Resizing Logo Vector to Adapt to Different T-shirt Print Sizes

Do you have consistent scaling values for each shirt size? You can make an action for each size to scale, and center to artboard. You can then set the actions panel to buttons. If you have all your sizes in one document, you can make this one click to make all 5 sizes and position them.

LHtan,

As I (mis)understand it, your task is to scale up a logo made for an S size T shirt to sizes M - 2XL.

This may also include a positioning by you, especially since you mention "I'm working on a desktop-to-print role,"

Apart from the problem you mentioned, "PROBLEM: The logo designed for the S size T-shirt will be too small when it is printed on a 2XL T-shirt." there is also the complication that the T shirt proportions change with size, generally width growing more than length (and generally differently for different parts, but in this case there is no need to consider neck and sleeve).

Since you mention logo, and valid for most T shirt artwork, you obviously need to keep the proportions of the artwork.

The simplest approach is to simply scale up the logo by the Chest (width) measure, which will lead to its keeping the same proportion of the width.

That may be fine, but might be more obvious if the design is made to fit a size in the middle of the range such as M (maybe the one with the greatest sale), rather than one of the extremes.

Anyroad, this approach will lead to an increasing proportion of the length and of the entire front area, so another approach could be a weighed scaling by both width and height (maybe WxH to keep the proportion of area).

In any case, adapting the position of the logo/artwork is also important, and has to be done by someone.

One simple approach might be to centre the logo/artwork where the Chest is measured (more or less at the bottom of the arm hole), obviously depending on the width/height proportion of the logo/artwork itself.

If you put the design into a symbol and then have one file that contains symbol instances for all the different outputs, then you could just put your new design into that symbol.

You could also do it on output if you output it in SVG, PNG, or JPEG via the Export for screens function.

And there is a script by Sergey Osokin that scales artwork to the artboard size. So if the design proportions are the same, you mabye can use that. https://github.com/creold/illustrator-scripts/blob/master/md/Item.md#fitselectiontoartboards (FitSelectionToArtboards)
