Fault with printing PNG graphics

[NileshV]

After inserting PNG graphics into an Affinity Photo file, when I come to printing it's leaving a grey background. 

I have tried to save the graphic as a Jpeg and it prints fine. 

I could really do with the graphics in PNG to retain the transparent background.

Please see image attached.

 

Thank you

In Affinity Photo, is "Transparent Background" enabled in the Document menu?

If you're still having issues can you upload your .afdesign file or if private PM a link to download so I can take a look.

Hiya,

Thank you for your reply.

I've attached a file with two layers.

The top is the PNG image, the bottom is from a Jpeg image.

In Affinity Photo I have enabled "Transparent Background" in the Document menu; still no joy!

 

Thank you

Hiya,

Thank you so much for trying this. It's very kind of you to take the time.

To my eye there is till clearly grey parts on your printout; yes, no where near as obvious as mine.

As mentioned, when printing the graphic as a Jpeg it prints perfectly.

May I ask you to try and save, then print off as a jpeg, and then see the difference. There should be no grey at all. This is a watercolour wash made from blues and greens only.

I would be very interested to hear your thoughts after this test.

 

This issue also happens when using Affinity Designer. I also tried printing via Illustrator and Photoshop, no problems at all!

 

Thank you

Could you explain what you mean by ''inserting PNG graphics'? Are you loading them (File > Open), or placing them (File > Place), or Copy and Paste? This can make a difference even if your basic document has Transparent Background' set. I get the impression that you have started with paper images, and then scanned these in. It is these images (in which the background is not necessarily going to be white, or even uniform) that you need to set the background transparent. Did you do that?

You may like to apply a Levels or Curves adjustment so that everything above a certain luminance (that is your greyish background) becomes white.

Hiya,

The images are PNG format with transparent background purchased from Creative Market.

I'm inserting them (File>Place). 

I will try the curves adjustment.

Thank you for your reply.

Hi all,

This only seems to affect the Mac build, and not the Windows build. I have managed to reproduce it using a shape and some transparency and logged it with our developers for further investigations. 

For the meantime, you can try to print it from a Windows PC and it should be fine. 

Thanks,

Gabe.
