Diazo photo emulsion instructions pdf
Add only one third of a bottle of water to diazo bottle and shake well before adding to emulsion. That light hardens the emulsion everywhere, except for where the black image is located on the film positive. A phototool is prepared which is a negative image of the desired copper electrically conductive circuitry, and this is typically a silver halide photographic emulsion, or diazo phototool film with emulsion. As an example, take a photopolymer emulsion that requires only 20% of the exposure time of a diazo or dual-cure if used on an exposure system with a multispectrum bulb. The sensitizer comes as a dry powder; fill the jar with water and mix, then combine with the emulsion. The new emulsion designs require better developer control to insure full development of the films emulsion. Vented warm air for an hour speeds up the drying, after which a fan is sufficient.

There are also three photo reactive film choices, indirect film, direct/indirect film, and photoreactive capillary films. The "new" diazo films have a new emulsion design vs the "old" diazo films. Diazo films are used to create a service master, directly copying the master film through contact printing. This method is one of the most exciting techniques of screen printing because it offers a wide range of possibilities. See the TDS for more and detailed info [25-30]°c1 1Drying time depends on the applied emulsion quantity. Must use/mix Diazo; Must work under yellow light *Use for Plastisol, Water base or Discharge inks.

add the entire contents to the emulsion and mix thoroughly until a smooth consistency is obtained. Stir With a clean, broad, flat plastic or stamless steel Instrument until the emulsion is uniform m color. Photo-Polymers are ready to use -vs-Dual Cure require mixing of Diazo activator.; Photo-Polymers have a shelf life of 12-18 months -vs- Dual Cure emulsions have 3-4 months after activation.; Photo-Polymers are fast exposing-vs-Dual Cure emulsions have a longer exposure latitude.; Dual-Cure are resistant to Solvent & Waterbase inks -vs-Photo-Polymers require a stencil hardener. We think our screen looks great only to find that we have a bunch of problems when it comes to exposing them. DZ 343 can withstand thousands of prints without the use of chemical hardeners and still reclaim easily.

The technique makes it possible to print fine line drawings, hand and commercial lettering, and photographic half-tone positives. The DIAZO Photo Emulsion Kit is a good way to start photo stencil screenprinting.
The copper surface is overlaid with a photo-resist layer which is typically a carboxylic acid containing polyacrylate. As the exposure progresses, the radiometer registers the energy it sees in microwatts.
ProChem® DXP PINK also has a very high solid content which makes for stronger durability and better resolution. Expose or burn images onto photo emulsions with high output UV Fluorescent lights, with accurate detail.
complicated relationship in their relative photographic speeds.
Shelf life for the sensitized emulsion is 4 weeks at 90°F, 8 weeks at 70° F, and 4 months when refrigerated. The general components of the polymer portion of the emulsion include acrylate chemicals and a photo initiator.
Dissolve the diazo sensitizer powder by adding lukewarm water up to the shoulder of the bottle. 1.2 Studies of non-silver based emulsion viz., Diazo, Polymer 1.3 Study of development, stop bath, fixation, chemicals and their functions. dissolving 0.6g of the diazo compound in 100g of the matrix PVA-emulsion in water together with the additives. Excellent durability, superior solvent resistance ・Pour diazo solution into emulsion. DIAZO – FILMS HANDLING INSTRUCTIONS 1A GENERAL Diazo films are direct-positive contact films for ammonia development. After pouring the diazo into the emulsion, check the inside of the bag for any remaining diazo. UV Black Light Exposure Unit The Xpo 2331 large screen capacity silk screen printing image exposure unit uses (10) unfiltered black lights to make textile, and graphic screen printing stencils.
