Claim 7:
8. An apparatus comprising:
a printhead;
a dryer adapted to dry ink printed on sheets of media by the printhead; and
sheet feeders adapted to move the sheets of media to and from the printhead and the dryer; and
a controller adapted to control the printhead, the dryer, and the sheet feeders,
wherein the controller is adapted to identify distortable ink colors in a print job,
wherein the distortable ink colors interact with one another when printed in a same printing pass on a same area of a sheet,
wherein the controller is adapted to control the printhead and the sheet feeders to separately print the distortable ink colors in different print passes,
wherein the controller is adapted to control the printhead to print heat-activated alignment marks in a first pass of the different print passes,
wherein the controller is adapted to control the dryer and the sheet feeders to dry the ink printed on the sheets of media between the different print passes,
wherein the heat-activated alignment marks become temporarily visible after being activated by the dryer, and
wherein the controller is adapted to control the sheet feeders to align the sheets of media in the different print passes occurring after the first pass using the heat-activated alignment marks while the heat-activated alignment marks are visible after activation of the heat-activated alignment marks by the dryer when the dryer dries the sheets of media between the different print passes.
