Backing Support strengths Carbon
The RKS Carbon S HQ squeegee are purposefully produced with backing support thicknesses of 1.2 mm, 1.7 mm and 2.5 mm.
RKS has managed to bring the present state of the art, the mechanical strength, the required flexibility, and solvent resistance together with abrasion resistance to the best possible mixture.
Before now it was difficult to keep to production times ashdown time was difficult to predict this is made easier with the use of the RKS squeegee.
The Carbon S squeegee requires less contact pressure than conventional squeegee. The stencils are put under less stress and the overall mechanical stress on the printing machines can be reduced.
The different carrier thicknesses of 1.2 mm, 1.7 mm and 2.5mm, offer the individual user the possibility of adjusting to the desired flexibility and maintaining squeegee pressure and maintaining print specifications.
A 1.2 mm Carbon S blade offers more flexibility than, for example, a 2.5 mm "thick" Carbon S blade which then far more inflexible, and so has an excellent recovery strength.
To put it simply the more rigid the carrier the finer the line print or lower print/paste thickness.
Polyurethane Strengths (print edge)
The Carbon S HQ blades are produced with polyurethane thickness of 3 mm, 6 mm and 8 mm.
As with the selection of the various carrier support thicknesses, the thickness of the polyurethane and its flexibility the requirement is often completely different, although the printing applications are very similar.
While an 8 mm thick print edge still represents is very flexible and so provides a higher lay down of paste / ink ware as a 3 mm thick much more un-flexible thereby allows a lower pastes / ink lay down.
We generally see the different carrier support thickness and variable polyurethane widths a form of "fine tuning" in precisionscreen printing, this is regardless of the selection of the appropriate Shore -hardness.
