: Why does blend smooth not work perfectly for two black objects? Here's what I did in Illustrator CC 2015: Typed a letter i Clicked Create outlines Selected the circle and below part of shape

Blending from black to exact black with smooth color seemingly doesn't work. If you still want it, try as a workaround 3D effect Extrude. It can give to you even more, if you use some else shape color than black. See the following examples:



Even full black shapes can have shading if another shading color is selected than black (=default).

Another workaround is to have blending option specified step or specified distance selected. If you have distance = 1 pixel, you probably get at least onscreen smooth blending. The number of intermediate objects can be hundreds, but if the objects are simple, there probably is no fatal slowdown.

The following example is a flat shape that has a modern long shadow. There are 2 versions. In the upper one the shadow is a blend from solid black to fully transparent black. It a little resembles a shaded extrusion. The blending is made with specified step = 1 pixel.

The lower has a 3D extrusion which is expanded, united to one shape and filled with a gradient from solid black to fully transparent black. There's no shading to keep the result flat.



3D doesn't generate that much copies of an object. After expanding and uniting there are only 2 perfectly flat objects (i body and the dot).Unforunately the expanded extrusion often needs some tweaking to make it fit with the original flat shape, because the profile is skewed in the extrusion.

By default, Illustrator's Blend is set to Smooth Color. This creates a blend between the color of the first object and the color of the last object.

If there is no color variation, Illustrator's Blend default to Specified Steps.

So to answer.. black to black is a specified Steps blend. Black to any other color is a smooth color blend. You can alter this setting by selecting the blend object and choosing Object > Blend > Blend Options.

Regarding the edges - Blends are essentially a way to iterate between two or more shapes, creating a copy based on X% of shape 1 and X% of shape 2. Blends never create a "smooth" edge. Blends create copies and just like manual copies, some things like square corners on an angle will always create a "stair step" appearance. You can diminish that stair-step by increasing the number of steps, but it will never really be fully gone.
