How to use spray developer (DP-M500) for positive photosensitive substrates
Place the substrate to be developed in a bat.
*Please keep the substrate horizontal.
Spraying the developer will discolor the exposed pattern.
Cover the entire substrate with foam.
Once the entire substrate is covered with foam, leave it in place for 40 to 60 seconds.
After 40 seconds, the photosensitizer in the exposed area will dissolve.
Pull up the substrate while cutting bubbles.
Rinse the substrate with water.
Development is complete.
