In other words, if rgb is permitted and transparency is supported, is this acceptable? Julian On 18/5/25 19:06, Pablo Rodriguez via ntg-context wrote:

[...] I guess my question can be reduced to something very simple: is the result above acceptable for sending this pdf/x to a printer, given that we are printing only in BW/grayscale and that IngramSpark insist on pdf/ x-1a? In that case, how about the following?
\setupbackend [format=PDF/X-1a:2001, intent=sGrey-v4.icc, profile=sGrey-v4.icc]
Not sure whether this makes complete sense, but both you color profile and your output intent are grayscale.
