- What is this emulsion for?
QLT universal emulsion is particularly suitable for exposing screens on which Plastisol and Solvent-based inks are to be used.
For printing with water-based inks, our tests have shown that a maximum output of approximately 200 prints is possible.
But it's still a Universal Screen Printing Emulsion, suitable for all ink types.


- Is it necessary to add Diazo?
No, for this type of emulsion adding Diazo is not necessary.
In fact, it is a ready-to-use emulsion.
If kept refrigerated at 5°C, it can last up to 90 days.
In any case, it must be stored in a dark location and in a sealed container.


- What stripper can be used to remove it?
This type of emulsion can be effectively removed from the screen using the Quasar Liquid Stripper.


- What light needs to be used for exposing the screen?
QLT emulsion can be exposed with both white and UV light

    • I bought emulsion for cold light exposure, but I can no longer get the exposure timeframes exactly right. If I expose the frame for 15/20 minutes the lines printed on the gel aren't visible. Perhaps the stronger the light, the shorter the exposure time, is that right?
    • That's correct, the stronger the light, the shorter the exposure time.
      Therefore, if the lines aren't visible, the exposure time needs to be reduced.

      I don't know anything about the exposure system you're using, but we know for sure that, for the same exposure system, the ready-to-use emulsion for white light needs to be exposed for approximately half the time with respect to a diazo emulsion.

      I suggest trying an exposure time of 10 minutes, if the lines still aren't visible, try 5 minutes.

      If the exposure is insufficient, you can always increase it until you find the correct intermediate time.
