Ulano Orange Photopolymer Emulsion
IMPORTANT: Texsource ships in-stock items as orders are placed, and cannot guarantee that temperature-sensitive items, like emulsions and emulsion removers, will not be exposed to freezing temperatures in transit. Texsource is not responsible for items damaged by exposure to extreme temperatures.
Ulano 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.
Emulsion Exposure Differences
Proper screen exposure must take many factors into account – the emulsion type, coating thickness, exposure unit, etc. As a general guideline for the different emulsion types (diazo, dual cure, and photopolymer) use these times as a reference.
Photopolymer – These are typically the fastest exposing emulsions, with many exposing correctly from 30-50 seconds. The shortest times can be seen when using a newer LED-type exposure unit.
Dual Cure – If you have established a good exposure time with photopolymer emulsions, you can typically add 90 seconds (1.5 minutes) to that time for most dual cure emulsions.
Diazo - If you have established a good exposure time with photopolymer emulsions, you can typically add 210 seconds (3.5 minutes) to that time for most diazo emulsions.
These times will depend heavily on your exposure unit and should only be considered as a starting point.
