I remember I did this as a project in high school super fun. I want to try it again.

Thank you very much for posting this video.

Length of exposure varies depending on the size of screen and the lamp height. If you were to expose an 8"x10" screen with a 250W photo flood bulb positioned at a height of 16" from the screen, exposure time is 7 minutes; 10"x14" screen at 16" lamp height is 8 minutes, and a 12"x16" screen at 18" lamp height is 10mins

You can go to a hardware store to have the glass cut. It does not have to “fit” in the screen, it can be cut larger, if you expose from the bottom of the screen. It is not necessary, but will produce a crisper image. If you don’t use glass, you can use cellophane or scotch tape to secure the image to the screen.

Very ideal tutorial for Photo Emulsion Proocess

If you want to speed it up, you could, but use low or no heat on the hair dryer. Heat can cause the emulsion to activate. Make sure you do this in the dark.

Thanks!!for your instructions

You are welcome!

This just in! Straight from our Speedball Chemists, here's what we were able to find out--Our Photo Emulsion has been widely used in the past for etching copper plates using Ferric Chloride and Nitric acid solutions, but we are not aware of the Nitric Acid:water ratio utilized.

We are using a 250W BBA bulb that is available in our Ultimate Diazo Fabric Screen Printing and Diazo Light Kits.

This beats how diazo printing was done in the 70s...with photo projectors!!!

Is there a waiting time between when you mix the sensitizer with the photo emulsion and application to the screen? Say 1 hr or more???

Must I used speedballs squeegees also?

It is just a personal preference. On smaller screens, such as the one featured in the video; some people prefer using a squeegee. Scoop coaters are good for larger screens that have more area to cover, but again it all depends on the artist & their preference.

Yes, you must dissolve the sensitizer in water and then mix with the photo emulsion.

Thanks!!!

Thank you

can i use stenciling sheets instead?

This can be difficult because once you mix the Sensitizer with water, the shelf life on the Sensitizer begins. If you have some accurate scales, you can remove 1.08 grams of the paste and dissolve in about ¼ oz of water. Then pours this into 104 grams of the Diazo Photo Emulsion. The remaining Sensitizer can be used later.

You would not be able to remove all of the Sensitizer from the small bottle without the water. It is a very thick material that would be difficult to remove. The weights in this bottle are measured for a precise mixture and if any of the Sensitizer remains in the bottle, you would likely get a poor exposure and washout of the stencil.

thanks

It appears that the sensitizer was not completely dissolved in the water prior to mixing with the emulsion. Your screen should still work, but you may get some washout in the areas of the black streaks. Try to avoid putting your image over these areas with streaks. If you have some washout in the streak areas, then apply screen filler to block any openings.

Well, it could be done, but there would be some waste and you would need some very accurate scales. The time starts ticking once the sensitizer is dissolved in the water. The correct ratio would be 1.08 grams of the sensitizer paste, dissolved in ½ ounce of water, then mix into 104 grams of the blue diazo sensitizer.

how long can you keep a coated screen with emulsion and not exposed. Stored correctly. I've been in the hospital for a couple of months Are they still good?.

First, we're so sorry to read of your time in the hospital and hope that you are fully recovered and feeling great now! To answer your question, we usually would only recommend up to about a month, and even then I would usually expose at a reduced time. Some reaction will take place in the dark overtime. Since it has been more than a month, we would recommend trying to wash out what you can with warm water. If it won’t all come out, then let it dry, then use the Photo Emulsion Remover to reclaim the screen.

You do not need a darkroom to complete the photo emulsion process. Once you have coated your screen you will need to place it in a dark area to dry. However, once it is dry you can expose it to your light source - no darkroom needed!

This there so many potential light sources available for a printmaker to choose from, the only exposure times we are able to guarantee are those paired with the recommended light sources (250W BBA photoflood or Speedball LED Lamp) from our offering. Any deviation from those sources would require experimentation and evaluation in your studio specific to your screen size.

I purchased the emulsion and sensitizer seperately. The emulsion is 26.4 fl oz. The sensitizer bottle is only 2fl oz. What amount of sensitizer per emulsion? I cant seem to find this anywhere. No instruction came with my order.

What you have is the perfect size for each. If you add water to the 2fl oz bottle and mix per the instructions, it is pre-measured to be ideal for use with the 26.4 fl oz Emulsion. Happy printing!

If printing on paper, we would recommend our Acrylic Screen Printing Ink.

Both types of our Fabric Screen Printing Inks can also be used to print on paper, but not with the professional-grade results that we would expect from the Acrylic Screen Printing Inks line. Paper is a highly personal thing, but we love our Arnhem 1618 Paper or Speedball Printmaking Paper lines for the process!

That's a good question! Diazo Photo Emulsion has a three-year shelf life if not mixed. Once sensitized it has a shelf life of four weeks at 90º F., eight weeks at 70º F., and four months when refrigerated. If you don't feel like storing mixed unused photo emulsion, check out our Speed Screens Kit which comes with pre-coated screens ready to be exposed.

The Sensitizer contains the exact amount needed to be mixed with the larger Photo Emulsion bottle's contents. The second larger bottle that you see in this shot is not utilized until the end of this video (which is not shown here in its entirety) and is used for cleaning the screen--it is Diazo Photo Emulsion Remover.

Great question! You do not need to coat the screen in a dark room when coating the screen initially. After coating, the screen should be stored in a dark area to dry. If you decide to add an additional coat for larger print runs after the initial coat has dried, we recommend doing so in a dark room.

Length of exposure varies depending on the size of screen and the lamp height. If you were to expose an 8"x10" screen with a 250W photo flood bulb positioned at a height of 16" from the screen, exposure time is 7 minutes; 10"x14" screen at 16" lamp height is 8 minutes, and a 12"x16" screen at 18" lamp height is 10mins.
