Maintain Those Layers
Over the years, layers have become the crucial organization and management tool of both Photoshop and Illustrator. Although layers have been available in both applications for years, the ability to import and export layers between the two didn’t show up until recently. Let’s continue to look at the Photoshop Export dialog and the options that relate to layers.
Selecting the Write Layers option will export each top-level layer as an individual Photoshop layer. If you have built your artwork using sublayers, also known as nested layers, you may also want to select Write Nested Layers (see figure 3). Doing so writes top-level layers out as Photoshop layer sets. Otherwise, your nested layers are flattened into the top-level layer. If the option to Write Nested Layers is unavailable, it’s a telltale sign that your document isn’t currently using nested layers.
Figure 3: Sublayers live under your top-level layers in Illustrator. Be sure to have this option enabled in the Layers options.
If you find the resulting Photoshop file unexpectedly merges or drops layers, try isolating any blend modes you’ve applied. Select the objects in question and in the Transparency palette click Isolate Blending (see figure 4). If you’re not happy with this effect, try applying the blend mode overall to the layer if possible.

Sorry but I don’t comply to this article. The Export function in CS2 Illustrotor is just a buggy crap for me. Most times it exports the first objects from the top into separate layers but it merges lower layers and objects into one layer regardless if you put them into separate sub-layers before or if you marked them for “Isolate Blending”. And it’s irrelevant what trick can preveal it from merging. The whole function simply doesn’t reach it’s aim: a PSD file with layers and layer-groups just as it is in illustrator. Quality software is different.
What is recenced as “the Photoshop Options export dialog” is in fact the illustrator export dialog box.
