So you'll see a moiré when the two patterns are overlaid. But since the mesh doesn't get printed - just the image in the film - there shouldn't be a problem in the final print.Gordon Pritchardhttps://www.blogger.com/profile/15816064465006380641noreply@blogger.comtag:blogger.com,1999:blog-2596513120109522183.post-83064184819688797032015-05-07T08:12:06.150-07:002015-05-07T08:12:06.150-07:00Hi.

When the film was put on top of the mesh before exposure, a moire appeared. We rotated the film and found a spot where the moire disappeared. Would that possibly correlate to the 45degree angle you speak of with two patterns? Meaning, the screen mesh is one pattern and the film/artwork is the second Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2596513120109522183.post-48420048469614393242014-11-26T20:51:23.922-08:002014-11-26T20:51:23.922-08:00Check my previous answer on this post.Check my previous answer on this post.Gordon Pritchardhttps://www.blogger.com/profile/15816064465006380641noreply@blogger.comtag:blogger.com,1999:blog-2596513120109522183.post-69578327836738888602014-11-25T21:26:54.109-08:002014-11-25T21:26:54.109-08:00How about angle for special colors, spot colors an...How about angle for special colors, spot colors and pantone colors?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2596513120109522183.post-86096235539134580812014-11-18T22:45:57.889-08:002014-11-18T22:45:57.889-08:00It's rare that all 4 process colors will be pr...It's rare that all 4 process colors will be printed with a 5th color.

Everything goes pretty smooth, but at least once a week we seem to get some awful patterns in our one color jobs? Is there any recomendation for screen angles on one color jobs? From reading this it seems 45?
