Create bottle label with projection

Dude,

I have just (re)created an improved version without external means.

Dude,

Just a follow up, with the way I should prefer to do it myself, in a more forensic geometric way without external means, in case you wish to consider that; it can be reused with small changes for other combinations of bottle and label sizes.

In the image below, I have made a bottle circle W = H = 400 and a label circle W = H = 360, 90% of the bottle width.

Smart Guides are your friends.

1) On the Artboard Draw the apparent label circle at full size with its centre at X = 0, then and add a number of equidistant vertical guide lines through it from side to side (including one through the centre), maybe 11 lines to give 10 intervals, 5 on both side of the centre, all lines extending a sufficient distance above the circle; select all the lines and create a copy below (Ctrl/Cmd+C+B) and Group them, turn them grey, and lock them;

2) Add a bottle size circle a bit under the top of the lines and align it horizontally with the label circle, then move copies upwards, as many as the guide lines to one side; also add dotted lines at the bottle sides; select all the circles and create a copy below and Group them, turn them grey, and lock them;

3) Add a label circle between the circels from 1) and 2) and a horizontal line through its centre; turn the circle grey and lock them both;

Duplicate the Layer, so you have the original Layer as a basis to fall back on, and for other combinations of bottle and label sizes, which can be made by simple scaling (uniform for circles, horizontal for lines); procede in the new Layer;

4) Cut the lowest bottle circle with the Scissors Tool at the intersection with the centre line and then with the first guide line to the right (Smart Guides say intersect when you are within snapping distance), then select the greater part of the circle and delete it so you have a path from the centre to the first guide line; you can see the full grey circle behind the path;

5) Select the following circles and do the same as in 3), only creating paths reaching each of the following guide lines to the right;

6) Select each of the guide lines intersected by the circle and cut with the Scissors Tool by clicking at the top and bottom of the intersection with the label circle from 3), leave the outermost guide line that only touches the circle uncut;

7) Select each of the curved paths from 3) and 4) and use the length from the Document Info to move the corresponding off centre guide lines outwards to that X value (the distance from the centre guide line); move the opposite guide line to the same negative X value (you may copy it from the X box in the Transform palette and add a -);

8 ) Delete the upper and lower parts of the cut guide lines; the original grey lines will still be visible;

Now you have a basis for the unfolded shape, which runs through the ends of the cut guide lines and reaches the intersection of the horizontal line and the outermost uncut guide line;

9) Create an ellipse and distort it in whichever suitable ways to get the best possible fit over the guides in 8); in the image below, I simply created an ellipse with the W = 447.784 (distance between the outermost uncut guide lines) and the H = 360, then with the Direct Selection Tool I selected both side Anchor Points and reduced the Handle Length to 78% (Object>Transform>Scale using 78% Vertical Scale) to get a quite reasonable fit;

You may print it out and wrap it round the bottle to see whether it is satisfactory;

10) Create/recreate the contents of the label similarly.

As you can see, the strethcing is increasing from negligible at the centre to distinct at the sides.

I approach it a little differently.  I would go and buy a few bottles of whatever beer has a round label on it.  I have an old school technique of removing the label using adhesive remover.  Using one of the other bottles,, I would take a digital pic of the front.  You do not have to, but this pic could be used as the "base" layer of your design ( remove all elements except the shape of the label and the bottle itself ).  Using the removed label, you could scan it  against a black background to give you the shape as "flat" which you could then build a "dieline" to be used to cut the label later.  Odds are you will need to warp whatever elelments you build on your "comp" ( your file that has the base layer of the bottle pic ).  You are essentially building a prototype of the entire design using a bottle with beer inside. So, so far, you have two files: 1.) one with a base layer of the pic; 2.) one with the label flat as a dieline.  When you get to the point where you have to generate a production file, the dieline will be put on a separate layer in the production file which will be flat.  The advantage to doing the dieline in the comp phase is the size and shape can be established and used as reference for your comp file ( which is a digital pic of the bottle and label shape as seen from the front [ of an existing bottle you bought at the packy ] ).  Also, there are two ways you could proceed: 1.) use the dieline file ( flat ) as your layout which can be presented or reviewed as printouts; or 2.) comp the 3-D bottle as your comp file to be preented later on.  Either way, elements can be copied and pasted to eachother, but the comp would be warped.  At some point you may have to cut the label and adhere it to a bottle.  The dieline file will work for that purpose.  Preliminary layouts could be printed of the comp file.  Whatever gets approved, you then build using the dieline file.  A few steps, but this would be my approach.  There really is no way that is correct or incorrect, it ends up being what you are comfortable with.  I can remember when we had to do markers by hand.

You are welcome, Dude,

I just completed the description, so it ends with 10).

Well, if the cylinder sections are circles, the intersection is a circle.

The label (before sticked to a bottle) can have the shape of an ellipse or when axis are equal, a circle.

Maybe your questions is how to and how it will look when sticked in a 3D bottle?

Is the 3D Revolve effect with a round symbol mapped what you want?
