Abstract
The following described arrangements and procedures generate a smudge resistant image with an ink jet imaging device. Specifically, in an image printing zone on the ink jet imaging device, a first carriage generates an image on a print medium. Then, in an image protecting zone on the ink jet imaging device, a second carriage deposits an overcoat solution and a fixer solution onto the image to form a substantially smudge resistant image.
Claims2
A method for generating a smudge resistant image with an ink jet imaging device, the method comprising:
- generating, using a first carriage in an image printing zone, an image on a print medium;
- depositing, using a second carriage in an image protecting zone, an overcoat solution and a fixer solution onto the image to form a substantially smudge resistant image;
- wherein generating the image further comprises depositing, with a first printhead of the imaging device, an ink colorant onto a print medium to form an image, the first printhead being independent of a second and a third printhead of the imaging device;
- wherein depositing the overcoat solution further comprises depositing, by the second printhead, an overcoat solution over the image to protect the image from abrasions, the overcoat solution being water soluble;
- wherein depositing the fixer solution further comprises depositing, by the third printhead, a fixer to the overcoat solution, the fixer being water soluble;
- and
- wherein the overcoat in combination with the fixer are water insoluble and hence substantially protect the image from smudges.
A method for generating a smudge resistant image with an ink jet imaging device, the method comprising:
- generating, using a first carriage in an image printing zone, an image on a print medium;
- depositing, using a second carriage in an image protecting zone, an overcoat solution and a fixer solution onto the image to form a substantially smudge resistant image;
- wherein generating the image is performed by at least one first pen positioned on the first carriage;
- and
- wherein depositing the overcoat and fixer solution is performed by at least one second pen positioned on the second carriage
- wherein the at least one second pen has a drop volume greater than the drop volume of the at least one first pen;
- and wherein the at least one second pen has a drop volume in the range of 4 pl to 64 pl.
