Line artifact in render? When I render (and in render preview) I get shadow looking line artifacts. I suspected the texture at first but removing the texture in the material it's still there.

Here you can see the artifacts starting in the "Note" and "Volume" text and heading up to the right corner of the mesh. 



I don't have any bump map, just a simple texture. Changeing the lamp (type and/or angle) doesn't make it better.

PS. Yeah you guessed right, I'm a beginner with Blender. :D
It's hard to tell the exact problem here without a blendfile but it seems like you used ngon's for the mesh (polygons with more then 4 vertices). For hard surface modeling this is usually fine but it can lead to artifacts because cycles converts them to multiple triangles. here this might mess up your topology when many triangles (that are generated because of the holes for the buttons in the mesh). One simple thing you could try is to make sure your plane is completely flat. just select the whole plane and press S+Y(or X- depends on how you rotated it earlyer).+0
