Parameters

Analogue Positive Plate

SP II is a robust positive analogue plate for medium- long runs for application on equipment with ultraviolet light emitting at 320-450 nm.

SP II has good developing tolerance and excellent exposure latitude.

On press SP II plate provides stable ink/water balance. Due to its specific hydrophilic treatment allows fast start-up with low wastepaper and ink savings.

STP-G is compatible with the main developers of the market and has a very good developing latitude.

● Wide exposure and developing latitude

● Good dot reproduction

● Excellent and stable ink/water balance

● Compatible with the main developers in the market
