bleed AI

[Jan373823687ed1]

Hey,

im working in a small printing shop for our university, and userdata for printing which arrives me is mostly unproffessional, with no bleed at all.

Yesterday I used Photoshop to extend an image with AI to have a bleed area. What a glorious idea! And I wonder: Is this scriptable for InDesign?

As a quick v0.1 version:

• Only works with image-containers
• Shows a dialog for how much bleed to add
• (Hands image to ps, ps extends, image is placed again, container has to be extended by the ammount of the dialog

v0.2 

• reads bleed from document-settings, only throws a dialog if no bleed is set

vX

• doesnt care if selection is no image, and instead exports the page

Hi @Jan373823687ed1, this is a great idea for a script. It seems to me that it is achievable, providing that in photoshop you can script the generative fill, which I have no idea about. Maybe ask just that part in the photoshop forum.

I'll tag @rob day who is very clever with BridgeTalk to get Indesign to talk to Photoshop. Or is there a modern UXP way to do bridgeTalk's job now days?

Anyway, cool idea. I hope someone can help you progress with it.

Hi @Jan373823687ed1 , I use the script below for fixing InDesign page items that are not bleeding—it doesn’t adjust images.

You can use BridgeTalk to open linked images, but it can be difficult coding and there isn’t anything in the Photoshop API that would make AI adjustments, so you would probably  have to build an Action and trigger the action with a BT script.
