Some of the Benefits of Newman Roller Frames

Low tensions screens create a large amount of printing distortion. This
distortion will exist for each color of a multi-color print. The
distortion is so large that it is difficult  and if not impossible to
print in register using non-trapped ( butt registration ) art work; or
layered ink on top of itself for brighter colors, or for high quality high density specialty printing. The high tension of the Newman Roller Frames will allow a printer to print distortion free, exactly the same
size of the stencil's image of the original art work. The higher the screen tension the lower the off-contact distance of the screen is above the shirt or paper during printing. The lower the off-contact distance during printing the more accurate the printed image will be by a factor of 4. Conversely the lower the screen tension and the higher the off-contact distance during printing, the more distorted the image will be during printing. This distortion will increase the longer the print run is.

It is important the the screen tension be high - 45 to 65 Newtons/cm or
higher. It is also important that the tension be uniform in the print
area preferably between + or - 1 Newton/cm, or within no more than 2
Newtons/cm. The NRFrames easily do that with proper training and a small amount of practice. After printing all screens loose tension from the heavy squeegee pressure. With the NRFrame you just put the frame back on the Newman Roller Master, and in 3 to 6 seconds the screen is re-tensioned back up to its original tension. The more that a screen is used and the more that it is re-tensioned the stronger that high quality polyester becomes. The most accurate high quality printing should be done on previously print, reclaimed, and re-tensioned mesh- not virgin mesh.

The higher and more consistent that the screen tension is, the thinner
and brighter the ink deposit will be. The higher tension will also
control the thickness of ink deposits in general, and hence, will give
the printer much more control and accuracy on all of their color
balances. This will be true for transparent, semi-transparent, and
opaque inks.

The higher screen tension will also allow a printer to print faster for
both manual and automatic printing. The ink will flow about 30%  faster
and better into the mesh opening during the flood stroke because of the increased screen pressure on the ink. The squeegee can also be allowed to go approximately 30% faster, because of the screen tension's very powerful screen snap force, as the squeegee moves across the image. The additional screen tension force will also force the ink to flow faster through the mesh openings and onto the waiting fabric, paper, or plastic substrate below.
