Concept 21 ADM SF/STM SF
Super concentrated fountain solution system
Description: A unique mild acid fountain solution chemistry system designed specifically for
managing print characteristics and performance on press. Concept 21 allows
press operators to manufacture their own specific fountain solution on-site to
meet specific press needs. Precision blending technology mixes proprietary,
ultra-concentrated chemistry for concise dosing of the components into the
press mix. The ADM is comprised of the gum and desensitizers to maintain a
clean non-image area, while the STM is comprised of the wetting agents and
solvents to keep water settings low and the water system clean..
Directions for
Use: Initial Start-up:
Start Concept 21 ADM Series at the #4 setting on the graduated scale.
Start Concept 21 STM Series at the #7 setting on the graduated scale.
