Just an update on this. We tried using a 200lpi round dot with this customer. The irregular dot structure dissapeared but the print was extremely flat. Even with dot compensation curves etc. We can not continue using the 200li round/square dot as it definately creates print problems. It appears as if it is mottling on the press. I have now had it at more than one customer who uses the same dot structure and line screen. We have now taken them down to 190lpi which seems to be a standard screen set for this supplier and now the dot is not irregular anymore. We are though having a situation where the print looks a bit flat. It seems to have somehting to do with the midtone areas. Any more suggestions?
This might have less to do with the dot shape/lpi and more to do with tonality. What are you targeting for tonal response and how are you attempting to achieve this?
