PHOTO-NAMEPLATES WITH SELECTACOLOR

Use SelectaColor to make labels, nameplates or placques, in black or color, without special equipment.

Handle SelectaColor under dim room light, avoiding direct daylight or direct fluorescent light. A safelight is not necessary, but for longer periods of time, as when the sensitizer is drying, near or total darkness is preferred.

Coat Selectacolor by brush or sponge. The coating should be adequate to cover but no thicker than necessary, as too thick a coating can limit light penetration.

Dry thoroughly in the dark under room temperature with circulating air from an electric fan. The material can be stored overnight before exposure. Longer storage may make development difficult.

Expose through a high-contrast transparency held in contact by a glass plate. The transparency can be either negative or positive, depending on the desired effect.

Exposure will be fastest -- approximately 3 to 6 minutes at a distance of 2 feet-- with a halogen bulb. Sunlight is another useful exposure method. Other light sources may require a significantly longer exposure. Ordinary household incandescent bulbs will require an impractically long exposure and should not be used.

Develop by brushing or sponging the surface very gently with cool tap water to gradually dissolve the unexposed areas, revealing the image. Do not rush this step, as it may take several minutes for the image to appear. When the image is fully developed, blot and dry.

Troubleshooting: If the unexposed areas do not dissolve, it indicates that drying time has been too long, or over-exposed to light. Conversely, if the coated surface blisters or softens, it is because of too short a drying time or under-exposure.

After drying, additional colors can be applied over the original image and the process repeated for multiple exposures.
