Blurry Printing

Drew

I have been working with the new Print Task this week and noticed that the end result is always a little blurry.
I have tested many formats (PDF, PNG32, PNG8, JPG) and changed the DPI (200 & 1000) in the ExportOptions object but nothing seems to make the map crisp.

I also tested the ESRI sample labeled "High Quality Printing" and it also comes back with blurry map images.

Has anyone else experienced this or maybe have a work around?

Thanks,

Drew

Instead of retrieving the tiles and stitching them together, the Print GP will make a /export map request to the service if it's a 10.1 service that has dynamic layers enabled on it. This will result in a new image being created from the data since /export will go to the data in this case. In all other cases, /export stitches the cached tiles together.

Dasa,
Thanks again for the reply. I was able to get our maps printing at a decent quality by doing the following.

Use a 10.1 service
Enable Dynamic Layers on the 10.1 service
Changing the dpi to 300 in the ExportOptions object
Printing to a standard 8x11 layout

I could have gone the high quality printing way as you suggested in your first post, but my application is mashed up with so many services it would have been a nightmare to manage all the replicated layouts.

Thanks again.

See this tutorial on how to print from the source vector data instead of cached tiles.

Thanks for the reply Dasa.

Just out of curiosity, why wouldn't the new Print GP service flip the Tiled map service to be a Dynamic map service to ensure there is not loss in quality. I assume it's speed but thought I would ask.
Generally most people should be using one Tiled map service in their mapping application and if the printing always results in a blurry base maps (due to scale change) it seems it would be better to render the Tiled service as a Dynamic service on the server side.

Anyways.. I am going to hack around to see what I can get going here with your post.. Thanks again,

Drew
