Drop shadow cut-off after created pdf from Indesign 2023

but in the PDF output

Do you mean the problem is in the printed output? If the destination is an offset press, you might try taking the black out of your CMYK mix, e.g. something like 53|38|15|0 instead of your 35|21|0|26. The printable halftone dot size is limited for most offset presses, so in print the drop off from your CMYK color values to the white page might be more abrupt than it is on screen, and even more abrupt on the Black plate.

If the destination printer is some kind of composite digital printer, you might try using RGB swatches. Composite printers almost always use RGB drivers and do better if you send RGB color and let them make the conversion into the print space.

there is some cut-off above the drop shadow.

Hi @mani34374446to41 , Could you clarify or show what you mean by cut-off? I exported your test to the default PDF/X-4 preset and in AcrobatPro’s Output Preview the previews seem identical:

The size setting of your shaddow is negative. It should be 0 or positive.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
