Example B Banding Caused by Misalignment There are two types of misalignment; vertical and horizontal. Refer to Test Pattern 4 ' page 6-14 for further information. Misalignment between two primary colors when creating a secondary color can cause two different effects: D If there is horizontal misalignment of the colors, it will create banding. D If there is vertical misalignment of the colors, it will create gaps or overlaps between colors (see Example C). Banding Problem 5: Problem Description: Corrective Action: Black, cyan, magenta and yellow columns are correct but banding in one, or all of the secondary color columns. This is an indication that there is a horizontal misalignment. Refer to Test Pattern 4 ' page 6-14 to troubleshoot the problem. Print Quality HP DesignJet CP Series Printers 6-11
