Subject: Press'n'Peel problems

Hi folks,
 
New here. I'm Geoff from New Zealand. Have been doing PCBs on and off for maybe 35 years, first by resist-pen, then Bishop Graphics and Riston.
 
After a lull of many years  have now tried Press'n'Peel (blue) with a distinct lack of success.
 
Printing on Konica-Minolta C353 laser onto dull side of film. Good solid toner coating. Ironing onto nice shiny clean board at various temperatures, for up to 4 minutes. Film comes of leaving incomplete tracks on PCB, some toner and/or some thin remnants of the blue film coating remaining on film.
 
Don't know if a factor, but film was purchased over 3 years ago, so may be quite old.
 
Here are some pix of my results ( some of film after pressing, and some of pcb after press. Last pic is 3 patches done at the iondicated temperatures.

Grateful any suggestions.
 
Also, I see on YouTube others have tried a similar process using glossy photo paper, and soaking off - anybody here had with success with that method ?
 
cheers
