Concept 21 ADM 3.0/STM 6.0
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..
