How to use screen print on glass
Jun 15, 2026
In a piece of complete cover glass, you may wondering how the black borders, heating lines or logo to be located such precise. It's about the screen, imagine it looks like a super fine stencil.
What's screen role?
It puts the ink through a mesh on glass surface to build up the pattern layer by layer with correct thickness and edge quality.
Where you will find it?
Car windshields and sunroofs(Black edges, defroster lines)
Appliance control panels
Phone and tablet cover glass
Printed logos or patterns on building glass
What's the screen made from
Stainless steel mesh: The standard precision work, which holds its shape can last for a long time and gives sharp, repeatable results. It can be put in high volume orders worth to be trusted.
Polyester mesh: A lighter duty option, which is more affordable but not hold tensions after long runs. It suitable for simpler decroative prints.
What numbers we should pay concern:
Mesh count(Thread numbers per inch):
Lower counts(80~160) let through more ink, good for thick black borders.
Higher counts(250 or above) thin as hair lines and conductive silver paste.
Stencil thickness: Directly defines how much ink ends up on glass. The thicker stencil the thicker in layer.
What's a good screen?
Even tension across the whole mesh that print doesn't shift or distort.
Smooth stencile edge that lines come out clean not jagged.
Proper cleaning right after printing: The glass inks can dry hard and ruin the mesh if left too long.
What we should pay attention:
Tighter meshes for super thin circuit traces in smart glass and head up displays.
More use long lasting steel mesh with frames to keep tension steady, it's important when the print has to be within fractions of a millimeter every single time.
