Abstract
An example method to determine the change of a print medium due to heat dilatation or contraction is described. In that example the thickness before and after heating is determined and an offset value may be calculated to calibrate a print head to print medium distance.
Claims15
A method to determine a change of a print medium comprising:
- determining a first thickness of the print medium;
- heating the print medium, so that the print medium changes to a second thickness;
- and
- measuring the second thickness of the print medium.
1 more element
A non-transitory computer readable storage medium comprising instructions that, when executed by a processor, cause the processor to:
- determine a first thickness of a print medium before heating;
- determine a second thickness of the print medium after heating;
- and
- calculate an offset value based on the first and second thickness to calibrate a print head to print medium distance.
1 more element
A system comprising:
- a heat element to warm a print medium, so that the print medium having a first thickness changes to a second thickness;
- a controller to determine the first thickness of the print medium before heating and the second thickness of the print medium after heating;
- and
- a print head,
- wherein the print head is movable relative to the print medium to adjust the print head to print medium distance.
