Blanket is over-packed causing a bump when striking the plate and jarring the form rollers. This creates a bounce and/or skid producing a streak
Tension blankets to press manufacturer's specifications
Streaks appear across the sheet one revolution back from the top of the plate. Ink form rollers are set too heavily to the plate or durometers are too high
Check durometer of rollers and replace if necessary. Set rollers to pressures specified by the press manufacturer
