Hello dear collegues, what are the most common causes for horizontal streaks on the printed sheet for heidelberg speedmaster sm 102?
Maybe someone have kinda cheat sheet on where to look first, second etc. for this particular press. Like "case-cause-solution"?

if the image you posted is the entire sheet run in a landscape orientation then im not seeing a horizontal streak. I am however seeing a vertical streak. Please clarify.

Hello Andrei83,


The white unprinted area is the "GRIP EDGE" of the sheet ?


What are CMYK - Halftone % of the build ? and why are you using CMYK for a Black Image ?


Mark on the next picture you post of the BLK (build) the - Horizontal Streaks that you see !


Regards, Alois

id begin by either putting on a new blanket and raising the water a bit, or at the very least swinging the blanket around along with new packing to see if the problem area moves.

Hello Andrei 83,


So, this Streak appears at the same - x mm measure- from the Grip Edge on every CMYK Press Unit ?


Have you printed a sheet of individual CMKY Colours ?
