Ceras Mart Emulsion Aims to Optimize Screen Printing Efficiency
October 26, 2026
Screen Sol RM Blu, a photopolymer emulsion from Ceras Martí, is designed for water-based screen-printing inks while also accommodating plastisol and solvent-based systems. The product requires sensitization with the supplied Diazo additive before coating and exposure, and it can be processed with UV or white-light sources. Its storage life depends on temperature once the Diazo has been mixed in.
Core applications and ink compatibility
Screen Sol RM Blu is formulated primarily for water-based ink systems, where its chemical properties are intended to provide stable performance during stencil making. The emulsion is also compatible with plastisol and solvent-based inks, according to the product specifications.
That broad compatibility allows printers to use a single emulsion across multiple ink types, reducing the need to switch products for different jobs. It also simplifies inventory management and lowers operational complexity in the screen-printing workflow.
Technical specifications and handling
Before use, Screen Sol RM Blu must be sensitized with the Diazo sensitizer supplied in the package. The two components must be mixed thoroughly before coating the screen and proceeding to exposure.
| Parameter | Requirement or note |
|---|---|
| Ink compatibility | Water-based, plastisol, and solvent-based inks |
| Sensitizer | Diazo supplied with the product must be added |
| Recommended light source | UV (preferred); white light also possible |
| Stripping | Standard screen-printing stripping agents are sufficient |
The emulsion can be exposed using a UV light source, which is recommended for optimal curing. In settings without specialized UV equipment, white light can also complete the stencil-making process, though exposure parameters should be verified in practice.
Storage and shelf life
Once Diazo has been added, the emulsion’s useful life is affected significantly by temperature. Proper storage is necessary to maintain consistent stencil quality and avoid premature curing.
- Room-temperature storage: At 20°C, the mixed emulsion has a shelf life of 30 days.
- Refrigerated storage: At 5°C, the shelf life extends to 90 days.
- Environmental requirements: The emulsion must be kept sealed in a dark place to prevent light exposure from causing premature curing.
These conditions apply after sensitization. Printers should label and date mixed emulsion and monitor storage temperature to remain within the stated limits.
