HPS - The Process

The HPS is quick and easy to use with minimal training required.

The whole process takes 2-3 minutes and involves no pre-treatment.

    1. Place the thermal paper into the HPS
    2. One push of a button
    3. The heat plate carefully heats the thermal paper
    4. The optical system detects the slightest change
    5. The cooling cycle begins
    6. The mark is preserved

The evidence is now ready for image capture and enhancement using your regular photographic equipment.

The HPS does not affect the use of Ninhydrin to develop prints on the non-thermal side of the paper and DNA swabs can be taken before if required.
