Prepress: any tips for authorizing a PDF?

[Nermander]

A 4 page booklet may be one sheet, but it is two pages (one on each side of the sheet).

The specification references here says the file must have exactly one page, so there must be some misunderstanding between the OP and the printer. If it is supposed to be a booklet, they should not use this profile (which is only for one page).

I also find it very strange they do not allow both a Trimbox and an Artbox.

Yes, 1 sheet. My bad English translation.
"One page" thing could be head-to-head imposed pages so printer can print half run on double sized paper, then cut everything in half to get full number of copies.
As far as boxes, perhaps OP didn't put trim marks.

[Nermander]

As I said, they do not allow both Trimbox and Artbox, which is a bit strange since both boxes are allowed by the PDF format and the Artbox will in most cases just be ignored. The error message says there is both an Artbox and a Trimbox, and that would not have anything to do wit missing trim marks.

With a PDF, you don't need trim marks, because there is the Trimbox.

My impression is that the specification is for ads, but OP mentions a 4 page document. So either OP has ordered the wrong print, or the printer has misunderstood.

Well, my Prepress experience goes before pdf, as Postscript files for filming on Hard Disk, so I always put my marks & my color bars.

In this sense, being able to export from a Scribus .sla document all raster images WITH bleeds would be great !
And why not, being able to export a completely flattened .pdf into raster images (one image per page) (in alternative export solution).

Tips for choosing .pdf (a version that provides CMYK conversion if that's what's needed):

ISO 15930-1:2001: PDF/X-1a:2001, blind exchange in CMYK + spot colors, based on PDF 1.3
source : https://en.wikipedia.org/wiki/PDF/X

Ideally, always check with the printer which .pdf version is expected, also with which .icc profile it is appropriate to prepare your document (and whether it should be integrated into the export or not)

A good tool for analizing your .pdf online (for see majors problems) :

Note : for icc profil embeded with scribus, this tool always says : "Output Intents: Custom" with yellow alert
With Adobe or Affinity .pdf embed, wee see the exact icc profil version, and there no yellow warning but the green tick

There is also yellow alert
but ""Output Intents:" indicates for exemple with PDF/X-1a (from Affinity) :
"Output Intents: U.S. Web Coated (SWOP) v2"


If the printer don't want icc profil embeded, you must export 1.6 .pdf (for exemple) (in this case Scribus dont embed icc profil). Not export with pdf/x (who export always with icc profil)

Scribus is made to create print-ready PDF:s. If you want to convert these to raster images, you can use for example Ghostscript.

Fo sure.
But i can also export my document .sla in .png, .ico, .webp (raster images for web), or in .pdf for web (screen). And that's nice !
I don't know how to use Ghostsript.
I also can convert .pdf on raster images with gimp or krita (rigth clik open the .pdf with) and save them.
