Here is another puzzle
A client sent us a 4 Sheet poster (60”x40:0”) all images in the poster are set to 300dpi and placed in the InDesign file at 100%.
When I made a pfdx4a file the pitstop preflight failed with ‘resolution of colour or geryscale image is less than 200dpi)
After placing the file in Neo, we could see that the offending images were from the Transparency effect on the type boxes.
After some investigation if you apply a transparency effect, Outer Glow, mode to multiply with black and if the technique size is set more than 25mm it generates the transparency effect as a 150dpi image.
does anyone have any ideas
