Hi guys,

I'm new here, hope we can share our knowledge together.
i've been trying to burn a screen with a film of 100 line per inch/screen, (very fine tone) using 500W spotlight. but it failed. the result i get all the time is not all the tone is successfully burnt out. it only gets 60-70% compare with the real pic. so any idea guys? help pls thanks!

what mesh frame are you using. If this is for t-shirts you are almost guranteed that you will need to drop your lpi to around 45 with the light source you are using.

Burning a 75 line screen on a 305-355 mesh frame with a 1500 halide is tough enough.

Hi fluid thanks for the explain.
i'm using 100T( i dunno how u guys count it in overseas) mesh frame to burn a 100 lpi film. if using 45lpi the tone will be rough. any suggesting lpi should i use to make a perfect tone on a white and black tee? thanks

thats the problem. Most screen printers use 45-65 dots per inch when printing. Only the big guys during industry awards boast that print at that small of a dot. I would use a 305 or 355 mesh frame for a dot that small.

Is this applicable for water base or plastisol ink? Thnks.
