wrapping a graphic around a cylinder... perfectly...
« on: June 29, 2012, 09:33:15 pm »
Hello everyone,

Perhaps a simple question, but I just can't seem to get the solution I want. 

I have a 47.5" tall cylinder, and an illustrator graphic (full bleed, appropriate measurements) that I would like to wrap around the cylinder.  The graphic is 47.5" x 25" and should wrap around 3 times completely.  I have exported it as a jpeg.  When trying to apply the texture map, I have used box, spherical, cylindrical, planar x, y, z... but they all give odd results without proper scale and alignment.  When I try to tweak the adjustments, I'm still getting horrible results. 

If you had a cylinder, and an image spread that you needed wrapped around it three times (side-to-side), how would you proceed? What am I doing wrong?

While typing this, something clicked.  I made a new illustrator document, with all three decals next to each other, in a side-by-side fashion.  I then applied this, with the cylindrical tool.  Wouldn't you know it?  It worked. 

I'm still having a problem getting black text in my decal to show up.  Red text, and red graphical elements show up... but no black text.  Any thoughts?

So by wrapping around three times are you trying to ultimately layer 3 images on the cylinder atop each other?  Or are you trying to create a spiral effect like a barber pole?  It might be helpful if you could show a visual of the cylinder and the texture map you're trying to apply.

If you're applying these as decals or as Keyshot calls them "labels", Keyshot allows you to add/layer as many labels as you want. In this case I recommend exporting your Illustrator artwork to Photoshop and then re-exporting them as .png files with transparent backgrounds . Make three separate files versus trying to wrap it three times. Note: it is important that your Photoshop file image mode is set for 8 bit RGB for the transparency in the .png files to work correctly. This is typically default for new photoshop docs.

If you're trying to create a spiral effect like the barber pole, the spiral effect has to be part of your "flattened" decal. The cylindrical mapping tool doesn't allow you to wrap more than 360 degrees. You can wrap 0 to 360, and you can scale and repeat the texture within those ranges.

Hope this helps!
