All purpose solvent and water resistant photoemulsion.
• Red one part pure photopolymer emulsion with universal ink resistance
• SBQ technology, exposes 6 times faster than two part emulsions and leaves no diazo stains
• Easy Reclaim features/benefits
• 42% solids and high viscosity for easy coating and good bridging on all mesh counts
• Universally resistant, can be used with solvent based, UV, and water based inks, yet is easy to reclaim
• Recommended for use with discharge inks as is, without using diazo or catalyst for stencil hardening
Directions for Use
Handle under yellow safelight or low wattage tungsten lights. Avoid exposure to daylight, quartz/halogen lamps, cool white fluorescent lamps or discharge lamps.
Sensitizing and Mixing
Emulsion is presensitized during production and does not require mixing.
Mesh Preparation & Degreasing
Degrease and abrade new mesh with Saati Direct Prep 1 in order to optimize stencil adhesion; dry and store the screen in a dust free, dry environment prior to coating. For more applications, thoroughly degrease the mesh prior to use with Saati Direct Prep 2.
Using a high quality scoop coater or coating trough, apply one or two coats to the substrate side of the screen, followed by one or two coats on the squeegee side. For a thicker stencil, apply additional coats to the squeegee side prior to drying. For a higher quality stencil with a minimal increase in stencil thickness, apply one or two additional coats to the substrate side of the screen after the initial coats have dried.
Remove all ink residues immediately after printing with either SAATI Ink Remover IR11 or IR18. Remove stencil with SAATI Emulsion Remover ER1, ER2, ER5, ER6 or ER10. For stains and ghost images, use SAATI Haze Remove HR3 or HR9 followed by a pressure washer.
Drying & Storage
Thoroughly dry the coated screen at a maximum temperature of 104°F (40°C) in a dust free, dark or yellow light area, with the substrate side facing down to optimize stencil quality. Coated screens should be stored in a dust free, dry, safelight environment.
Ensure that all surfaces, emulsion, film and glass are free of dust to minimize pinholes. Contact the emulsion side of the positive with the substrate side of the screen and secure in position before placing the screen in a suitable vacuum frame. Many variables, such as lamp type and age, distance from lamp to screen, mesh type and coating thickness, can affect exposure time. Perform an exposure test with an exposure calculator to determinate correct exposure time for a complete cure. Developing Wet both sides of the screen with a strong, finely divided spray of water and continue washing out until all image areas are fully open. Rinse both sides of the screen and dry thoroughly before use. A properly exposed and developed screen will not leave residues on the squeegee side.
Post expose with daylight or exposure lamp to produce a more water-resistant stencil.

Our shop goes back and forth between plastisol and water based ink, and this is our go-to emulsion. It exposes quickly and stands up well, even after being cleaned several times. Highly recommend.
The product is good and works great for my needs. I like the old container better than the new one. (screw lid vs. snap on)
This is the best one-part, pure photopolymer emulsion I have ever used. Even when developing with a fluorescent light source I can burn for a minute and get good screens. Varying the thickness or adding Diazo 11 can produce some super sharp screens. I am able to hold 10% dots easily and I'm sure with a little experimentation the dot size will go lower! Highly recommended!!! Spot Color Supply has a great price also! 30+ years in screen printing.
