Hi,
it would be very helpful to get a PDF/X-3:2002 (1.3) export option. Like it is still available in InDesign CC.
When working with small printing (also large ones) companies they often support / prefer this old standard. Because if the transparencies are flatten they have less problems.
Yes, they want to use their "old" software. In the ever-shrinking print world they have problems out of the costs. A Software update would not pay off for a very long periond of time.
I don´t need this type of PFD files very often, but with my last two projects I have had exactly this problem. Searching the internet it also turns up very often.
Also here in another topic:
Would be nice to see this option in on of the upcoming updates.
Best, Thomas
