I have seen yellow mesh and of course white mesh. But today I opened my new package of screens from Ryan Screen Supply and one of the 180 count screens has orange mesh. I didn't even know there was orange mesh.
Anyway, how does the orange color affect burn time? Is it a difference the same as between yellow and white? Should I do a slightly shorter or longer burn time with orange compared to white?
Thanks

Dyed fabrics help eliminate halation or the scattering of light during exposure, by absorbing the light rays.

Mesh fabrics are available in clear (or sometimes called white) yellow, orange, and red. Each of these colors performs a unique function. The clear or white mesh is used for those images with little or no detail. Yellow is the most common mesh color for mesh counts above 110 tpi. Orange is used by those printers who want a bit more detail and reputation. Red is used mainly by balloon printers looking for detail in the slightly inflated balloon so that when the balloons are completely inflated the detail will be quite good.

Each of the colors will require increased exposure times based upon the density of the color. As a rule, exposure times for fabrics of the same mesh count will increase as follows, with clear or white fabric as the reference:

Clear or White Mesh 100%
Yellow Mesh 125% of the Clear Exposure
Orange Mesh 150% of the Clear Exposure
Red Mesh 200% of the Clear Exposure

Thanks for explanation, Bill. I was a bit curious about the difference in exposures times for different mesh colors myself.
