Avertissement concernant l’expédition par temps froid

Toutes les commandes d’émulsion expédiées par temps de gel sont considérées comme des ventes définitives et ne peuvent faire l’objet d’un remboursement ou d’un remplacement en cas de dommages dus au gel. 


L’émulsion peut être endommagée de façon permanente si elle est exposée, pendant le transport, à des températures de 0 °C (32 °F) ou inférieures. Veuillez tenir compte des conditions météorologiques avant de passer commande. Nous vous recommandons de commander avant l’arrivée du gel.


Proclaim est une émulsion photopolymère à base de diazo (à double polymérisation) formulée pour offrir une latitude d’exposition et une facilité de découchage inégalées, même en cas de sous-exposition et lorsqu’elle est utilisée avec des encres et des solvants de lavage agressifs. Si vous rencontrez des problèmes de récupération, c’est le produit qu’il vous faut ! Proclaim est polyvalente, à exposition rapide et offre une résolution et une netteté exceptionnelles.

 

Sa teneur élevée en matières sèches (37 %) offre un meilleur développement du pochoir à chaque couche, un excellent pontage des mailles grossières et un séchage rapide. Proclaim possède d’excellentes propriétés d’enduction et une grande durabilité, et résiste à une grande variété d’encres à base de solvant ainsi qu’aux encres UV à base d’eau. Proclaim convient parfaitement aux applications graphiques, textiles et industrielles polyvalentes. La latitude, la résolution et la définition des contours sont excellentes, ce qui la rend idéale pour l’impression de traits fins et de trames.

 

Proclaim est de couleur bleu clair ; vert clair avec ajout de diazo. Les zones exposées reprennent leur couleur bleue d’origine, offrant ainsi un indicateur intégré d’une exposition adéquate.

 

Pour un contraste optimal, utilisez le Red Blockout.

  • Step 1: PREPARE THE FABRIC

Used or surface treated fabric need only be degreased using Screen Degreaser Liquid No. 3 or dilute Screen Degreaser Concentrate No. 33. (Mechanical roughening 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. Roughening and degreasing can be combined in one step with Ulanogel 23.)

 

  • Step 2: SENSITIZE THE EMULSION

Proclaim is partially sensitized; therefore, it must be handled under yellow light. Dissolve the diazo sensitizer powder by adding lukewarm water up to the shoulder of the bottle. Shake well. Wait 15 minutes for bubbles to disperse. Pour the fully dissolved sensitizer into the emulsion. Stir with a clean, broad, flat plastic or stainless steel instrument until the emulsion is uniform in color. Close the container. Wait at least one hour for the emulsion to de-bubble. Write the date of sensitizing on the label.

 

  • Step 3: COAT THE SCREEN

Method 1: Apply one coat of emulsion to 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°. Dry the screen thoroughly. Method 3: Follow Method 2. Then, after drying the screen, apply two additional coats on the printing side, wet-on-wet. Dry the screen again. Method 3 optimizes the definition of printed edges.

 

  • 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 accelerate the drying. Avoid high humidity. Under humid conditions, dry the coated screen with warm, filtered air up to 104° F. (40° C.) in a commercial dryer. Use a dehumidifier in the drying area, if possible.

 

  • Step 5: CALCULATE THE APPROXIMATE EXPOSURE TIME

From the Base Exposure Table below, select the type of light source you have and its wattage or amperage. The exposure times indicated are for 305/inch (120/cm.) white fabric at an exposure distance of 40 inches (= ca. 1 meter), using coating Methods 1, 2, or 3. The exposure time shown for the light source and coating method being used is the Base Exposure Time. Multiply the Base Exposure Time by all relevant Exposure Variable Factors (table, below) to find the Approximate Exposure Time.

 

  • Step 6: DETERMINE THE OPTIMAL EXPOSURE TIME

Make a Step Wedge Test (instructions can be found in the Ulano Direct Emulsions Technical Data Booklet) or use the Ulano Exposure Calculator Kit—carried through to actual printing—to determine your optimum exposure time. Optimum exposure is indicated: ■ At that exposure time when the emulsion first reaches its maximum color density, and the edges of the positive do not "resolve." ■ The squeegee side emulsion is hard, not soft or slimy. ■ The print best duplicates the test positive at the level of resolution that the job requires.

 

  • Step 7: WASHOUT

Wet both sides of the screen with a gentle spray of cold water. Then spray the printing side forcefully until the image areas clear. Rinse both sides 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 unprinted newspaper stock.

 

  • Step 8: BLOCKOUT & TOUCHUP

Blockout Option 1: Before drying and exposure, 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-water-based inks, use Screen Filler No. 60 or Extra Heavy Blockout No. 10 thinned with water.

 

  • Step 9: STENCIL REMOVAL

Remove ink from the screen using the solvent or solvent blend recommended by the ink manufacturer. 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 Haze Remover No. 78 or Ghost Remover with Ghost Remover Activator to remove ink and haze residues, if necessary.
