What mesh count should I use for halftones?Updated 4 days ago

When printing halftones, selecting the proper mesh count is critical for holding fine dots and producing smooth gradients. A good rule of thumb is to choose a mesh count that is 4–5 times your halftone line frequency (LPI).

For example, if your artwork uses a 45 LPI halftone:

• 45 × 4 = 180
• 45 × 5 = 225

This means a mesh count between 180 and 225 is ideal. If you have a high-quality exposure unit and your process is well dialed in, you can often achieve excellent results on the lower end of that range. If you're newer to screen printing or want a little more insurance that the halftone dots will hold properly, a 230 mesh is typically the safer choice.

You can also work backward to determine the maximum LPI a screen can reliably hold. Simply divide the mesh count by 4 or 5. For example, a 230 mesh is well suited for halftones up to approximately 46–57 LPI, depending on your equipment, emulsion, exposure, and printing technique. While this formula is a great starting point, your exposure quality, screen tension, and overall process all play a role in how much detail your screens can reproduce.
