Question: As a beginner I am having hard time and sorry for this basic question.
I have bought some vector from ShutterStock and while removing the background layer, I get some black gradient in the edges of the sparkles!

For easier understanding, please see the image below.

How do I get a fully transparent image of the shining frame. [I have the layered vector file of the image]

Answer: 
The objects appear to have been *specifically* created to blend to a dark background.

You won't be able to *easily* alter that. But you *can* alter it.

You will need to select the objects with the dark coloring and adjust the dark color to white or to transparent. *How* one goes about that depends greatly upon *how* the artwork is constructed. It may be a simple matter of adjusting some color fills, or gradient color stops. It is difficult to state.

In some cases internal object construction may prove very intricate and difficult to change.

In *this art*.... Many of the objects are merely a gradient fill.

Select the object and change the gradient so that *both* color stops are the *same* color:

Then click the color stop that *used* to be dark and set it's *opacity* to 0:

Then do the same thing for *all* the other objects with dark in them - replace dark with same color, set that color stop to 0% opacity.

**The reason you need to set the color stops to the same color first** is because if you leave it as the dark color, you are going to get a dark drop-off of the gradient in the middle of it. Sort of a gradient from color to dark and *then* to transparent. Setting the color stops to the same color prevents this drop off when using transparency in a gradient.

Example of the drop-off if you fail to set color stops to the same color:

There are many suggestions to this but I think none of them will get you where you want. If you intend to use this flare somewhere else you don't have to convert into a transparent object. All you need to do is **copy and paste** it in front of the work you intend to **apply the effect** and make sure that **transparency mode** is set to **screen.**
