While your poster may be created in a vector graphic tool that allows you to endlessly zoom in with crystal clear clarity at the furthest zoom level, a virtual poster in EventPilot is converted into an image. Images that are not vector graphics have a limited resolution and will be compressed for smallest file size.
Ensure you create your poster graphic for on screen viewing with sufficiently large text, easily legible fonts, and clear graphics.
This article includes guidelines on creating/designing your poster.
