I've got a problem with a large format banner I'm having printed, where a gradient created in InDesign is banding. The printer is telling me that InDesign gradients are not acceptable and to recreate them in Illustrator or Photoshop before making the PDF.
Can this be right? He claimed InDesign uses less steps in creating gradients which is what causes the banding. I've done plenty of large format work and never some across this before so I'm hoping to find some sort of evidence that they're telling me porky pies. I'm guessing they just have some crappy rip software.
I'm on CS5 if that's relevent. Thanks for any advice.
