Graphics distortion in thermoforming

[marcinito]

Once again hello,

Does anyone knows good resourse to learn about graphic destortion when it comes to thermoforming ?

could come from alot of different things, is the proper venting when you are forming, normally if there is not good venting around the graphics then they will show up not fully formed, maybe if you have a pic that you could show it might help to lead you in the right direction, between me and the ol man we have many years in the plastic extrusion industry, i am sure he has an idea if he sees a pic, PM me with a pic

I was refering more to distortion where you are trying distort applied graphic based on plastic shape that will change due to preheat and forming itself.
Imaginge 3ft dome with raised letters on it. Goal is to know how graphic needs to change before you decorate plastic face and form it. I found some info here : http://www.screenweb.com/content/an-...rtion-printing
