Lines in video export vs image export

Hello,

I’m creating an animation that is made of thin black linework on a white background. When I export the animation as a video, the lines are very clear, quite thick and work well. However, when I export the animation as a series of images, the lifework is very thin.

I’m using Hidden line style and cannot change the line weight, even if I drag on another edge style under the ‘Edit’ mix.

Is there any way to export a thicken line weight with hidden line? (I can’t export as a video since proper animation doesn’t work. I’ve looked at keyframe animation as an alternative, but it doesn’t support parallel view)

Thank you

Did you find a solution for this, im testing profiles etc etc takes a while before i can see each adjustment
