Export for DTF print with transparent background but no semitransparent pixels

[Ondrej Pelikan]

Hello,
I need to create a large sheet of graphics for my DTF printing supplier.

The file is a mix of vector and pixel graphics.

For pixel graphics, I use PNG files with no semi-transparent pixels—just a fully transparent background (0% opacity) or fully opaque areas (100% opacity). This setup works for DTF printing.

However, I’m having trouble exporting this mix of graphics while maintaining no semi-transparency:

If I export as PNG, the vector graphics get semi-transparent borders.

If I export as PDF, the PNGs get semi-transparent borders.

My current workaround is to export as PNG, then manually edit the file to remove the semi-transparency using curves and alpha adjustments in Affinity.

Is there a way to export as PDF to keep vectors as vectors without altering the PNG border (and keep it 0% or 100% opacity)?

Try this

Select the object
Click the cog
Change Inherit to Force Off

Or you can group layers and alter the cog setting for the group which affects all the individual objects, text whatever

If you use one vector layer (rectangle in document size, no fill, no stroke, artboard, or Layer layer) or a group as top level, you need to only set antialiasing to off for that top level layer, as all child layers will inherit the settings (which is default for all newly created layers).

I don't think I would have thought of that. Thanks a lot.

Maybe I'm doing this wrong, but it doesn't seem to work that way for me (Mac Ventura, Photo v2.5.5).

I have a Photo project that is mostly pixel based (includes one stripped pixel image with a clear background). I have one vector triangle above the pixel layer, Antialiasing set to Inherit. Above them all, I added a rectangle shape, no stroke, no fill, and set Antialiasing to Force Off. Both the lower layers show antialiasing no matter whether the top rectangle layer is set to Inherit, Force On or Force Off. I can adjust each of the lower layers to Force Off and that works for that layer, but not the layers beneath.

In Designer, if I set the Altialiasing to Force Off on the Artboard, then the layers beneath Inherit Force Off (when set to pixel view mode). 

Does this work in Photo, or just in Designer? What am I doing wrong?

I think I figured it out. "Inherit" only appears to work on Child Layers of the Parent. If the Parent Group, Artboard or Rectangle Parent is set to Antialiasing: OFF, and the child layers are set to Inherit, it works.

Antialiasing setting doesn't seem to propagate to layers below that are NOT part of the parent.

I had a ginger-carrot-soup for lunch while writing my reply. How did you know?

That seems entirely reasonable! You wouldn’t expect your personal attributes to be inherited by other people’s children, would you?

In human parent/child relationships the father is always putative, but in software??
