Export to PDF sizing issues

[Xigma]

Hi, there an issue I am encountering. I am using Affinity Photo 1.8.5.703.

About a month ago I exported a file to PDF and the resulting size was around ~22mb. I then had to add an additional text line but the resulting PDF export size was ~350kb.

I haven't changed any settings/options/preferences.

In PDF Export Settings, I keep Preset: PDF (for print); Raster DPI: 300; Area: Whole Document

I haven't fiddled with the More settings last time nor this time.

Enclosed are some snapshots of the old PDF rendering close up of the vector fonts and the new one.

I have found the solution to one of the issues. The blurriness/rasterizing is because a HSL layer was sitting on top. Although the HSL was masked to perform its function on only a logo, I don't know why the rest of the document had to be rasterized. I brought the HSL down the stack but still no difference. Does the HSL layer do that?

Regarding the sizing issue, it still reads the same. I don't know why my previous export a month ago showed 22mb while now it refuses to go anything beyond 1mb. Although the output quality reads exactly the same.

The HSL Adjustment layer will affect, by recolouring, all the layers below it (or those layers below it within the same group that it belongs to) where the effect has not been masked off.
It will also affect, by rasterisation upon export, all the layers below it (or those layers below it within the same group that it belongs to), no matter whether those areas have been masked off or not.
In your document the HSL adjustment will cause everything under it in the Layers Panel to be rasterised (all but the three layers above it).
This may have caused the size of the PDF to drop substantially if, essentially, the whole page has been rasterised, but this would depend on how complex the page was in the first place.
If you only want the HSL adjustment to affect one particular layer (or group) then you will have to apply the adjustment to that layer (or group).
I hope this makes sense (and is correct).
