Hello,
If we place vector illustration, (EPS) to Adobe Photoshop as smart object - we can scale this illustration to any size we wish without quality loss and then save it in jpeg format, in desired resolution... This is great Adobe soft feature and it usually works fine, but recently i've faced a problem with some of my vector illustrations there - when i place those vectors to photoshop, it looks awful - iillustrations are jaggy, pixelated and very low quality... I'm using Adobe illustrator CS3, Adobe photoshop CS3, vector format - eps10.
What could be wrong there? Maybe i've made some mistakes drawing vector?
Example of vector with this error:

I'd be really grateful for some advices.

regards,
Lukas

Have you been doing anything different from the first vector files that worked fine?  Have you been playing with any filters, using transperancies, gradients, blurs etc? 

If I were you I would first go into CS3, open up one of the files that worked fine initially, save it as something else, convert it to eps and see if you're getting the same rasterising problem.  If not then I'd say there's some problem with your new vector file having some filter/transperencies/blurs etc.  If however you do have the same problem, then I would check your settings on converting to eps.  Check for instance that your resolution for rasterisation is set to 300 dpi.

Thanks a lot for advices, but i've found out, that there's other problem - illustrator from sellinggraphics.com told me what's the problem :

"It must be in the EPS format � you have to export it as pure vector, when I tried to do it, the result EPS file has around 60 MB.
If you use transparency or overlay modes, you have to change in EPS format settings the transparency section � click on Custom and set the Raster/Vector Balance to 100% vector. Otherwise the result will contain raster, that will pixelate in Photoshop."

After applying this option vector works in photoshop well.
