The advantage of an aluminum screen  

printing frame is the durability and longevity it retains. Unlike wood  

silk screen printing frames when exposing frames to water in a dip tank  

or washout sink aluminum frames will not warp. This will insure a flat frame  

through thousands of prints to come. Aluminum frames can also be stretched and  

re-stretched many times. The mesh and glue are simply removed from the frame  

using a professional tool that doesn't damage the aluminum. Once cleaned, the  

frames can then be re-stretched which will give you the ability to use that  

frame for years of hard work in your shop Business Cards & More! .

Aluminum frames are also light weight which makes shipping  

less expensive and saves you money in the long run. If you're looking to  

maximize performance in your shop, aluminum frames are a great item to add to  

your screen printing equipment.

More about screen printing mesh size: Different mesh sizes are used for different  

applications in the screen printing process. Mesh size is measured by how many  

threads of mesh there are crossing per square inch. For instance, a 110 mesh  

screen has 110 threads crossing per square inch. The higher the mesh count, the  

finer the threads and holes are in the screen. The size of the mesh has a lot to  

do with how detailed your image is and how thick the ink you are using is. If  

you have an image with extremely high detail, a lower mesh screen won't hold the  

high detail. The fine lines or dots in the image will simply fall through the  

holes in the mesh not giving you a correct representation of what your image  

should be. Also if you are using a thinner ink, the ink will also flood through  

the larger holes and soak onto your shirt or substrate making your image blurry  

as the ink bleeds. On the other hand, if you are trying to print a thicker ink  

(such as white) through to high of a mesh screen, barely any ink will print  

through the mesh. You will notice that different companies have different sizes  

available. If the mesh count is fairly close, such as the difference between  

155 vs. 156, 196 vs. 200, or 81 vs. 86, the difference is so negligible and  

small that it will not matter in your final results.

Since there are many variables involved in silk screen printing we  

can't tell you exactly what mesh sizes are used for what applications. However  

we can give you a general outline of what sizes to use for certain types of  

printing. Your basic and most standard mesh sizes are 110 and 156. 110 mesh  

lays a fairly thick layer of ink down. It's great for block text letters and  

larger spot color designs. It's also a recommended mesh for white flash plates  

because many times you will only have to make one print impression which speeds  

up production time. 156 mesh also lays down a little thicker layer of screen  

printing ink but offers you some higher detail ability in your image due to  

the finer mesh. Also if you are printing with a little thinner viscosity colors  

of inks, you may want to use the 156 mesh so not too much ink is passed through  

your screen. Lower mesh counts like 40-86 are used for shimmer and glitter  

inks. These inks have particles in them that will not pass through the typical  

mesh sizes. Therefore you need a lower mesh count with large holes in order for  

all the particles to pass through properly. Shimmer plastisol inks have finer particles in them so you could probably use an 86 mesh while glitter inks have much larger particles so it would be recommended to use a 40 or 60 mesh screen. 200 and 230 mesh are used for finer detailed images and thinner inks. These mesh sizes can hold larger half tone dots but are not  

recommended for four color process prints or fine detail half tone printing.  

Also graphic and solvent based silk screening inks that are much thinner should be used with these mesh sizes. Also if you would like a softer feel to the ink on your shirts you can  

print through these higher mesh counts which will let less ink through the  

screen giving you a much softer feel on the shirt. This can get tricky however,  

many times a duller distressed look is wanted for the artwork but if bright  

vibrant colors are desired (especially white) you will have a hard time getting  

the opacity thick enough using these higher meshes. 305 mesh is used for  

extremely high detail textile printing and fine halftone four color process and  

simulated process prints. (Learn more about process printing here.) Fine half  

tone dots need high fine detail mesh in order to hold and expose on. Higher  

meshes such as 355, 380, and 400 are used mainly for graphic printing with UV  

inks. UV inks are extremely thin and many times are used for high detail  

printing on signs, banners, or CD's. Using a higher mesh allows the automatic  

printers used in UV printing to regulate the amount of ink passed through the  

screen.

Exposure Notes: Different mesh sizes hold different  

amounts of emulsion, due to how big the holes in the mesh are. For instance a  

110 mesh screen will hold much more emulsion then a 305 mesh screen. While the  

difference isn't extreme, you will have to vary your exposure times slightly for  

different mesh sizes. A finer mesh screen that holds less emulsion will expose  

faster then a lower mesh screen that holds more emulsion. However, the  

difference is small so you may have to only vary as slightly as 5-10% in either  

direction and depending on mesh size in order to get maximum exposure  

performance.
