Photo resist exposure Test Strip

[brosskgm]

Decided to start doing my own PCBs. Toner worked great. I decided to start using
negative photo resist. I've been getting different results and was told I want to create
a test strip to find the correct exposure for my setup.

Google doesn't seem to return many results with designs that can be used.

Does anyone by chance have a .lay file of a photo exposure test strip?

If no lay file negative picture?

Thanks
Bob

Thanks, but I was hoping the guy that posted one some time last year that I'm not able to locate would catch the post.

This is just for hobby exposure. I calculated the time/distance and they are doing ok. Someone mentioned
to find a test strip to be sure. They said there was plenty of DIY ones to use Google but that didn't return many
results.
