Hi Reese Jackson and Welcome to the Forums,

Could you attach the afphoto/afdesign or afpub file for this and which export settings are you currently using?

So from the looks of it i have to zoom in over 100% just to see it the correct way. any idea on how to fix it??

I am not sure exactly what you mean about the line changing, but I suspect part of what you are seeing is because while the yellow lines are perfectly pixel aligned, their widths are not even integer values, so when you export to PNG with Bilinear sampling the fractional pixel part of the lines are blended with the layers below them.

To see that their widths are not integer values, you can open Preferences > User Interface & set the "Decimal Places for Unit Types" for pixels to something greater than zero, like this:

(Note that this affects only the display of unit values; internally everything is done at the maximum precision of the app, which is to around 8 decimal places.)

Do that & you will see that the lines are actually nearly 2.5 px wide:

Of course, since you also applied a pressure curve, their widths can't be integer values over their entire lengths anyway, but if you want a sharp edge with no color change over as much of the lines as possible, one way to do that is to set the line widths to 2 px.

No that didn't help but thank you anyway. And what I mean by the line are changing is i place the line in a certain spot once i save it the line moves up a little bit.

 

Above in the first image that's how i want it to look but in Affinity Photo if i save in that exact area it looks like the second pic. So it can look like the first pic i basically have to drag it down out of site so it can save like it shows in the first picture. Now if I zoom in to maybe 150% it shows the correct way but in 100%  its off.
