Why Do Sawtooth Edges Appear When Silk Screen with Printing Mesh

Printing mesh used in silk screen art is a material that applies vivid patterns to a variety of objects. Yet, printers often encounter a vexing issue—sawtooth edges that mar the design's crispness, directly affecting the saleability of the final product.
 
This flaw in the screen printing process can be attributed to various factors, particularly related to the intricacies of the printing mesh utilized. At MAISHI, we're not just experts in manufacturing screen printing mesh but also in providing solutions to the technical challenges faced in screen printing. Within this narrative, we delve into the causes of this problem through the lens of the printing mesh.
 
Sawtooth edges in prints generally point to poor ink transfer through the mesh openings, a challenge intimately linked to the mesh count. Coarser meshes allow for larger openings, graphics edges are difficult to form and lead to unsightly sawtooth edges. For example, when printing with a 15T (38 mesh) or 24T (60 mesh) screen, the edges of the print may exhibit a sawtooth edge appearance. To create smoother edges for the printed pattern, one might consider using screens with a higher mesh count, such as 36T (90 mesh) or 43T (110 mesh).
 
Additionally, we can also adjust the angle of the printing mesh during the screen frame-making process according to the level of detail in the pattern, which can effectively improve the edge conditions of the graphics. For instance, the printing mesh can be fixed in the frame at an angle of 22.5 degrees.
 
While other factors such as ink quality, screen tension, and emulsion thickness play their parts, they require separate, in-depth discussion.
 
MAISHI possesses a wealth of experience with a vast array of printing mesh counts available, from 6T (15 mesh) to 165T (420 mesh), ensuring a robust inventory for prompt delivery. Let's join hands in striving for excellence in our screen printing ventures. Welcome to the MAISHI team for more technical support and advice on choosing the right printing mesh for your applications.
