Bleed is there but printers keep telling me there is no bleed

You need three conditions:

1. In the InDesign-document make sure you set the bleed margins (check with Document/Document setup);
2. You will need to extend your elements to the red bleed guides you see on the page when you have set up your InDesign document with bleed (if you see no red guides around your page you did not set up a bleed!);
3. In the PDF Export dialog check 'Use Document Bleed'.

Your screenshot seems to be correct so maybe it is step 2?

Just as an aside, InDesign's defualt offset for marks is too small. You need to reset the offset to match the blled allowance to prevent marks from showing in the bleed area, and you can uncheck the Bleed Marks box in the dialog -- they never get used.

Your printer may or may not care about your registration marks, color bars, and page info, so ask.

Hi @Angela24925721ymjr , Did you check the PDF in AcrobatPro? Can you share a PDF the printer rejected?

Did you extend your images and colored backrounds to the bleed box or do they end at Page’s edge?

They must be extended to cover the bleed area.

Can you post a screenshot of a typical page showing the images with the bleed extending to the "bleed line".

Check with your printer that they do want Crop Marks, some don't want them nowadays.
