The blue line FOTOCOAT
helps to copy the images onto the plate with register accuracy. The FOTOCOAT
system is supplied in two parts - the liquid in the bottle and the exact
quantity of diazo powder in the plastic bag. Before use, add the diazo
powder to the liquid, close the bottle and mix briefly by shaking.
The ready mixed FOTOCOAT is applied onto the plates in thin and even layers using a cotton pad. Continue to spread until the plate is dry. The dry plate is then exposed in the exposure frame together with the copy; the exposure time is between 20 and 40 seconds.
After the exposure the plate is developed on a table using the FOTOCOAT DEVELOPER. Use a cotton pad moistened in ready mixed developer and evenly moistens the surface of the plate. Depending on the thickness of the coating, the image gradually becomes visible, turning grey or black. When the image is fully developed, wipe the surface dry with a cotton pad - do not wash!
Finally, use a brush to coat the cutting edges with our EDGE PROTECTION VARNISH. Normally, this is step is not required. Only when using UV varnishes with direct varnish application, the front edge should be sealed with our protective varnish to prevent the edge from swelling. The STRIP PLATEŽ is now ready for use.
