Orange is a ready-to-use SBQ-photopolymer direct emulsion formulated for imprinted sportswear printing. It is formulated with a “masking color” that reduces light scattering—the major cause of loss of resolution. With Orange, it is possible to use less costly white mesh without the closing up of fine lines and details. Despite its anti-halation color, Orange is ultra-fast-exposing! It is perfect for shops with high stencil making throughput, as well as shops with fluorescent tubes or other low-intensity light sources.

 

Orange has high viscosity (6,000 – 8,000 centipoise) that improves control when coating screens by hand and makes it a good choice for coarse mesh. Its high solids content (44 - 46%) results in better mesh bridging and edge definition, and fast drying.

 

Orange resists plastisols, most washup solvents, and some water-based textile inks, and it is easy to reclaim.

 

Orange stencils are durable, will not become tacky under high humidity conditions, and have excellent wet strength and exposure latitude.

 

Orange reduces stencil-making time—in coating (because of its high viscosity), drying (due to its high solids), and exposure (due to its high photo-sensitivity despite its “masking color.”

Additional Information

  • Orange, high-contrast “masking” color
    - Improves resolution and definition
    - Saves mesh costs: use white instead of more-expensive dyed mesh
  • Ultra fast exposing
    - Fast stencil throughput for high volume shops
    - Assures thorough exposure, even with weak light sources
    - Dependable polymerization assures durability and ink resistance
    - Excellent wet strength, exposure latitude, and durability
  • High (44 - 46%) solids content
    - Dries quickly
    - Better mesh bridging; lower Rz value yields sharper printed edges
  • High (6,000 – 8,000 centipoise) viscosity
    - Easier to control during coating, even on coarse mesh
  • Water and Solvent resistant
    - Resists plastisols and many washup solvents
    - Resists some water-based inks, even without added diazo

  • Step 1: PREPARE THE FABRIC

Used or surface treated fabric need only be degreased using Magic Mesh Prep, Screen Degreaser Liquid No. 3, or dilute Screen Degreaser Concentrate No. 33. (Mechanical abrasion is an option for new fabric that is not surface treated. It increases the surface area of fabric for a better mechanical bond of the stencil, increasing printing run length. Use Microgrit No. 2 before degreasing. Abrading and degreasing can be combined in one step with Ulanogel 23.) A degreaser, Magic Mesh Prep also serves as a wetting agent and antistatic treatment. Screen fabric treated with Magic Mesh Prep can be coated with emulsion more evenly and will transfer ink more readily during printing.

 

  • Step 2: SENSITIZING

Orange is fully presensitized. No sensitizer need be added. Orange should be handled only under yellow safe light conditions.

 

  • Step 3: COAT THE SCREEN

Method 1: Apply one coat of emulsion on the printing side, then one coat on the squeegee side. Dry the screen thoroughly. Method 2: Apply two coats on the printing side, then two coats on the squeegee side, wet-on-wet. After each coating, rotate the screen 180°. Method 3: Follow Method 2 (above). Then, after drying the screen, apply two additional coats on the printing side, wet-on-wet.

 

  • Step 4: DRY THE SCREEN

Dry multicoated screens (Methods 2 or 3) thoroughly in a horizontal position, printing side down, at room temperature in a dirt- and dust-free area. Use a fan to speed drying. If using a commercial dryer, dry the screen with warm, filtered air, up to 104° F. (40° C.).

 

  • Step 5: CALCULATE THE APPROXIMATE EXPOSURE TIME

Refer to the Base Exposure Table (reverse side). Base Exposure Time X Exposure Variable Factors = Approximate Exposure Time.,

 

  • Step 6: MAKE A STEP WEDGE TEST

Use Ulano’s Exposure Kit to test exposures above and below the Approximate Exposure Time, or make a Step Wedge Test following instructions on the “Support Tab” video on our Web site: www.ulano.com. Optimum exposure is indicated when: ■ No positive outline or darkening of the emulsion color is observable if the exposure is increased. ■ The squeegee side emulsion is hard and not slimy after washout. ■ The print best duplicates the test positive at the required level of resolution.

 

  • Step 7: WASHOUT THE STENCIL

After exposure, wet both sides of the screen with a gentle spray of cold water. Then spray forcefully from the printing side until the image areas clear. Rinse both sides of the screen with a gentle spray until no soft emulsion is left on the squeegee side, and no foam or bubbles remain. Blot excess water from the printing side with newsprint (unprinted newspaper stock).

 

  • Step 8: BLOCKOUT AND TOUCHUP

Blockout Option 1: Before drying and exposing the coated screen, use excess emulsion from the coating step to cover the blockout area. Blockout Option 2: For non-water based-inks, after exposure and washout, dry the screen. Apply Screen Filler No. 60 or Extra Heavy Blockout No. 10. Touchup Option 1: Use excess emulsion and re-expose the screen. Touchup Option 2: For non-waterbased inks, use Screen Filler No. 60 or Extra Heavy Blockout No. 10 thinned with water.

 

  • Step 9: STENCIL REMOVAL

Use All-Purpose Ink Wash, Eco-Wash 160 or the least powerful ink diluent necessary, to remove all ink remaining in the screen. Use Screen Degreaser Liquid No. 3 to help remove ink and solvent residues that might impair the action of the stencil remover. Brush Stencil Remover Liquid No. 4 or Stencil Remover Paste No. 5 on both sides of the screen. Do not let the stencil remover dry on the screen. Wash the screen with a forceful spray of water. Use Walk Away Haze Remover or Haze Remover Paste No. 78 to remove ink and haze residues.
