kcb Posted June 25, 2018 Share Posted June 25, 2018 I am trying to create a seamless pattern in Affinity Designer. However, when I got to place my tiles (squares with pattern inside) next to one another I end up with very thin white lines between the tiles even though they are placed exactly next to one another. Is there a way to get rid of these lines? Some articles I have read mention anti aliasing being a problem, but I cannot find a place to switch this off in Affinity Designer. Any help would be much appreciated. pyxelles 1 Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted June 25, 2018 Staff Share Posted June 25, 2018 Hi @kcb, Welcome to the forums. Can you please send us a screenshot or the .afdesign file so we can have a look? Thanks, Gabe. Quote Link to comment Share on other sites More sharing options...
kcb Posted June 25, 2018 Author Share Posted June 25, 2018 Hi! I will attach them here. I hope you can seem them, they are most visible down the middle of the tiki hut graphic. In the screenshot with two artboards, the image on the left is my tile and the image on the right is the tile repeated to make the pattern in which I am getting these residual lines. Thanks so much for your help. Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted June 25, 2018 Staff Share Posted June 25, 2018 Did you definitely snap the edges? Can you please attach the .afdesign project file? Quote Link to comment Share on other sites More sharing options...
kcb Posted June 25, 2018 Author Share Posted June 25, 2018 I've tried turning the snapping on and off to see if it made a difference...didn't seem to work DigitalPaper_TikiBirds.afdesign Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted June 25, 2018 Staff Share Posted June 25, 2018 I'm not too sure how you got that gap. On the screen, it's more likely a redraw / view port artefact , because the seam it's not present in the export. Make sure you check Snapping, Force Pixel Alignment and Move by whole pixels.

kcb Posted June 25, 2018 Author Share Posted June 25, 2018 I suppose as long as it's not visible in the export I can live with it. Thank you so much for your quick responses and help with this issue! Quote Link to comment Share on other sites More sharing options...

PixelPest Posted June 25, 2018 Share Posted June 25, 2018 Unfortunately the AA issue will make it into PDF:see above. (Sorry but no text entry box appeared in first place.) Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted June 25, 2018 Staff Share Posted June 25, 2018 If you re-arrange them with Snapping, Force Pixel Alignment and Move by whole pixels on, the seam will not show up. Support.pdf Quote Link to comment Share on other sites More sharing options...
PixelPest Posted June 25, 2018 Share Posted June 25, 2018 I rearranged in first place with the settings you mentioned before I checked and when I take your PDF and open it with macOS Preview.app and look at it with the magnifier I still got this: Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted June 25, 2018 Staff Share Posted June 25, 2018 Must be something from your end. Neither Mac nor Windows show a seam. I would recommend opening the pdf with a proper app, not with Preview. Quote Link to comment Share on other sites More sharing options...
MikeW Posted June 25, 2018 Share Posted June 25, 2018 If in Acrobat's preferences I have Enhance This Lines on, there is no issue. If that switch is off, then at some zoom levels I do see the stitching lines in your PDF, Gabriel. This is not generally an issue in print.

PixelPest Posted June 25, 2018 Share Posted June 25, 2018 This is odd, because when I open your PDF in Affinity Designer the upper middle top part is made from one shape - of course there´s no gap, but it´s stacked from many parts as you can see: Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted June 25, 2018 Staff Share Posted June 25, 2018 That's how OP's designed it. Quote Link to comment Share on other sites More sharing options...
MikeW Posted June 25, 2018 Share Posted June 25, 2018 Then AD is adding elements that are not there. This is editing that PDF of Gabriel's in Acrobat: The same number of elements occur in all my other applications...but I didn't try AD.

PixelPest Posted June 25, 2018 Share Posted June 25, 2018 I believe it´s depending on how it´s built. It seems the shapes are drawn in a whole but got masked to half at the seam by an Artboard feature. Quote Link to comment Share on other sites More sharing options...
MikeW Posted June 25, 2018 Share Posted June 25, 2018 Oops. Yep, I was wrong. I can uncrop them in Acrobat. Quote Link to comment Share on other sites More sharing options...
kcb Posted June 28, 2018 Author Share Posted June 28, 2018 So I have been playing around with opening the exported jpg files in many different programs but I am still seeing seams! They are more faint, but still there. They appear and disappear when I zoom in and out, but I cannot have that be an issue. I'm VERY frustrated. Can you please help me resolve this? Being able to create seamless patterns is now a requirement for the work that I do. According to my research around the topic, this can be an issue when creating seamless patterns in Affinity and Illustrator, the solution people suggest is to turn off anti-aliasing, but I cannot find a way to do this in Affinity Designer....

kcb Posted June 28, 2018 Author Share Posted June 28, 2018 I am very frustrated and trying to get some help resolving an issue with creating seamless patterns. No matter what I do in exporting, adjusting snapping, etc. I am getting white "seams" on my screen. Sometimes they disappear when zooming in or out or may get more faint, but they are there in my exports regardless. I do not understand what is causing this issue. To prove that this is indeed a program issue I performed the same operations in a trial version of Adobe Illustrator and experienced no issues - there were no visible seams in the working document as well as none in the export. I would very much like to stay with Affinity as I have otherwise had a nice experience, but this might be a deal breaker for my new work requirements, can someone please help?

MikeW Posted June 28, 2018 Share Posted June 28, 2018 All your artboards are fractions of a pixel off, all in one direction, many in the other direction. Change the document units to pixels. Click on each artboard and change the X/Y values to be whole pixels. Try that. Alfred 1 Quote Link to comment Share on other sites More sharing options...
MikeW Posted June 28, 2018 Share Posted June 28, 2018 So the tiles should be correct now. But they will need to be corrected on the artboards as some are off in their placement. Quote Link to comment Share on other sites More sharing options...
gdenby Posted June 28, 2018 Share Posted June 28, 2018 When I open the file on my Mac, I see no faint lines at any level of zoom. I do see that the art boards are not positioned at integer pixel values, but I cannot see any change when I reset the position to integers. There is a known screen rendering problem when shapes w. the same color are side by side, but those don't render in exported files for print. But again, I'm not seeing that at all from the start.
