INSTRUCTIONS FOR HANDLING & USE
For your safety, avoid contact with skin or eyes. For best results, use your SaatiPrint Grafic HU Dual Cure Emulsion under a yellow safety light. Avoid exposure to daylight, quartz/halogen lamps, cool white fluorescent lamps or discharge lamps.
Prepare Diazo as per instructions on the bottle. Add the entire contents to the emulsion and mix thoroughly until a smooth consistency is obtained. Write the date of sensitizing on the label and then cover the sensitized emulsion and let stand for a few hours to enable air bubbles to escape. Store sensitized emulsion in cool conditions and use within one month for best results.
Mesh Preparation and Degreasing:
Degrease and abrade new mesh with Direct Prep 1 (abrasive gel) in order to optimize stencil adhesion; dry and store the screen in a dust free, dry environment prior to coating. For further applications, thoroughly degrease the mesh prior to use with Direct Prep 2 (degreaser).
Using a high quality scoop coater or coating through, 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 substrate side of the screen after the initial coats have dried. 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.
Thoroughly dry the SaatiPrint Grafic HU Dual Cure Emulsion coated screen 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 one of two calculators now available (Exposure Calculator and 21 Step Sensitivity Guide) to determine correct exposure time for a complete cure.
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.
Remove all ink residues immediately after printing with an appropriate solvent. Remove stencil with Remove ER series and a pressure washer. For stains and ghost images, use Remove HR series followed by a pressure washer.
INSTRUCTIONS FOR STORAGE:
When sealed in the original container and stored at temperature between 20 and 25°C, GRAFIC HU will maintain original properties for 18 months from the date of production.
Extending the Life of Your SaatiPrint Grafic HU Dual Cure Emulsion

Coated, unexposed screens can be stored as long as one month in a clean, cool, dry and completely dark area.
Use only distilled water to dissolve diazo sensitizer.
Expiration date. Always check the expiration date on sensitizer bottle to assure freshness.
