it depends on the manufacture of the emulsion, the power and type of lighting, the mesh count on the screen and the type of transparency being used. some emulsion suppliers will provide some help with the times, some will not. trial and error works. find your baseline and go from there. the coarser the mesh count, the longer the screen will need exposed. if the entire emulsion coating is washing out, go longer. if the image is not washing out, go less and make sure your transparency is DARK! if the mesh is dyed a color other than white, add 10% to time for the same mesh count in white.
this is just the start of the frustration. good luck. You can supposedly make this out of potassium dichromate and Elmer's glue. I've worked with potassium dichromate, though. It's not something I would want anyone to do--this is a very dangerous, toxic, carcinogenic chemical that will give you a case of dermatitis that won't go away. Some things you just need to buy.

What is the standard mixing of photo emulsion and sensitizer?
The standard mixing ratio of photo emulsion and sensitizer is typically 1 part sensitizer to 12 parts photo emulsion. This combination allows for proper light sensitivity and adhesion to the screen mesh for effective screen printing. It is important to mix thoroughly and follow the manufacturer's instructions for best results.
What processes are involved in online photo printing?
Online photo printing uses the process of sending photos (usually .jpegs) to a specific print site. That company either prints it on site or send it out. Customers may have the option of picking their photos up directly or having them delivered to their home.
What is the name of the dots used in photo journalism?
Oddly enough, they're just called "dots," and are part of what's commonly known as a "halftone screen." The number of dots per inch determines the resolution of the printed halftone photo (the more dots, the sharper the picture -- 150 dpi allows for much finer detail resolution than 72 dpi). The reason this effect was required is that offset printing is not capable of reproducing shades or gradations of tone -- there's either ink on the paper or not. Reducing a continuous tone photo to a series of dots allows it to be reproduced on a printing press. Without the dot structure, the press would simply print a blotch of ink. Traditionally the halftone was achieved by laying a reusable, semi-transparent screen of the desired frequency (number of dots per inch) over high-contrast photographic paper on an enlarger (or by a similar process on a "line camera," but that's a whole 'nother topic). Bright areas of the picture were thus translated to small dots on the paper; darker areas comprised larger dots. Nowadays, most pre-press operations use scanners, computer graphics programs and digital output systems to produce halftones.
How do minerals containing uranium darken photographic film?
Uranium minerals emit radiation that causes silver halide crystals in photographic film to undergo a process known as fogging. This fogging results in darkening of the film, affecting the quality of images produced.

Can you use polystyrene with polyvinyl alcohol polyvinyl acetate to make screen photo emulsion?
Polystyrene, polyvinyl alcohol, and polyvinyl acetate are not typically used in screen printing emulsions.
