I have an object with a clipping mask that contains a pattern. When I scale the object in Illustrator CC the pattern scales in the program but not in the print preview or actual print. I have scale strokes and effects selected in Illustrator, and have restarted both the program and my computer and the problem still persists.
1) if you double click the pattern swatch square in the swatch palette, it will resize the pattern down to the original size
2) in preference > general > you can select and deselect the "transform pattern tiles" check box
- SIDE BAR
you photo above looks like you actually just have an image of a pattern in a clipping mask.(that is not pattern in illustrator terms, that would be a background image)
- to make an image into a pattern, drag the image into the swatch pallete and use that as a fill.
