Export project with 2 spot colors to pdf with crop marks on both spot color plates

[mwenz]

There should be a registration color in Xara that by nature hits every plate. That is the only proper fix.

In lieu of a reg color that hits each plate, simply leaving the black plate on suffices to output the job. I've done film before that way. Due to any difference in line screen angle, I would avoid using the various pantone colors for the reg marks. Leaving the black plate turned on makes lining up the marks more accurate.

But as you see, the "printed" seps work. Which is what the OP was talking about. However, I have no idea how the words in the op "export" and "separations" even apply.

That should also be capable for those who desire to do seps in XDP.

I don't use XDP for such things. I'll do PDFX-1a (and would use PDFX-4 if/when available) composite pages, the crop marks, etc., hit each plate. But for on-page marks, the opening statement is what should happen.

Is is not because you are using spot colours in seps. that the reg. black is not coming through or did I miss something in the reading. Each place I worked have done things slightly differently in the way of setting out but most of them when producing let's say for a cheaply produced 2 spot colour brochure used manually placed reg. marks along with crop marks from templates. One shop which I disliked working in used shades of grey and pink to represent the spot colours but designing in this way was gross but that was the way the owner worked and the printer new the method. Not sent anything yet to a printer using PDF X-4 not sure if many printers really know what its values are yet and where to use it best. Think most printers run about 4 years behind the software if you think a few years and look at the way the handle transparencies.
