5. Note:

1) Platemaking conditions: light of 80 watts (11.7mW/cm2 under 365nm), platesetter temperature 24-30°C.
2) R170L divides two systems; the former is more resistant to UV inks.
3) All the above data is depended on our plate-making device. Due to the different requirements of plate-making device, UV lamp power, relief depth and print image, the above recommended time can be changed suitable. Customers should test on their own device for optimum plate quality.

6.Storage & Guarantee

1. Unexposed plates should be stored in cool areas (4-32 degree)away from heat. The plates must be placed flatly, and protected from contacting UV light. It is recommended to unpacked and handled in yellow light.
2. Printing plate should be avoid excessive white light, irradiating from sunlight and exposing in high concentrated ozone environments for a long time either.

3. After being unloaded, the plates should be cleaned thoroughly.
