Title: Why Does Radial Gradient do This?
Post by: Dan_Wiedemann on October 15, 2010, 08:39

Hey there...

As some of you know, I'm starting with illustrations and I've been asking for help from time to time. Here I go again! I recently had this image rejected at Shutterstock because it contains a bitmap. After about 500 tests, I realized that the problem was in the 2 radial gradients. Although the file has more radial gradients, something in these 2 converted them to bitmap when I saved it as EPS10. The file somehow got accepted at Fotolia so you can have a look at the other radial gradients (middle top and bottom right)

(http://static-p3.fotolia.com/jpg/00/26/70/08/400_F_26700810_nMVhszL8kWKnLr0uj47eXd45Jg6fIzXv.jpg)

I've tried to explain a bit better the situation bellow. It works fine when it's a linear gradient. My question is: why?

I've also uploaded the EPS10 file to megaupload (http://www.megaupload.com/?d=QJ09EVP2) if anyone wants to have a look.


Thanks in advance!

Your eps file shows only the bitmap image, so I can't see the original radial gradient. Could you upload the .ai file?

I found that you can specify some parameters with radial gradients which do not work with eps files well. I had one case where the gradient was NOT converted to a bitmap, but when I reloaded the eps file the gradient had changed its shape.

Round gradients shouldn't have a problem, but I've heard when you stretch them or make them elliptical they may not be backwards compatible. This may be your problem.

Maui. Here is the AI file - www.megaupload.com/?d=ZLHA780P (http://www.megaupload.com/?d=ZLHA780P)

Cthoman - They are elliptical indeed. I just don't understand why round ones work and oval ones don't. Is it an Illustrator bug?

Yeah, it may be something else, but I remember reading someone else having the same problem on the Shutterstock forums. I assume the problem is that Illustrator didn't used to support those gradients in older versions. Adobe doesn't really intend for people to save in some ancient version disabling half the features they just created.

Yeah... What is up with that? What is the point of having new and magically amazing features if we have to use the stone age illustrator? When will  microstock agencies realize that this is the XXI century?

Yes, the problem is the elliptical gradient. No way around it, afaik.

If you want to avoid this in the future, you can reload the .eps file into Illy and use my ExtendedSelect script to check for any embedded bitmap image:

Thanks Maui... It's a shame it doesn't work, but thanks!

Wow! Thanks as well! I was looking for something like this for ages. For some reason, the one that comes with Illustrator CS5 doesn't work with me (Select - Objects - ________) and yours does! =D

The links palette works too for finding bitmaps.

Isn't it a bummer that everyone of the watermarks misses your illustration?  I have the same problem with my photos at fotolio.

True... I think fotolia should rethink their watermark. I have quite a few files that are unprotected there. At least it's the small version, so not much can be done.

Can't you use a blend instead of a gradient?

Using a Mesh doesn't raster too.
