Custom Lut-Property Preserving Hans Calibration, Hp Inc

Defensive Publications Series

This disclosure relates to the field of color calibrations in a print system. Traditional

calibration obtains change factors for each of the inks of a given system and applies these

factors - per ink - to the color resources. The changes are proportionally spread for ink

combinations (in a traditional pipeline) or NPacs (in a HANS pipeline). However, there are

cases where resources may use certain ink-drop combinations (NPs) for purposes and

used by later stages of the pipeline, where calibration must apply change factors such

that these custom NP properties are maintained after calibration. One example here is

the …

Emissivity Robustness Through Glass Temperature Control, Hp Inc

Defensive Publications Series

Temperature control is fundamental for MultiJet Fusion technology and

MetalJet technology. When monitoring temperature using a thermographic

camera (or any other noncontact thermometry technology) it is important to set

the camera emissivity setting to match the optical emissivity of the build material,

otherwise the camera readings will not be correct. In some materials emissivity

may vary from lot to lot and with recycling, it is therefore advantageous to make

the printmode robust to powder emissivity variations. This can be achieved by

controlling the temperature of the top lamps glass via pyrometer measurements.
