3d help for packaging design

[jakerupert]

This time I have a pretty unusual question.

Its somehow from the field of packaging design.

 

I have to prepare an existing circleshaped 2D illustration to be able to be glued onto a reallife halfsphere smoothly.

 

So it will have to be distorted somehow and I wonder if AM could help me here to find out how this distortion

will have to look like and/or how it can be achieved.

 

Has anybody ever done something like that?

 

Any ideas that could be helpfull?

Can you give more information regarding how it will be printed or applied? Will it be distortion-printed on a vacuum-formed shape, or is it a shrink-wrap (like you see on a lot of drink bottles)?

I saw one of those 'How It's made' TV shows where they were making globes...with a map of the world adhered in the manner you mention. Maybe if you google or youtube search 'globe creation'.

Flatten a half-sphere, apply the decal, unflatten.

so I guess that makes it the shrink-wrap alternative?

Forget my previous suggestion.

 

Here's how...

 

a ) crop decal to the limits of the outer circle

 

b ) in Photoshop ... Filters>Distort>Polar Coordinates>Polar to Rectangular

 

c ) in Photoshop... double the vertical dimension fo the canvas

 

d ) in A:M New decal, application method>Spherical, Apply

 

e ) finished sphere (delete or hide the half you don't want)

 

 

 

 

 

 

If you really need the wrinkles a shrink wrapped image would get, you could drop a piece of simcloth on a half sphere.

Edit: forgot the decal...

 

[robcat2075]

Here's one with very dense cloth. I guess you could just find one sim that got the cloth to fall how you like it and then only need to edit the decal until it looked right.

Usually you do the art flat and undistorted as you like. There is specialized software for the flexo industry that will distort the art to correct it on the package. The factories most often have templates that you work in.

[jakerupert]

Thank you for all the very interesting suggestions.

 

I will prepare a circleshaped decal first and then wait, what factory my customer will find and what these factorypeople will say, they will need further from me.

One of the big programs used is called Art Pro. Took me a bit to remember but what it does is compensates the art for distortions. This makes the prepress very brainless considering the plate bounce, stretch and all the other nasty stuff that goes on in the flexo world.

 

Occasionally I have to distort art but that is usually for tapered mugs that use printed inserts, For the most part that can be achieved using envelope distortions, I use Canvas for most of the tough stuff, Illustrator, Photoshop and Quark for the rest.

 

If you do tons of vector work like I do, check out Canvas. Much of my work is fixing other peoples Illustrator CS files
