Thank you for the quick response!

I tried brightening an image within Scribus with Image Effects, however, as a result, the "out of gamut" marker colour was brightened as well ... I totally did not expect this.

I can of course edit each image in Gimp, though I'd prefer not to (does Gimp preserve the embedded colour profile? I vaguely remember having issues with creating images with non-sRGB colour profiles in Gimp before)

I also played around with rendering intent, but none of the given options resolve the out-of-gamut issue.

I am not very good at color management, but I have read a lot to try to understand it.

Out of gamut means that the color cannot be reproduced by a printer using the selected output profile.

Since you mention the darker colors, my guess is that printing these with CMYK generates more ink than 300% per pixel. If that is the case, brightening the images could maybe help.

Also maybe changing rendering intent may help. If it is a comic book, maybe you do not need to use perceptual (which is mostly useful for photos, if I understand right).

Hello!

I'm new to Scribus and DTP and running into trouble with colours that are out of gamut in imported images. I've searched the forum for "color management" and checked the corresponding Scribus wiki page, but I couldn't find a solution to my problem.

What I'm trying to achieve is the following: I'm trying to create print version of a comic I bought digitally (private use). The comic is originally in PDF format and the images have embedded colour profiles: the output to pdfimages -list <file> reads
page   num  type   width height color comp bpc  enc interp  object ID x-ppi y-ppi size ratio
--------------------------------------------------------------------------------------------
   1     0 image    1568  2489  icc     3   8  jpeg   no       170  0   300   300  306K 2.7%
   3     1 image    1550  2437  icc     3   8  jpeg   no        13  0   300   300  592K 5.4%
   4     2 image    1550  2435  icc     3   8  image  no        17  0   300   300 2479K  22%
...
('icc' for all images)

From this file, I'm trying to create one with the ISO Coated V2 300% colour profile required by the printer. These are my settings in the "color management" tab:
colorManagementTab.jpg
As a result, all darker colours are shown as out of gamut.

I'm not trying to achieve a print that shows the colours as shown on my screen, I'm looking for a way to suitably convert the embedded colour profiles of the images to ISO Coated V2 300% (I hope I don't have a misconception here and this is possible with the information available to me). I'd much appreciate any pointers as to how to do this. (I'm on Ubuntu 22.04.1 LTS and using Scribus Version 1.5.8 )

Best

P.S.: This is only the next step, however, the wiki page "color management" and a web search left me somewhat confused as to what PDF version to export to eventually. Any recommendations?

hi vadv55

this exclamation mark tells you that the resolution of your image is higher or lower than specified in the preferences for the preflight verifier.

After inserting an illustration into a Scribus block, a rectangle with an exclamation mark appears in the lower right corner of the block. What does it mean and how to get rid of it? Thanks in advance for any advice on this matter.

I would look into using a PDF tool to split the PDF.

A quick google search found this page, listing several options.

hi rolf

there is another way (sort of a hack...)
  • insert one page after page '1' and one at the end of the file (now you have four pages in a3.)
  • go to file' → 'document setup' → 'layout' and change it to 'facing pages' and the first page to a 'left page'
  • switch to file' → 'document setup' → 'general', change the size to 'a4', the orientation to 'portrait' and check the two boxes to apply the changes to all master pages and document pages.

now you have your content on four pages, but the last page is misplaced. for this you could either move the page to the end with 'windows' → 'arrange pages' and change the first page to a 'right page' in 'document setup' – or you might export the file and rearrange the pages with a .pdf handler...

Layout Issues / Making A4 pages out of an A3 d...
Last post by rweilert - March 09, 2023, 12:11:12 PM
There is a folded A4 flyer and I made it as an A3 landscape document. When folded, it makes 4 A4 pages.

Sometimes I am asked to mail the flyer instead of sending the printed version physically. For those people it is better to have four A4 pages which can be easily printed on any ordinary printer, if necessary.

So I thought about how to "convert" the A3 landscape page into two A4 pages. Is there a standard way to do this in Scribus, or do I have to find my "best pratice" to achieve it?

What I thought of first was to simply mark everything and copy it into another A4 page. But there are 6 layers, is there a way to copy everything in one go? I would then copy it twice, setting the original content once to the left, once to the right of the A4 page (so the rest hangs over to one or the other side resp.).

Or is there an easier way?

Thanks for all ideas!

Yes of course, Scribus 1.5.7 sorry.
As I can't find a 1.5.7 binary for Manjaro, I've downloaded the 1.5.7 sources but there is a known compilation bug...

As I think that the 11 signal is related with footnotes, I've change some parameters in my footnotes settings (Automatic hight and automatic linking) and it seems that the "bug" does not appear anymore and I can create the final PDF with Scribus svn 1.7.

I will investigate a bit more tomorrow.

Thank's for your time and help,
Victor
