White line, WHITE LINES!!!!

[norbinw]

How is this THE ONLY APP that gives white lines whenever I export something for print?

I have tried the same 25mm document at 300dpi in both photoshop and Illustrator, guess what?! NO WHITE LINE! Why is this happening in this crap app, always!! WHY do you guys think you know better than the customer, and make this shit default?? At least make it an option for the 5% people that use it. But hey! I'm talking to the same company that messed up bleed since 2020, and never fixed it :)))))

"But wait! there's a workaround, convert document to pixel, make integer number, convert back to mm and you are done. Basically waste 10 seconds of your life every new document, because our coders are lazy ass f*cks and think they are better than Adobe."

I have all the right to rant, as I have paid 2x for the apps.

I DO NOT WANT WHITE LINES, HOW DO I AVOID WHITE LINES FROM THE START?! I do not care for your pixel perfect shit, I want to avoid white lines from creation of the document. If the industry standard app doesn't give white lines, don't try to reinvent the wheel with Designer V1 or V2!

I wasn't able to reproduce your issue until I found out that the white line appears if you change the document units before export. So if you create the document in millimetres, it should stay in millimetres before exporting… If you change it, you'll get the line. This is not ideal, and I agree it should be an option in the export dialog.

The only other workaround I found was to export individual artboards instead of the Whole document… this seems to get rid of the line but obviously isn't the best solution since you'll have to compile them afterwards. So just maintaining the same unit is the way to go.

OK then, nevermind… I just tried a third time and now I am getting the lines regardless of the unit.  I am at a loss.

Yeah, wanted to comment about not changing units. I only work in pixels (online work) and mm (for print). Not changing units. For pixel units I understand it has to be on full pixels. But in print, I do not understand why can't the app just round up that half pixel!!! I have never required half a pixel in print, and if the "others" do it correctly, why can't affinity do it the same (or at least optional)??? It only makes me look unprofessional, as when you send it it mails, you clearly see a white line. Sometimes they even ask me what's up with the line?.. 

It happens because 25mm at 300 dpi equals that amount of pixels and a half!! 

I do not want to change units for every work I do and always correct artboards to be full values.. Half a pixel is useless, just round it up or down like the others!

Because in PS and AI, you'll never have exact 25.000000 mm. Internally, Adobe apps use other units (inch? point? I don't remember, my half-educated guess is points because it's the default PDF unit, and @ 72 ppi, 1pt = 1px), and all metric values are thus rounded. And slightly imprecise.

Whereas Designer allows you to use precise metric units without rounding, when needed.

Is it a bug?
I don't think so. Sometimes I would want to have all non-transparent pixels included on export if antialiasing occurs.

That's what obviously happens here.
Perhaps there should be an export option to switch from rounding up to full pixels (current method, obviously) to rounding down to full pixels.

Just my two cents.
Feel free to rant on if it makes you feel better…

And yet still the industry standard app is still industry standard and is widely used all around the world without issues. Serif again knows better than all uf us. Somehow Serif again, is "better than the others".. But then again.. Worse.. 

Round it up as round up the arttboard I am working on, not in the final export.. So at least I can see it before saving. Artboard is rounded up after export. 

Also, this app is so precise that 1x happens 1x not, just like Patrick mentioned :))) I've made another 25mm document an saved without white line.

As you've already alluded to, if you're working in pixels for screen based work then you'll be working with whole pixel document sizes and won't experience the issue, so long as you have pixel aligned your graphics and/or artboards if using artboards.

For your print documents, when exporting to PDF if your document contains multiple objects, group them together, select the group in the layers panel and choose Area: Selection Area from the PDF Export dialog window. If exporting a single object, select it in the layers panel and choose Area: Selection Only from the PDF Export dialog window.

For your 25mm x 25mm, 300dpi file, this will give you a 25mm x 25mm (or any other size) PDF file without the white lines unlike using Area: Whole Document which forces the exported PDF to use whole pixel values and is responsible for the white lines because you end up with a 295.275417px x 295.275417px graphic (25mm x 25mm @ 300dpi) sitting in a 296px x 296px document.

Using Area: Selection Area or Area: Selection Only will result in 295.275417px x 295.275417px (25mm x 25mm @ 300dpi) graphic sitting in a 295.275417px x 295.275417px document and no white lines.
