion estimate; and
printing the second print image.
2. The method of claim 1 , wherein the threshold level is within a range where effects of non-uniform distortion do not require a full image pixel adjustment.
3. The method of claim 1 , wherein the distortion can occur in one dimension, two dimensions or three dimensions.
4. The method of claim 1 , wherein the determination of the distortion estimate comprises considering a nature and extent to which the identified areas have distorted at a time of the image capture and an amount of ink deposited at each area, and generating a distortion estimate of the extent to which the receiver will be distorted, the nature of these distortions and anticipated interactions between adjacent distortions.
5. The method of claim 1 , further comprising providing a mapping or transform that can be used to determine a pattern of printing that can provide a desired printed outcome at a time when a second printing operation is to begin.
6. The method of claim 1 , wherein the distortion estimate is determined based upon a three dimensional model and/or analysis.
7. The method of claim 1 , wherein the distortion estimate can also consider factors inside of the printing system that may influence the progression of any of the distortions.
8. The method of claim 1 , wherein the second image is printed in registration with the printed inkjet image in accordance with the distortion estimate.
