Thanks much Johnson for reply
and sorry i reply late because i have been in offline due to i had been in hometown and no computer there and just back hostel that can online. I attach the positive and negative films as here, but i only know how to use eagle to print positive while have no idea for negative film. My routes are bottom layer only to be printed.
I need do negative film because my school only allows PCB fabrication for negative and i know using positive film requires PCB and developer different than negative. Thanks again Johnson.
