HP Stitch Guidelines for Improved Digital Dye Sublimation

The HP Stitch Dye Sublimation printer with HP Color Tools is a unique printing platform that simplifies the creation and control of color calibrated print environments. HP CLC (closed loop color calibration) is a unique system that yields acceptable ink limits and CMYK ink channel linearization. The HP Color Tools Easy Profiling System is simple to follow. Profile options are set automatically, so the process is substantially foolproof. The profile produces pleasing skin tones and commercially acceptable colors. The grayscale appears correct to the eye.

Improved individual CMYK channel limits on the HP Stitch will result in a higher quality color gamut both in terms of overall size and color accuracy. This can be achieved by imposing CMYK channel limits on top to the HP CLC limits.

This table presents approximate L*a*b* values that are recommended goals - not standards  - for dye sub ink channel limits on soft-knit fabric. Do not treat them as pass-fail objectives.

• Set the Cyan channel limit so the hue chroma curve just crosses the vertical axis. Make the a* value slightly negative. Cyan is near max chroma at that point so the L* value will be near a minimum.
  
• The aim for the Magenta is to maximize the a* value. If the Magenta limit is too high, the a* values get smaller and the L* values start to reverse.
• Yellow ink has a big influence on printed color. Make sure the ink is limited before the L* values start to reverse.
