You need to specify whether to determine a match with how the degree of
similarity .

http://sikulix-2014.readthedocs.org/en/latest/pattern.html

excerpts from pattern.html:
Sikuli searches the region using a default minimum similarity of 0.7. This default value can be changed in Settings.MinSimilarity.
 The IDE supports adjusting the minimum similarity of captured images using the Preview Pane (internally in the script, the images are turned into a pattern object automatically).

example1(minimum similarity of 0.95):
if exists(Pattern("1442408970638.png").similar(0.95)):
    popup("Screen matches!")

example2(minimum similarity of 0.99):
if exists(Pattern("1442408970638.png").exact()):
    popup("Screen matches!")
