Automated control ensures residue-free surfaces and precise screen definition. This guarantees maximum emulsion adhesion and full reusability of the screen. Functional preparation & developing Optimize emulsion adhesion through controlled degreasing and ensure finest image details with precise washout after exposure. Our technology guarantees sharp edges without manual risk. Gentle total cleaning Remove ink residues and screen layers in a single process without damaging the mesh. Precise chemical dosing eliminates even the most persistent ghost images while fully maintaining mesh stretching. Efficient resource cycle Protect the environment with integrated filtration and reclaim systems. The closed-loop process minimizes water and chemical consumption while reducing wastewater impact. ## Maximum cleanliness for reproducible screen results. Clean mesh is not a coincidence, but the result of controlled chemistry. Where manual cleaning reaches its limits, automation ensures the long-term value of your screens. By precisely balancing spray pressure and chemical exposure time, even the most stubborn residues are removed without affecting the sensitive mesh structure. The result is a chemically neutral screen, ready for the highest demands. ### Optimal wetting Controlled degreasing adjusts surface stretching to ensure perfect emulsion adhesion without coating defects. ### Mechanical protection Defined pressure parameters prevent loss of mesh stretching and significantly extend screen lifetime. ### Consistent cycle times Standardized washing cycles ensure predictable production times and operator-independent cleaning quality. Process Steps ## From contaminated screen to neutral surface An efficient workflow ensures quality and longevity of your screens. 1\. Requirement analysis & program selection Depending on ink system and contamination level, the ideal cleaning program is selected to precisely match chemistry and time to the application. 2\. Intelligent spray technology Our specially developed V2A stainless steel nozzles ensure complete coverage. The unique service cap allows direct maintenance on the spray pipe without stressing the thread through disassembly. 3\. Intensive cleaning & decoating Under controlled pressure, emulsions and particles are removed deep into the mesh. The chemical-resistant nozzle design prevents spray distortion caused by clogging, ensuring ghost-free results. 4\. Ecological fluid treatment Used water and chemicals are filtered directly within the system and returned to the process cycle. This conserves resources and minimizes disposal effort.
