During takeoff/climbout (200') we entered wake turbulence from a 757 in front of us. The aircraft rolled to the right and we continued to climb just to the right of course. (0.18 was shown on the MFD). Winds were 150/07 and we were LNAV to RONII. Before getting back on LNAV track; ATC assigned us to a left turn to 070 and stated we were south of our track. In the next transmission; we stated what had happened (wake turbulence) and the Controller cleared us to continue the departure.
Reporter stated he has noticed ATC departing aircraft with reduced spacing to B757 aircraft; resulting in more wake encounters.
