Rittagraf® professional screen printing screens are made with Swiss quality polyester mesh, certified by Sefar®.
The Sefar® screen printing mesh is glued directly onto the wooden frame. We are very demanding in our work so that our clients achieve top-level professional results. To ensure the best printing performance, our frames are covered under the strictest quality controls. The combination of frame size and screen printing mesh requires an ideal tension that is applied to each scrim. This respects the elasticity and properties of the fabric to achieve the best printing results in screen printing.
Wood frames with cross-frame assembly reduces the chance of frame bending and warping. Even so, wood is a material that is sensitive to changes in humidity and temperature. Small deformations in wooden frames are considered normal, especially in large sizes. This should not prevent correct printing and use of the screen. For very demanding works and superimposition of complex screens, it would be recommended to use screen printing screens with an aluminum frame.
43 threads is the standard number mesh for printing on textiles. The 90 and 120 thread screens are the most suitable for printing on paper and smooth and slightly absorbent surfaces. The 120 thread is the tightest and the one that offers the best definition. The 61 and 77 thread yarns are considered dual and offer us intermediate benefits between the extremes. They can be used with textile inks and paper inks.
The 43, 61 and 77 yarns are assembled with white mesh and the 90 and 120 with yellow mesh, with it we achieve better definition and detail in the profiles of the smaller images.
If we want to print with acramine ink, we can use 61, 77, and even 90 threads, but to achieve the best performance and opacity of the ink, we recommend using 43 threads to print water-based textile lacquers. The 90 and 120 thread count screens are excellent for printing our water based paper inks without fear of clogging the mesh.
Due to its quality-price ratio, we always have screen printing screens with wooden frames available in stock, but we also produce and offer screen printing screens with aluminum frames. Ask us prices and delivery times.
