Thanks for that Peter.
I've just been playing around with those instructions with mixed results.
- When I have the setting as recommended on that page: raster/vector all way to left, linework at 600 and gradient at 170 the boxes disappeared! But my grey became blue and the text became 'fluffy'.
- Next I changed the settings to be raster/vector at 25 (one notch to the right), line art at 1200 and gradient at 300ppi which results with the boxes back.
- With raster/vectors at 10, line art at 1200 and gradient at 300 it worked pretty well - text is clear and boxes around logos gone, but that box ghosting that was happening is back but set randomly on the page and the first few letters on each line have a slight kink in them (like the line moved down halfway through the 2nd letter)
- The above result also happened with raster/vectors set at 5 - this seems to be where the difference is made.
Have you come across another way to solve this issue?
I feel like it must be a common occurrence with magazine and book publishing not seeming to have this issue?
Thanks so much for your time! Its really appreciated
It's less of a problem these days on commercial presses as the industry moves away from the older bi-level RIPs.
I would try exporting PDF/X-4 and print that to see if you get better results.
