Designer - How delete semi transparency?

[Insane_Fox]

Is there some trick how chance all semi transparent to full transparent or solid color? Or make it in exported img? Some lines what I use have some transparency effect but I cant have it for shirt printing.

Are the objects vector or Raster images?

[Insane_Fox]

Raster image. I use chulk lines.

[Insane_Fox]

@firstdefence Its raster.

Hi sorry the delay in replying, just got back from working away....

In Affinity Photo there is Select > Alpha Range > Select Partially Transparent.

@firstdefence I have designer only.

You can apply a Curves Adjustment to the alpha channel to perform a threshold adjustment of the opacity/transparency.

Perhaps exporting as a JPG would work, as JPG files don't support transparency?

My way to make semi-transparent (excluding full transparent)

1. add levels adjustment
2. choose alpha channel
3. set white level to 0

This boost all non-zero alpha values to 1, but keeps 0 as 0

To get all fully opaque:

1. add levels adjustment
2. Choose alpha channel
3. set output black level to 100%

Note that black will be used as color for formerly fully transparent areas.

 

if you want to choose your own color for formerly transparent areas:

1. add a rectangular shape on size of document or artboard
2. set color as you like
3. Move at bottom position in layer stack

You can combine both, methods, this will allow to use existing colors for semi-transparent areas, and use a specific color for fully transparent areas. But then you might need to group existing layers and nest the levels adjustment to the group, but place the rectangular layer below the group (not into group)

Hi,

This worked amazingly! ⭐️⭐️⭐️⭐️⭐️ Can I ask, what colour does this make pixels that are semi-transparent?

Thanks.

There are many ways. You can set opacity directly in color panel, or indirectly.

• If you start with an empty pixel layer, and use a soft brush, either by the brush itself or by setting hardness to e.g. 50%
• by setting the opacity in color panel below 100%
• by reducing layer opacity, or fill opacity in layer fx or blend range
• by using erase brush with a soft brush
• by adding a mask

the color panel, brushes and layer settings allow all to reduce opacity, individually or combined.
