Affinity Publisher - Lines weight changed after export as jpg


Recommended Posts

Hi,

I'm working on making a journal page (300 DPI). When exporting my document as a jpg (best) the lines weight looks funny, some them look darker, and thicker. I have double, triple checked if in my document I have different size or the colors are different; nope everything looks the way it supposed to. I made the lines using the pen tool.  Don't know what I'm missing. I need your advice on how to fix this issue. Thanks

Welcome to the forum @Princess95

Seriously I really need to read better lol!

Why are you exporting as jpeg best?

It might be better to export as a PNG and or a TIFF file to maintain a better quality export, the file size will generally be larger but I think it would solve the issue.

As for why this is happening, it could be a viewing issue, so if you view the jpeg at 100% does it still have variable lines?

Hi @Princess95,

Welcome to the Affinity Forums :)

Could you please provide a copy of your .afpub file and the exported JPEG, so that we can investigate this further?

Are you seeing the issues in the exported JPEG when previewing the file externally, or are you importing the JPEG to Procreate, where you're then seeing this issue?

Many thanks in advance!

A quick look showed that you chose 0.3 points, that doesn't make a 2 pixel thick line. The minimum thickness you can have is 1 pixel and then you have to have the lines on the nn.5 pixel X location so it will be a pixel wide and not be antialiased. Then you can have a 2 pixel wide line and that has to be on the nn.0 pixel X location.

If you are needing to export to pixel format such as JPEG then you should design the document using Pixels as the Unit of Measurement and have Snap to pixels turned on and turn off Move by Whole Pixels. Even change the Preference to Uncheck Always show lines and type as points in Preferences > User Interface.

I have never mastered color management, period, so I cannot help with that.

I couldn't find the anti-aliasing setting, could you please tell me where it is located?

I don't know if Publisher has it, in Designer it's possible. A search on here will turn up help on that.

The thing is, turning it off will just move the problem - you'll have crisp lines but uneven spacing.

If you want it to look right, then as @Old Bruce has said, you need to create it differently.

Thanks for your file!

  1. I converted your document to use Pixels as the Units, rather than Inches.
  2. I used the Transform Studio to make sure all your lines were 'pixel aligned'
  3. I navigated to Preferences > User Interface and made sure 'Show Lines in Points' was unchecked.
  4. I selected all the Curve objects and set their width to 2px.
  5. With all the Curves selected, under Blend Ranges, I set Anti-aliasing to Force Off.

Now when viewing your document at 100%, all of the lines are displayed at the same width, do note when viewing at less than 100% zoom, Affinity uses Mipmaps to display the canvas, which may mean some lines appear thicker than others, but this will not be shown when exporting.

Please find a screen recording below showing these steps, alongside a copy of the edited file and my exported JPEG files after making these changes -
